PART I

ITEM 1. BUSINESS

GENERAL

Apache Corporation (Apache or the Company), a Delaware corporation formed
in 1954, is an independent energy company that explores for, develops and
produces natural gas, crude oil and natural gas liquids. In North America,
Apache's exploration and production interests are focused on the Gulf of Mexico,
the Anadarko Basin, the Permian Basin, the Gulf Coast and the Western
Sedimentary Basin of Canada. Outside of North America, Apache has exploration
and production interests offshore Western Australia and in Egypt, and
exploration interests in Poland, offshore The People's Republic of China,
offshore the Ivory Coast and in Indonesia. Apache common stock, par value $1.25
per share, has been listed on the New York Stock Exchange since 1969, and on the
Chicago Stock Exchange since 1960.

Apache holds interests in many of its U.S., Canadian and international
properties through operating subsidiaries, such as MW Petroleum Corporation
(MW), Apache Canada Ltd., DEK Energy Company (DEKALB, formerly known as DEKALB
Energy Company), Apache Energy Limited (formerly known as Hadson Energy
Limited), Apache International, Inc., Apache Overseas, Inc. and Apache PHN
Company, Inc. (Phoenix, formerly known as The Phoenix Resource Companies, Inc.).
Properties referred to in this document may be held by those subsidiaries.
Apache treats all operations as one segment of business.

1997 RESULTS

In 1997, Apache had record net income of $154.9 million, or $1.71 per
share, on total revenues of $1.2 billion. Net cash provided by operating
activities during 1997 was $723.8 million.

The year 1997 was Apache's 20th consecutive year of production growth and
10th consecutive year of oil and gas reserves growth. Apache's average daily
production was 68.9 Mbbls of oil and natural gas liquids and 609 MMcf of natural
gas for the year. Giving effect to 1997 production, acquisitions, dispositions
and drilling activity, the Company's estimated proved reserves increased by 79.6
MMboe in 1997 over the prior year to 585.7 MMboe, of which approximately 53
percent was natural gas. Based on 506.2 MMboe reported at year-end 1996,
Apache's reserve growth during the year reflects replacement of 228 percent of
the Company's 1997 production, including approximately 183 percent through
drilling, revisions, recompletions, workovers and other production enhancement
projects. Apache's active drilling and production-enhancement program yielded
321 new producing North American wells out of 399 attempts and involved 675
major North American workover and recompletion projects during the year.

At December 31, 1997, Apache had interests in approximately 4,246 net oil
and gas wells and 1,777,225 net developed acres of oil and gas properties. In
addition, the Company had approximately 601,258 net undeveloped acres under
North American leases and 20,303,930 net undeveloped acres under international
exploration and production rights.

APACHE'S GROWTH STRATEGY

Apache's growth strategy is to increase oil and gas reserves, production,
cash flow and earnings through a combination of exploratory drilling,
development of its inventory of existing projects and property acquisitions
meeting defined financial parameters. The Company's drilling program emphasizes
reserve additions through moderate-risk drilling primarily on its North American
interests, and exploratory drilling primarily on its international interests.
The Company also emphasizes reducing operating costs per unit produced and
selling marginal and non-strategic properties in order to enhance its profit
margins.

Apache's international investments and exploration activities are an
emerging component of its long-term growth strategy. In addition to an active,
moderate-risk drilling program in Apache's North American focus areas,
higher-risk international exploration offers potential for greater rewards and
significant reserve additions. Apache directed its international efforts in 1997
toward development of certain discoveries offshore Western Australia, Egypt and
offshore The People's Republic of China, and toward further exploration efforts

1
4

in those areas and on its concessions offshore the Ivory Coast of western Africa
and in Poland. Apache believes that reserve additions in these international
areas are likely to continue through higher-risk exploration and through
improved production practices and recovery techniques.

For Apache, property acquisition is only one phase in a continuing cycle of
business growth. Apache's aim is to follow each acquisition with a cycle of
reserve enhancement, property consolidation and cash flow acceleration,
facilitating asset growth and debt reduction. This approach requires a well
planned and carefully executed property development program and, where
appropriate, a selective program of property dispositions. It motivates Apache
to target acquisitions that have ascertainable additional reserve potential and
to apply an active drilling, workover and recompletion program to realize the
potential of the acquired undeveloped and partially developed properties. Apache
prefers to operate its properties so that it can best influence their
development; as a result, the Company operates properties accounting for over 78
percent of its production.

1997 ACQUISITIONS AND DISPOSITIONS

On October 8, 1997, the Company entered into three agreements with
subsidiaries of Mobil Exploration & Producing Australia Pty Ltd (Mobil) pursuant
to which the Company acquired all the capital stock of three companies owning
interests in certain oil and gas properties and production facilities offshore
Western Australia (the Harriet/East Spar Properties), on November 20, 1997 (the
Ampolex Group Transaction). The total cost of the Ampolex Group Transaction was
approximately $300 million, of which $218 million represented the purchase price
for the capital stock of the acquired companies and $82 million was applied to
discharge existing intercompany debt of one of the acquired companies.

On December 9, 1997, the Company entered into an agreement with Hardy
Petroleum Limited (Hardy) under which Hardy agreed to purchase a 10 percent
interest in the Company's East Spar field and related production facilities. The
transaction closed on January 28, 1998, with a total sales price of
approximately $63 million in cash, such amount being more than Apache's
allocated cost. The Ampolex Group Transaction was recorded net of these
interests.

The Ampolex Group Transaction increased the Company's interest to 47.5
percent from 22.5 percent in the Carnarvon Basin's Harriet area, which includes
the Varanus Island pipeline, processing and production complex and eight
existing oil and gas fields. The transaction also raised the Company's interest
in the East Spar field, which produces through the Varanus Island facilities, to
45 percent from 20 percent net of the sale to Hardy. Apache operates the
Harriet/East Spar Properties.

EXPLORATION AND PRODUCTION

The Company's North American exploration and production activities were
diversified among five operating regions in 1997, Offshore, Midcontinent,
Western, Gulf Coast and Canada. Approximately 72 percent of the Company's proved
reserves are located in Apache's North American regions. Egypt and Australia are
the Company's most important international regions. The Company's Egyptian
operations are headquartered in Cairo, and Apache conducts its Australian and
Indonesian exploration and production from Perth, Australia. Information
concerning the amount of revenue, operating income and identifiable assets
attributable to U.S., Canadian and international operations is set forth in the
Supplemental Oil and Gas Disclosures under Item 8 below.

Offshore. The Offshore region included all of Apache's interests in
properties offshore Texas and Louisiana. The Offshore region was Apache's
leading region for oil and gas revenues in 1997 with $202 million in revenue
from 12.8 MMboe of production for the year. At December 31, 1997, the Offshore
region held 319,812 net acres, located in both state and federal waters, and
accounted for 45.7 MMboe, or eight percent, of the Company's year-end 1997 total
estimated proved reserves. Apache's operations in the Offshore region focused on
workovers and recompletions, which totaled 58 in the region for 1997. Apache
participated in drilling 27 wells that were drilled in the region during the
year, 14 of which were completed as producers. For 1997, Apache's gas production
from the Offshore region was approximately 66.6 Bcf. At the start of the 1998
fiscal year, the Offshore region was merged into the Gulf Coast region to take
advantage of administrative efficiencies.
2
5

Midcontinent. Apache's Midcontinent region operates in Oklahoma, eastern
Texas, Arkansas and northern Louisiana. The region has focused operations on its
sizable position in the Anadarko Basin of western Oklahoma. Apache has drilled
and operated in the Anadarko Basin for over four decades, developing an
extensive database of geologic information and a substantial acreage position.
The Midcontinent region was Apache's leading producing region for 1997 with
approximately 13.1 MMboe of production generating $197 million in revenue for
the Company.

At December 31, 1997 Apache held an interest in 403,796 net acres in the
region, which accounted for approximately 103.1 MMboe, or 18 percent, of
Apache's total estimated proved reserves. Apache participated in drilling 124
wells in the Midcontinent region during the year, 108 of which were completed as
producing wells. The Company performed 33 workover and recompletion operations
in the region during 1997.

Western. The Western region includes assets in the Permian Basin of western
Texas and New Mexico, the Green River Basin of Colorado and Wyoming, and the San
Juan Basin of New Mexico. In 1997, the Western region produced approximately 9.8
MMboe and $168 million in production revenue. At December 31, 1997, the Company
held 449,270 net acres in the region, which accounted for 136.8 MMboe, or 23
percent, of the Company's total estimated proved reserves. Apache participated
in drilling 124 wells in the Western region, 108 of which were productive wells.
Apache performed 236 workovers and recompletions in the Western region during
the year.

Gulf Coast. The Gulf Coast region encompasses the Texas and Louisiana
coasts, central Texas and Mississippi. In 1997, the Gulf Coast region
contributed approximately $172 million in revenues from production of 9.6 MMboe
for the year. The Company performed 215 workover and recompletion operations
during 1997 in the Gulf Coast region and participated in drilling 43 wells, 31
of which were completed as producers. As of December 31, 1997, the region
encompassed 246,227 net acres, and accounted for 70.9 MMboe, or 12 percent, of
the Company's year-end 1997 total estimated proved reserves.

Canada. Exploration and development activity in the Canadian region is
concentrated in the Provinces of Alberta and British Columbia. The region
produced approximately 6.5 MMboe, 84 percent of which was natural gas, and
generated $61 million in production revenue, six percent of the Company's
production revenues in 1997. Apache participated in drilling 81 wells in this
region during the year, 60 of which were completed as producers. The Company
performed 133 workovers and recompletions on operated wells during 1997. At
December 31, 1997, the region encompassed approximately 317,524 net acres, and
accounted for 66 MMboe, or 11 percent, of the Company's year-end 1997 total
estimated proved reserves.

Egypt. At year end, Apache held 13,621,304 net acres in Egypt with 78.7
MMboe of estimated proved reserves or 13 percent of Apache's total estimated
proved reserves. Apache owns a 75 percent interest in the Qarun Block and a 40
percent interest in the Khalda Block, both in the Western Desert of Egypt.
Future production of gas from Khalda is expected to be delivered for sale to the
Egyptian General Petroleum Corporation (EGPC) at a point west of Alexandria,
Egypt, via a 34-inch gas pipeline, construction of which commenced in 1997 with
completion projected to occur in 1999. The costs of building the pipeline will
be borne by Apache, the other Khalda participants and the owners of a
neighboring block. Construction costs paid by Apache and the other Khalda
participants are recoverable from oil and gas production from the Khalda Block.

Both the Khalda and Qarun Concession Agreements provide that Apache and its
partners in the concessions will pay all of the operating and capital costs for
developing the concessions, while the production will be split between EGPC and
the partners. Up to 40 percent of the oil and gas produced from each of the
concessions is available to the Company and its partners to recover operating
and capital costs for the applicable concession. To the extent eligible costs
exceed 40 percent of the oil and gas produced and sold from a concession in any
given quarter, such excess costs may be carried into future quarters without
limit. The remaining 60 percent of all oil and gas produced from the concessions
is divided between EGPC and Apache and its partners, with the percentage
received by Apache and its partners reducing as the gross daily average of oil
and gas produced on a quarterly basis increases. Under the Khalda Agreement,
capital costs are amortized over four years, while the Qarun agreement provides
for a five year amortization.

In addition to the Qarun and Khalda Blocks, Apache holds interests in the
Darag Block in the northern Gulf of Suez, the East Beni Suef and Asyout Blocks
to the south of the Qarun Block, and three other blocks in the Western Desert of
Egypt, the North East Abu Gharadig Block, the East Bahariya Block, and the West
Mediterranean Block No. 1 (partly onshore and partly offshore). The latter three
blocks were purchased from Mobil Exploration Egypt, Inc. in January 1997, and
Apache's interest in the West Mediterranean Block was increased to 66 percent in
an October 1997 transaction with Amoco Egypt West Mediterranean B.V. Apache also
acquired interests in the Ras El Hekma and Ras Kanayes concessions from Repsol
Exploracion Egipta S.A. in December 1997. Exploratory drilling on the East Beni
Suef Block commenced in 1997 with a significant discovery made on the #1 well.
Delineation drilling is continuing in 1998. Due to conflicting governmental
requirements regarding the placement of drilling rigs on the Darag Block, the
Company is presently unable to explore on the block. Negotiations with
appropriate authorities are continuing to attempt to resolve the impasse and
Apache may ultimately relinquish the Darag concession.

Australia. Western Australia became an important region for Apache after
the 1993 acquisition of Hadson Energy Resources Corporation (subsequently known
as Apache Energy Resources Corporation or AERC). In 1997, natural gas production
in the region increased by 88 percent from the prior year to approximately 26
MMcf/d. Apache acts as operator for most of its Western Australia properties
through a wholly-owned subsidiary, Apache Energy Limited (AEL). During 1997,
Apache's estimated proved reserves in Australia increased by 156 percent to 80
MMboe, or 14 percent of the Company's year-end total estimated proved reserves.
The increase reflects, among other matters, the acquisition of three companies
with holdings in the East Spar and Harriet fields. As of December 31, 1997,
Apache held 159,850 net developed acres and 1,104,440 net undeveloped acres in
Western Australia. Through AEL and its subsidiaries, Apache also operates the
Harriet Gas Gathering Project, a gas processing and compression facility with a
throughput capacity of 175 MMcf/d, and a 60-mile, 12-inch offshore pipeline with
a throughput capacity of 175 MMcf/d that connects to a pipeline grid onshore.
See "1997 Acquisitions and Dispositions" and "Oil and Natural Gas Marketing."

Other International Operations. Outside of Canada, Egypt and Australia,
Apache currently has exploration interests in Poland, offshore The People's
Republic of China, offshore the Ivory Coast and in Indonesia.

Effective April 16, 1997, Apache entered into an agreement with FX Energy,
Inc. (FX Energy) pursuant to which Apache assumed operatorship and a 50 percent
interest in over 5.5 million acres in Poland located near Lublin, southeast of
Warsaw. The Company has also acquired additional acreage in Poland in which FX
Energy does not participate, giving Apache interests in 8,176,065 total gross
undeveloped acres and 5,563,542 net undeveloped acres as of December 31, 1997.
The concessions in Poland include requirements for Apache to drill at least
eleven wells and to shoot at least 1,290 miles of seismic data. In February
1998, Apache entered into an additional agreement with FX Energy, acquiring a 50
percent interest in approximately 3 million acres in the Carpathian area near
the southern border of Poland and options to participate at the present interest
in a further 2.275 million acres in the Pomeranian area of northwest Poland.
Apache's operations in Poland are headquartered in Warsaw.

Apache is also the operator, with a 50 percent interest, of the Zhao Dong
Block in Bohai Bay, offshore The People's Republic of China. In 1994 and 1995,
discovery wells tested at rates between 1,300 and 4,000 b/d of oil. The Company
elected to proceed with the second exploration phase, commencing in May 1996,
which involved a commitment to drill two additional exploratory wells. In early
1997, one well tested at rates up to 11,571 b/d of oil and another tested at
rates up to 15,359 b/d, and the Company is currently evaluating the discovery
areas for commercial potential. An overall development plan for the C and D
Fields in the Zhao Dong Block was submitted to Chinese authorities in late 1997
and is awaiting approval.

In the Ivory Coast, Apache drilled an exploratory well in 1996 on the CI-27
offshore Block, confirming the existence of substantial reserves of gas in the
Foxtrot field and the producibility of some oil from the field's lower horizons.
Apache is operator of the block, holding a 24 percent interest. In March 1997,
Apache and its partners signed a 10 year take or pay contract to supply
approximately 168 Bcf of gas to a power plant in Abidjan at 30 MMcf per day
initially, rising to 50 MMcf per day in the third year. Gas deliveries are to
commence in 1999, upon completion of a pipeline.

In Indonesia, Apache holds a 39 percent interest in the Bentu Segat Block
on Central Sumatra, on which an undeveloped gas field is located.

OIL AND NATURAL GAS MARKETING

On October 27, 1995, wholly owned affiliates of each of Apache, Oryx Energy
Company and Parker & Parsley Petroleum Company (Parker & Parsley) formed
Producers Energy Marketing, LLC, a Delaware limited liability company
(ProEnergy). ProEnergy became fully operational on April 1, 1996, and markets
substantially all of its members' domestic natural gas pursuant to member gas
purchase agreements having an initial term of 10 years, subject to early
termination following specified events. The price of gas purchased by ProEnergy
from its members is based upon agreed to published indexes. ProEnergy also
provides its members with certain contract administration and other services. In
December 1997, Parker & Parsley gave notice to the other members that it was
withdrawing from ProEnergy effective as of January 1, 1998.

ProEnergy's limited liability company agreement provides that capital
funding obligations, allocations of profit and loss, and voting rights are
calculated based upon the members' respective throughputs of natural gas sold to
ProEnergy. So long as there are two or more members, the approval of any action
requires the votes of at least two members holding the requisite voting
interests. Each member's liability with respect to future capital funding
obligations is subject to certain limitations. Natural gas throughputs are
calculated, profit distributed, and/or capital called on a quarterly basis. As
of December 31, 1997, the Company held an approximate 48 percent interest in
ProEnergy.

Apache is also delivering natural gas under several long-term supply
agreements with terms greater than one-year. In 1997, Apache delivered an
average of 135 MMcf/d under such contracts at an average price of $2.48 per Mcf.

Apache assumed its own U.S. crude oil marketing operations in 1992. Most of
Apache's U.S. crude oil production is sold through lease-level marketing to
refiners, traders and transporters, generally under 30 day contracts that renew
automatically until canceled. Oil produced from Canadian properties is sold to
crude oil purchasers or refiners at market prices, which depend on worldwide
crude prices adjusted for transportation and crude quality. Natural gas produced
from Canadian properties is sold to major aggregators of natural gas, gas
marketers and direct users under long-term and short-term contracts. The oil and
gas contracts provide for sales at specified prices, or at prices that are
subject to change due to market conditions.

The Company diversifies the markets for its Canadian gas production by
selling directly or indirectly to customers through aggregators and brokers in
the United States and Canada. Apache transports natural gas via the Company's
firm transportation contracts to California (12 MMcf/d) and to the Province of
Ontario, Canada (four MMcf/d) through end-users' firm transportation contracts.
Pursuant to an agreement entered into in 1994, the Company is also selling five
MMcf/d of natural gas to the Hermiston Cogeneration Project, located in the
Pacific Northwest of the United States. In 1996, the Company entered into an
agreement with Westcoast Gas Services, Inc. for the sale of 5,000 MMBtu/d for
delivery in the United States for a 10 year term. Sales under the contract are
contingent on regulatory approval of the required pipeline expansion, and are
expected to begin in 1998.

In Australia, the Company entered into seven gas sales contracts during
1997 and has a total of 13 contracts for periods of five to 11 years, to deliver
260 Bcf of AEL's gas from its Harriet and East Spar fields for mining, power
generation, nickel refining, ammonia production and other industrial and
domestic uses. Under these contacts AEL is required to deliver its gas at
contract rates of approximately 50 MMcf/day increasing to 80 MMcf/day by the
year 2000, with take or pay provisions, net to AEL, of approximately 14 Bcf/year
increasing to 20 Bcf/year by the year 2000. Apache operates both the Harriet and
the East Spar Joint Ventures, holding a 47.5 percent interest in Harriet and a
45 percent interest in East Spar.

AEL marketed all oil and natural gas liquids produced from its interests in
the Harriet and East Spar fields during 1997 through a contract with Glencore
International AG (Glencore). Pricing under the contract in 1997 represented a
fixed premium to the quoted market prices of Tapis crude oil, with payment made
in U.S. dollars. In 1997, the weighted average price based on regional
production was $20.51 per barrel. At the

5
8

beginning of January 1998, the Glencore contract was terminated and replaced by
a similar contract with Mitsui Oil (Asia) Pty. Ltd.

In Egypt, oil from the Qarun Block is delivered by pipeline to tanks owned
by the Company and its partners in the Qarun Concession at the Dashour pumping
station northeast of the Qarun Block or by truck to the Tebbin refinery south of
Alexandria, Egypt. At the discretion of the operator of the pipelines, oil from
the Qarun Block is put into the two 42-inch diameter SUMED pipelines, which
transport significant quantities of Egyptian and other crude oil from the Gulf
of Suez to Sidi Kherir, west of Alexandria, Egypt, on the Mediterranean Coast.
All Qarun and Khalda crude oil is currently sold to EGPC. In 1996, the Company
and its partners in the Khalda Block entered into a take or pay contract with
EGPC, which obligates EGPC to pay for 75 percent of 200 MMcf/d of future
production of gas from the Khalda Block. Sales of gas under the contract are
expected to begin in 1999 upon completion of a gas pipeline from the Khalda
Block. In late 1997, the same sellers entered into a supplement to the contract
with EGPC to sell an additional 50 MMcf/d through a southern gas line to be
constructed by the Company and its partners from the Khalda Block to a point
near the Qarun Block to tie into an existing gas pipeline.

OIL AND NATURAL GAS PRICES

Natural gas prices remained volatile during 1997, with Apache's realized
prices ranging from $3.38 per MMbtu in January to $1.78 per MMbtu in April.
Fluctuations are largely due to natural gas supply and demand perceptions.
Apache's average realized gas price of $2.28 per Mcf for 1997 increased 13
percent from the prior-year average of $2.02 per Mcf, and its 1996 average
realized natural gas price was 29 percent higher than the 1995 average price of
$1.57 per Mcf.

Due to minimum price contracts which escalate at an average of 80 percent
of the Australian consumer price index, AEL's natural gas production in Western
Australia is not subject to the same degree of price volatility as Apache's U.S.
and Canadian gas production; however, natural gas sales under such Australian
minimum price contracts represent less than two percent of the Company's total
natural gas sales at the end of 1997. Total Australian gas sales in 1997,
including long-term contracts and spot sales averaged $1.78 per Mcf, a nine
percent decrease from the 1996 average of $1.96 per Mcf.

In Egypt, all oil production from the Khalda and Qarun Blocks is currently
sold to EGPC on a spot basis at a "Western Desert" price, which is applied to
virtually all production from the area and is announced from time to time by
EGPC. In 1997, the average price was $18.65 per barrel. Discussions with EGPC
regarding the possibility of exporting Qarun oil production are continuing. Once
gas sales from the Khalda Block commence, the gas is expected to be sold for a
price which, on a Btu basis, is equivalent to 85 percent of the price of Suez
Blend crude oil, FOB Mediterranean.

Oil prices remained subject to unpredictable political and economic forces
during 1997 experiencing fluctuations similar to those seen in natural gas
prices for the year. Apache believes that oil prices will continue to fluctuate
in response to changes in the policies of the Organization of Petroleum
Exporting Countries (OPEC), events in the Middle East and other factors
associated with the world political environment. As a result of the many
uncertainties associated with levels of production maintained by OPEC and other
oil producing countries, the availabilities of worldwide energy supplies and the
competitive relationships and consumer perceptions of various energy sources,
the Company is unable to predict what changes will occur in crude oil and
natural gas prices.

In 1997, Apache's realized worldwide crude oil price ranged from $24.17 per
barrel in January to $16.71 per barrel in December. The average crude oil price
of $19.20 per barrel in 1997 was down eight percent from the average price of
$20.84 per barrel in 1996, but 12 percent higher than the average price of
$17.09 per barrel in 1995. The Company's average crude oil price for its
Australian production was $20.51 per barrel in 1997, eight percent less than the
average price in 1996.

Terms of the acquisition of MW from Amoco Production Company (Amoco)
included an oil and gas price sharing provision under which certain price
sharing payments may be payable to Amoco. Under this provision, to the extent
that oil prices exceed specified reference prices that rise to $33.12 per barrel
over the

6
9

eight-year period ending June 30, 1999, and to the extent that gas prices
exceeded specified reference prices that rose to $2.68 per Mcf over the
five-year period ended June 30, 1996, Apache will share the excess price
realization with Amoco on a portion of the MW production. No price sharing
payments were required in 1997.

From time to time, Apache buys or sells contracts to hedge a limited
portion of its future oil and gas production against exposure to spot market
price changes. See Note 9 to the Company's consolidated financial statements
under Item 8 below.

The Company's business has been and will continue to be affected by future
worldwide changes in oil and gas prices and the relationship between the prices
of oil and gas. No assurance can be given as to the trend in, or level of,
future oil and gas prices.

FULL COST CEILING TEST

Under the full cost accounting rules of the Securities and Exchange
Commission (SEC), the Company reviews the carrying value of its oil and gas
properties each quarter on a country-by-country basis. Under full cost
accounting rules, capitalized costs of oil and gas properties may not exceed the
present value of estimated future net revenues from proved reserves, discounted
at 10 percent, plus the lower of cost or fair market value of unproved
properties, as adjusted for related tax effects and deferred income taxes.
Application of these rules generally requires pricing future production at the
unescalated oil and gas prices in effect at the end of each fiscal quarter and
requires a write-down if the "ceiling" is exceeded, even if prices declined for
only a short period of time. The Company had no write-downs due to ceiling test
limitations during 1997. Under current pricing there is the potential, while not
a certainty, that a write-off may occur. If a write-down is required, the
one-time charge to earnings would not impact cash flow from operating
activities.

EFFECT OF VOLATILE PRICES

The Company continually analyzes, forecasts and updates its estimates of
energy prices for its internal use in planning, budgeting, and valuation and
reserve estimates. The Company's future financial condition and results of
operations will depend upon the prices received for the Company's oil and
natural gas production and the costs of acquiring, finding, developing and
producing reserves. Prices for oil and natural gas are subject to fluctuations
in response to relatively minor changes in supply, market uncertainty and a
variety of additional factors that are beyond the control of the Company. These
factors include worldwide political instability (especially in the Middle East
and other oil-producing regions), the foreign supply of oil and gas, the price
of foreign imports, the level of consumer product demand, government regulations
and taxes, the price and availability of alternative fuels and the overall
economic environment. A substantial or extended decline in oil and gas prices
would have a material adverse effect on the Company's financial position,
results of operations, quantities of oil and gas that may be economically
produced and access to capital. In addition, the sale of the Company's oil and
gas production depends on a number of factors beyond the Company's control,
including the availability and capacity of transportation and processing
facilities. Oil and natural gas prices have historically been and are likely to
continue to be volatile. Such volatility makes it difficult to estimate the
value of producing properties in acquisitions and to budget and project the
return on exploration and development projects involving the Company's oil and
gas properties. In addition, unusually volatile prices often disrupt the market
for oil and gas properties, as buyers and sellers have more difficulty agreeing
on the purchase price of properties.

RESERVES; RATES OF PRODUCTION; DEVELOPMENT EXPENDITURES; CASH FLOW

There are numerous uncertainties inherent in estimating quantities of oil
and natural gas reserves of any category and in projecting future rates of
production and timing of development expenditures which underlie such reserve
estimates, including many factors beyond the control of the Company. Reserve
data represents only estimates. In addition, the estimates of future net cash
flows from proved reserves of the Company and the present value thereof are
based upon various assumptions about future production levels, prices and costs
that may prove to be incorrect over time (see below). Any significant variance
from the assumptions could result in the actual quantity of the Company's
reserves and future net cash flows therefrom being materially

7
10

different from the estimates. In addition, the Company's estimated reserves may
be subject to downward or upward revision based upon production history, results
of future exploration and development, prevailing oil and gas prices, operating
and development costs and other factors. The rate of production from oil and gas
properties declines as reserves are depleted. Except to the extent that the
Company acquires additional properties containing proved reserves, conducts
successful exploration and development activities or, through engineering
studies, identifies additional behind-pipe zones or secondary recovery reserves,
the proved reserves of the Company will decline materially as reserves are
produced. Future oil and gas production is, therefore, highly dependent upon the
Company's level of success in acquiring or finding additional reserves.

GOVERNMENT REGULATION OF THE OIL AND GAS INDUSTRY

The Company's exploration, production and marketing operations are
regulated extensively at the federal, state and local levels, as well as by
other countries in which the Company does business. Oil and gas exploration,
development and production activities are subject to various laws and
regulations governing a wide variety of matters. For example,
hydrocarbon-producing states have statutes or regulations addressing
conservation practices and the protection of correlative rights, and such
regulations may affect Apache's operations and limit the quantity of
hydrocarbons Apache may produce and sell. Other regulated matters include
marketing, pricing, transportation, and valuation of royalty payments.

At the U.S. federal level, the Federal Energy Regulatory Commission (FERC)
regulates interstate transportation of natural gas under the Natural Gas Act.
Effective January 1, 1993, the Natural Gas Wellhead Decontrol Act deregulated
natural gas prices for all "first sales" of natural gas, which includes all
sales by Apache of its own production. As a result, all sales of the Company's
natural gas produced in the U.S. may be sold at market prices, unless otherwise
committed by contract.

Apache's gas sales are affected by regulation of intrastate and interstate
gas transportation. In an attempt to promote competition, the FERC has issued a
series of orders which have altered significantly the marketing and
transportation of natural gas. The effect of these orders has been to enable the
Company to market its natural gas production to purchasers other than the
interstate pipelines located in the vicinity of its producing properties. The
Company believes that these changes have generally improved the Company's access
to transportation. To date, Apache has not experienced any material adverse
effect on its gas marketing activities as a result of these FERC orders;
however, the Company cannot predict what new regulations may be adopted by the
FERC and other regulatory authorities, or what effect subsequent regulations may
have on its future gas marketing activities.

ENVIRONMENTAL MATTERS

Apache, as an owner or lessee and operator of oil and gas properties, is
subject to various federal, provincial, state, local and foreign country laws
and regulations relating to discharge of materials into, and protection of, the
environment. These laws and regulations may, among other things, impose
liability on the lessee under an oil and gas lease for the cost of pollution
clean-up resulting from operations, subject the lessee to liability for
pollution damages, and require suspension or cessation of operations in affected
areas.

Apache maintains insurance coverage which it believes is customary in the
industry, although it is not fully insured against all environmental risks. The
Company is not aware of any environmental claims existing as of December 31,
1997, which would have a material impact upon the Company's financial position
or results of operations.

Apache has made and will continue to make expenditures in its efforts to
comply with these requirements, which it believes are necessary business costs
in the oil and gas industry. The Company has established policies for continuing
compliance with environmental laws and regulations, including regulations
applicable to its operations in Canada, Australia and other countries. Apache
also has established operational procedures and training programs designed to
minimize the environmental impact of its field facilities. The costs incurred by
these policies and procedures are inextricably connected to normal operating
expenses such that the Company is unable to separate the expenses related to
environmental matters; however, the Company does not believe any such additional
expenses are material to its financial position or results of operations.
8
11

Although environmental requirements have a substantial impact upon the
energy industry, generally these requirements do not appear to affect Apache any
differently, or to any greater or lesser extent, than other companies in the
industry. Apache does not believe that compliance with federal, state, local or
foreign country provisions regulating the discharge of materials into the
environment, or otherwise relating to the protection of the environment, will
have a material adverse effect upon the capital expenditures, earnings or
competitive position of the Company or its subsidiaries; however, there is no
assurance that changes in or additions to laws or regulations regarding the
protection of the environment will not have such an impact.

COMPETITION

The oil and gas industry is highly competitive. Because oil and gas are
fungible commodities, the principal form of competition with respect to product
sales is price competition. Apache strives to maintain the lowest finding and
production costs possible to maximize profits.

As an independent oil and gas company, Apache frequently competes for
reserve acquisitions, exploration leases, licenses, concessions and marketing
agreements against companies with substantially larger financial and other
resources than Apache possesses. Moreover, many competitors have established
strategic long-term positions and maintain strong governmental relationships in
countries in which the Company may seek new entry. Apache expects this high
degree of competition to continue.

INSURANCE

Exploration for and production of oil and natural gas can be hazardous,
involving unforeseen occurrences such as blowouts, cratering, fires and loss of
well control, which can result in damage to or destruction of wells or
production facilities, injury to persons, loss of life or damage to property or
the environment. The Company maintains insurance against certain losses or
liabilities arising from its operations in accordance with customary industry
practices and in amounts that management believes to be prudent; however,
insurance is not available to the Company against all operational risks.

HEDGING

To the extent that the Company engages in hedging activities, it may be
prevented from realizing the benefits of price increases above the levels of the
hedges. In addition, the Company is subject to basis risk when it engages in
hedging transactions, particularly where transportation constraints restrict the
Company's ability to deliver oil and gas volumes to the delivery point to which
the hedging transaction is indexed.

ACQUISITION RISKS

The Company from time to time acquires oil and gas properties. Although the
Company performs a review of the acquired properties that it believes is
consistent with industry practices, such reviews are inherently incomplete. It
generally is not feasible to review in depth every individual property involved
in each acquisition. Ordinarily the Company will focus its review efforts on the
higher-value properties and will sample the remainder. However, even a detailed
review of records and properties may not necessarily reveal existing or
potential problems, nor will it permit a buyer to become sufficiently familiar
with the properties to assess fully their deficiencies and potential.
Inspections may not always be performed on every well, and environmental
problems, such as ground water contamination, are not necessarily observable
even when an inspection is undertaken. Even when problems are identified, the
Company often assumes certain environmental and other risks and liabilities in
connection with acquired properties. There are numerous uncertainties inherent
in estimating quantities of proved oil and gas reserves and actual future
production rates and associated costs with respect to acquired properties, and
actual results may vary substantially from those assumed in the estimates (see
above). In addition, there can be no assurance that acquisitions will not have
an adverse effect upon the Company's operating results, particularly during the
periods in which the operations of acquired businesses are being integrated into
the Company's ongoing operations.

9
12

GENERAL ECONOMIC CONDITIONS

Virtually all of the Company's operations are subject to the risks and
uncertainties of general economic conditions (domestically, in specific regions
of the United States and Canada, and internationally), the outcome of pending
and/or potential legal or regulatory proceedings, changes in environmental, tax,
labor and other laws and regulations to which the Company is subject, and the
condition of the capital markets utilized by Company to finance its operations.

RISKS OF NON-U.S. OPERATIONS

The Company's non-U.S. oil and natural gas exploration, development and
production activities are subject to political and economic uncertainties
(including but not limited to changes, sometimes frequent or marked, in
governmental energy policies or the personnel administering them), expropriation
of property, cancellation or modification of contract rights, foreign exchange
restrictions, currency fluctuations, royalty and tax increases and other risks
arising out of foreign governmental sovereignty over the areas in which the
Company's operations are conducted, as well as risks of loss due to civil
strife, acts of war, guerrilla activities and insurrection. These risks may be
higher in the developing countries in which the Company conducts such
activities. Consequently, the company's non-U.S. exploration, development and
production activities may be substantially affected by factors beyond the
Company's control, any of which could materially adversely affect the Company's
financial position or results of operations. Furthermore, in the event of a
dispute arising from non-U.S. operations, the Company may be subject to the
exclusive jurisdiction of courts outside the U.S. or may not be successful in
subjecting non-U.S. persons to the jurisdiction of the courts in the U.S., which
could adversely affect the outcome of such dispute.

EMPLOYEES

On December 31, 1997, Apache had 1,287 employees.

OFFICES

Apache's principal executive offices are located at One Post Oak Central,
2000 Post Oak Boulevard, Suite 100, Houston, Texas 77056-4400. At year-end 1997,
the Company maintained regional exploration and production offices in Tulsa,
Oklahoma; Houston, Texas; Calgary, Alberta; Cairo, Egypt; Perth, Western
Australia; and Warsaw, Poland.

ESTIMATED RESERVES AND RESERVE VALUE INFORMATION

The following information relating to estimated reserve quantities, reserve
values and discounted future net revenues is derived from, and qualified in its
entirety by reference to, the more complete reserve and revenue information and
assumptions included in the Company's Supplemental Oil and Gas Disclosures under
Item 8 below. The Company's estimates of proved reserve quantities of its U.S.,
Canadian and international properties have been subject to review by Ryder Scott
Company Petroleum Engineers. In 1996, the proved reserve quantities of certain
of the Company's Egyptian properties were reviewed by Netherland, Sewell &
Associates, Inc. There are numerous uncertainties inherent in estimating
quantities of proved reserves and projecting future rates of production and
timing of development expenditures. The following reserve

The Company believes that no major discovery or other favorable or adverse
event has occurred since December 31, 1997, which would cause a significant
change in the estimated proved reserves reported herein. The estimates above are
based on year-end pricing in accordance with the SEC guidelines and do not
reflect current prices. Since January 1, 1997, no oil or gas reserve information
has been filed with, or included in any

report to, any U.S. authority or agency other than the SEC and the Energy
Information Administration (EIA). The basis of reporting reserves to the EIA for
the Company's reserves is identical to that set forth in the foregoing table.

TITLE TO INTERESTS

The Company believes that its title to the various interests set forth
above is satisfactory and consistent with the standards generally accepted in

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

OVERVIEW

Apache achieved record earnings and cash flow on both an absolute and per
share basis during 1997. Higher natural gas prices, while contributing to the
year's improvements, were partially offset by lower oil prices. More than
product prices, the primary driver behind Apache's 1997 record performance was
increased production volumes, characterized by moderate growth in North American
gas production and substantial increases in oil volumes abroad.

The year's $154.9 million of earnings, coupled with a $75 million
conversion of debt to equity in November and $611 million of cash provided
before changes in working capital and other adjustments (cash flow from
operations), enabled Apache to end 1997 with a debt-to-capitalization ratio of
46.8 percent, up from 44.9 percent in 1996, despite $685.4 million invested in
exploration and development activities and $225.9 million of property
acquisitions. At year-end, approximately 69 percent of Apache's debt was locked
in at fixed rates averaging 7.42 percent.

Other specifics include:

Increased production and higher gas prices -- Higher oil and gas production
and natural gas prices contributed to record earnings and cash flow in 1997.
Egyptian oil development, a full year of production from Egyptian properties
acquired in 1996, and North American gas drilling drove the increased production
for 1997. Apache's oil production increased 25 percent from 1996 to 1997, which
added $92.6 million to revenues. Natural gas production increased nine percent
from 1996 to 1997, which contributed $38.5 million to the increase in revenues.
Apache's average realized natural gas price for 1997 was up 13 percent over
1996, favorably impacting revenues by $51.3 million.

Debt refinancing -- In January 1997, the Company established a $300 million
commercial paper program and expanded that program in June 1997 to $700 million.
Apache also replaced its $1 billion global borrowing-base credit facility with a
new $1 billion global corporate credit facility in June 1997. Apache issued $150
million of senior unsecured 50 year, 7.375-percent debentures in August 1997.
Three of the Company's Egyptian subsidiaries entered into a $250 million
secured, revolving credit facility in October 1997. Apache's Australian finance
subsidiary issued, in December 1997, $170 million of 10 year, 6.5-percent notes
guaranteed by Apache. The Company also received a rating upgrade on its senior
and subordinated long-term debt from Standard & Poor's in January 1997.

RESULTS OF OPERATIONS

NET INCOME AND REVENUE

Apache reported 1997 net income of $154.9 million, an increase of 28
percent or $33.5 million over 1996. The increase is primarily due to higher oil
and gas production, higher natural gas prices and lower operating costs per unit
of production. Basic net income per common share rose to $1.71 compared to $1.42
in 1996; diluted net income per common share increased to $1.65 in 1997 from
$1.38 in 1996. Net income of $121.4 million for 1996 rose from $20.2 million in
1995. Basic net income per common share increased five-fold in 1996 from $.28 in
1995; diluted net income per common share was also $.28 in 1995. The increase
was attributed to higher oil and gas prices and increased oil production.

Revenues increased 20 percent to $1.2 billion in 1997. Oil and natural gas
production revenues increased 18 percent, primarily due to increased oil and gas
production and natural gas prices. Crude oil, including natural gas liquids, and
natural gas contributed 49 percent and 51 percent, respectively, of total oil
and gas production revenues during 1997. Revenues increased 30 percent in 1996
to $977.2 million. Revenues for 1995 were $750.7 million. In 1996, crude oil,
including natural gas liquids, contributed 50 percent and natural gas
contributed 50 percent of total oil and gas production revenues.

Natural gas revenues increased by 22 percent from 1996 to 1997 due to
increased natural gas prices and increased production. The average price
received in 1997 was $.26 per Mcf, or 13 percent, higher than 1996. The Company
periodically engages in hedging activities, including fixed-price physical
contracts and financial contracts. Apache realized gains from open hedging
positions favorably impacting the gas price by $.06 per Mcf. Losses under
long-term fixed-price physical contracts negated the hedging gains reducing the
gas price by $.06 per Mcf. The higher prices in 1997 were the result of
favorable North American market conditions. Natural gas prices in Australia
declined in 1997 due to the effect of exchange rates on fixed Australian dollar-

18
21

denominated gas contracts. Natural gas production for the United States
increased four percent from 1996 to 1997 due to drilling results in the
Midcontinent and Offshore regions. Canadian natural gas production increased 20
percent due to acquisition and drilling activity. Natural gas production from
Australia increased 88 percent from 1996 to 1997. Australian production
increases resulted primarily from a full year of production from the Company's
East Spar properties, which came on line in November 1996, and properties
acquired in the Ampolex Group Transaction.

Natural gas revenues increased 26 percent from 1995 to 1996. Average
natural gas prices were $.45 per Mcf, or 29 percent, higher in 1996 than 1995.
The Company's net hedging activity, including fixed-price physical contracts and
financial contracts reduced the reported prices by $.09 per Mcf in 1996,
compared to a $.07 per Mcf gain in 1995. Natural gas production declined three
percent from 1995 to 1996, primarily due to the natural decline of older
properties in the Company's Offshore and Gulf Coast regions and the sale of
producing properties in late 1995.

Oil revenues increased 15 percent from 1996 to 1997. Egyptian oil
production more than doubled from 1997 due to development activity and the first
full year of production from the Company's Egyptian properties acquired in 1996.
Australian oil production increased 90 percent from 1996 to 1997 due to the
Agincourt prospect. These production increases were partially offset by a
decrease of eight percent in average oil prices received during 1997 due to poor
market conditions.

Oil revenues increased 30 percent from 1995 to 1996, primarily due to
properties acquired in connection with the Phoenix merger and new Egyptian
production from the Company's Qarun field. Decreases in domestic production due
to United States property sales in late 1995, partially offset the impact of
Egyptian production. The average oil price increased 22 percent from 1995 to
1996.

NGL revenues were slightly higher in 1997 than in 1996. NGL production
increased 19 percent from 1996 to 1997, which was offset by a 14 percent
decrease in average prices. NGL revenues increased 27 percent from 1995 to 1996.
Average prices in 1996 were 36 percent higher than in 1995 due to improved
market conditions. The increase in prices was partially offset by a seven
percent decline in production.

OTHER REVENUES AND OPERATING EXPENSES

Gas gathering, processing and marketing revenues increased 38 percent to
$197.0 million in 1997 from 1996. Increased gas volumes and higher gas prices in
1997 drove this increase. Correspondingly, gas gathering, processing and
marketing costs increased in 1997 by 40 percent to $194.3 million. Thus, lower
margins were realized in 1997. Lower crude oil trading margins and lower
pipeline gathering fees were mitigated by higher gas purchase and resale margins
in 1997. During 1996, gas gathering, processing and marketing revenues increased
47 percent to $142.9 million from $97.2 million in 1995. Lower margins were also
realized in 1996 as compared to 1995.

Equity in income (loss) of affiliates represents Apache's share of
ProEnergy losses. Equity in loss of affiliate was $1.7 million and $.3 million
in 1997 and 1996, respectively.

Other revenue for 1997 was a loss of $2.8 million. This amount includes
$4.8 million in foreign currency transaction losses on Canadian dollars and $1.2
million in foreign currency transaction losses on Australian dollars. Canadian
royalty credits of $1.0 million and proceeds received from settlements of $1.8
million partially mitigated these losses. For 1996, other revenue of $1.4
million included a gain on the sale of stock held for investment of $.8 million
and Canadian royalty credits of $1.2 million. Currency transaction losses on
Canadian dollars of $.9 million partially offset these revenues. Other revenue
for 1995 was $.4 million. This amount included $4.3 million in proceeds received
from settlements, $2.2 million in gains from the sales of non-oil and gas
assets, $1.1 million of Canadian royalty credits and $2.1 million of other
income. Losses from the decoupling of NYMEX and wellhead gas prices of $9.3
million offset these revenues.

The Company's depreciation, depletion and amortization (DD&A) expense
increased to $381.4 million in 1997 from $315.1 million in 1996. On an
equivalent barrel basis, full cost DD&A expense increased $.33 per boe, from
$5.44 per boe in 1996 to $5.77 per boe in 1997. Reserve revisions due to price
declines during the

19
22

first part of 1997 and an increased cost environment in North America negatively
impacted the 1997 rate. Full cost DD&A expense increased in 1996 from $288.4
million, or $5.32 per boe, in 1995.

Apache's operating costs increased three percent to $231.4 million in 1997
from $225.5 million in 1996. Lease operating expense (LOE), excluding severance
taxes, increased from $186.4 million in 1996 to $190.8 million in 1997. LOE
increased as a result of Egyptian oil production enhancements and North American
gas production gains. On an equivalent barrel basis, LOE for 1997 averaged $3.07
per boe, a $.36 decline from $3.43 per boe in 1996. Production increased with a
lower incremental LOE than the 1996 average per unit cost. Specifically, North
American gas production and Egyptian oil production carry much lower per unit
costs than the 1996 property profile. The divestiture of marginal properties in
the U.S. also favorably impacted LOE per boe in 1997. Operating costs increased
seven percent in 1996 from $211.7 million in 1995. LOE, excluding severance
taxes, increased three percent in 1996 from $181.1 million in 1995. LOE per boe
increased three percent in 1996 from $3.34 per boe in 1995. The increase was
driven by a flat domestic cost structure with declining production in the Gulf
Coast region. The Phoenix acquisition in 1995 also increased LOE per boe.
Mitigating these increases was decreased LOE per boe in the Midcontinent region
due to incremental production added through the drillbit.

Administrative, selling and other costs increased $2.3 million, or six
percent, from 1996 to 1997. Under a new bonus plan initiated in 1997, Apache
provided incentive compensation to all employees based on the achievement of
targeted performance, which was the primary reason for the increase. On an
equivalent barrel basis, general and administrative (G&A) expense declined from
$.66 per boe in 1996 to $.62 per boe in 1997. Production increases were not met
with rising administrative costs. Administrative, selling and other costs were
lower in 1996 than in 1995 due to the Company's continuing efforts to control
costs. On an equivalent barrel basis, G&A expense declined two percent in 1996
from $.67 per boe in 1995.

Net financing costs for 1997 increased $10.7 million, or 17 percent, over
1996. Gross interest expense increased by $15.3 million due to higher average
aggregate debt outstanding at higher average interest rates, which resulted from
the extension of Apache's debt maturities. Average aggregate debt outstanding
and average interest rates increased to $1.4 billion and 7.69 percent,
respectively, from $1.2 billion and 7.40 percent in 1996. In 1997, Apache wrote
off $1.2 million in deferred loan costs related to cancellation of two secured
credit facilities with the International Finance Corporation (IFC). Additional
capitalized interest of $5.8 million in 1997 mitigated these increases.
Capitalized interest is based on the carrying value of unproved properties.
Higher international unevaluated costs caused the increase in 1997. Net
financing costs for 1996 decreased $9.0 million, or 13 percent, from the prior
year due to higher amounts of capitalized interest, partially offset by higher
gross interest costs. Capitalized interest increased $11.7 million for 1996 due
to an increase in the unproved property base resulting from acquisitions made in
1995 and 1996. Gross interest expense increased $1.8 million for 1996 as
compared to 1995. Average outstanding debt increased $78.8 million compared to
1995. Offsetting this increase was a decline of .36 percent in Apache's weighted
average interest rate.

MARKET RISK

COMMODITY RISK

The Company's major market risk exposure is in the pricing applicable to
its oil and gas production. Realized pricing is primarily driven by the
prevailing worldwide price for crude oil and spot prices applicable to its
United States and Canadian natural gas production. Historically, prices received
for oil and gas production have been volatile and unpredictable. Pricing
volatility is expected to continue. Gas price realizations ranged from a monthly
low of $1.78 per Mcf to a monthly high of $3.38 per Mcf during 1997. Oil prices
ranged from a low of $16.71 per barrel to a high of $24.17 per barrel during the
same period.

The Company periodically enters into hedging activities with respect to a
portion of its projected oil and natural gas production through a variety of
financial and physical arrangements intended to support oil and natural gas
prices at targeted levels and to manage its exposure to oil and gas price
fluctuations. Apache may use futures contracts, swaps, options and fixed-price
physical contracts to hedge its commodity prices. Realized gains or losses from
the Company's price risk management activities are recognized in oil and gas

20
23

production revenues when the associated production occurs. Apache does not hold
or issue derivative instruments for trading purposes. In 1997, Apache recognized
a net gain of $1.4 million from hedging activities that increased oil and gas
production revenues. The net gain in 1997 includes $14.5 million in derivative
income and $13.1 million in losses on fixed price physical gas contracts. In
1996, Apache recognized a net loss from hedging activities of $23.8 million.
Gains or losses on natural gas derivative contracts are expected to be offset by
sales at the spot market price or to preserve the margin on existing physical
contracts. A 10 percent improvement in year-end spot market prices would
increase the fair value of derivative contracts in effect at December 31, 1997
by $21 million, while a 10 percent fall in spot prices would decrease the fair
value of these instruments by $21 million.

Hedging activity relative to oil production resulted in a $.1 million gain
in 1997. The Company did not have any open positions with respect to crude oil
hedging at December 31, 1997.

INTEREST RATE RISK

The Company considers its interest rate risk exposure minimal as a result
of fixing interest rates on over two-thirds of the Company's debt. Total debt at
December 31, 1997, included about $473 million of floating-rate debt. As a
result, Apache's annual interest costs in 1998 will fluctuate based on
short-term interest rates on approximately 31 percent of its total debt
outstanding at December 31, 1997. The impact on annual cash flow of a 10 percent
change in the floating rate (approximately 64 basis points) would be $3 million.

FOREIGN CURRENCY RISK

The Company's cash flow stream relating to certain international operations
is based on the U.S. dollar equivalent of cash flows measured in foreign
currencies. Australia gas production is sold under fixed-price Australian dollar
contracts and substantially all capital expenditures and operating costs are
paid in Australian dollars. Revenue and disbursement transactions denominated in
Australian dollars are converted to U.S. dollar equivalents based on the
exchange rate on the transaction date. Reported cash flow relating to Canadian
operations is based on cash flows measured in Canadian dollars converted to the
U.S. dollar equivalent based on the average of the Canadian and U.S. dollar
exchange rates for the period reported. Substantially all of the Company's
international transactions, outside of Canada and Australia, are denominated in
U.S. dollars.

The Company's Canadian and Australian subsidiaries have net financial
obligations that are denominated in a currency other than the functional
reporting currency of the subsidiaries. A decrease in value of 10 percent in the
Australian and Canadian dollars relative to the U.S. dollar from the year-end
exchange rates would result in a foreign currency loss of approximately $11
million, based on December 31, 1997 amounts. The Company considers its current
risk exposure to exchange rate movements, based on net cash flows, to be
immaterial. The Company did not have any open derivative contracts relating to
foreign currencies at December 31, 1997.

CASH FLOW, LIQUIDITY AND CAPITAL RESOURCES

CAPITAL COMMITMENTS

Apache's primary needs for cash are for exploration, development and
acquisition of oil and gas properties, repayment of principal and interest on
outstanding debt, payment of dividends, and capital obligations for affiliated
ventures. The Company funds its exploration and development activities through
internally generated cash flows. Apache budgets its capital expenditures based
upon projected cash flows. The Company routinely adjusts its capital
expenditures in response to changes in oil and natural gas prices and cash flow.
The Company cannot predict future product prices.

Expenditures for exploration and development totaled $685.4 million in 1997
compared to $493.7 million in 1996. Apache's drilling program in 1997 added
113.5 MMboe of reserves (including revisions) and replaced 183 percent of
production. In the United States, Apache completed 261 gross wells as producers
out of 318 gross wells drilled during the year, compared with 229 gross
producers out of 293 gross wells drilled in 1996. In Canada, Apache completed 60
gross wells as producers out of 81 gross wells drilled during the year, compared
with 50 gross producers out of 77 gross wells drilled in 1996.

Internationally, the Company completed 41 gross producers out of 73 gross
wells drilled in 1997, compared to 24 gross producers out of 36 gross wells in
1996. The international wells drilled in 1997 included 30 successful wells in
Egypt and nine successful wells in Australia.

The total capital expenditures budget for 1998 is $523.2 million. This
includes $274.0 million for North America. Estimated U.S. exploration and
development expenditures for 1998 are $227.8 million, which includes $122.6
million in the Gulf region, $70.0 million in the Midcontinent region and $35.2
million in the Western region. Apache expects to spend $46.2 million in Canada
in 1998. The Company expects its other international exploration and development
expenditures in 1998, exclusive of facilities, to total approximately $249.2
million.

On November 20, 1997, the Company, acquired all the capital stock of three
companies owning interests in certain oil and gas properties (including 31.9
MMboe of proved oil and natural gas reserves) and production facilities offshore
Western Australia for approximately $300 million pursuant to three agreements
with subsidiaries of Mobil. Funds for the Ampolex Group Transaction were
obtained principally from borrowings under the Company's global credit facility.

The Ampolex Group Transaction, net of the sale of certain properties to
Hardy Petroleum Limited (Hardy), increased the Company's interest to 47.5
percent from 22.5 percent in the Carnarvon Basin's Harriet area, which includes
the Varanus Island pipeline, processing and production complex and eight
existing oil and gas fields. In addition, the Company's interest in the East
Spar field, which produces through the Varanus Island facilities, increased to
45 percent from 20 percent. Apache operates the Harriet/East Spar Properties.

In conjunction with the closing of the Ampolex Group Transaction on
December 9, 1997, the Company entered into an agreement with Hardy under which
Hardy agreed to purchase a 10 percent interest in the Company's East Spar gas
field and related production facilities in Western Australia. The transaction
closed on January 28, 1998 with a total sales price of approximately $63 million
in cash.

In 1997, the Company also completed 45 tactical regional acquisitions for
cash consideration totaling $33.6 million. These acquisitions added
approximately 6.6 MMboe to the Company's reserves.

Cash expenditures for acquisitions of proved oil and gas properties during
1996 totaled $446.2 million compared to $820.9 million in 1995. The Company
added 52 MMboe of proved oil and gas reserves through

22
25

purchases in 1996. The most significant transaction completed in 1996 was the
merger with Phoenix. Apache acquired oil and gas properties totaling $331.2
million from Phoenix. Apache also acquired $115.0 million of other oil and gas
properties located primarily in the Company's existing focus areas. This amount
included the purchase of certain oil and gas properties from Hall-Houston for
$46 million in cash. Funds for the acquisitions were obtained principally from
borrowings under the Company's revolving bank credit facility.

On March 1, 1995, Apache purchased certain United States oil and gas
properties from Texaco for approximately $567 million in cash, subject to
adjustment. Funds for the Texaco transaction were obtained from several sources,
including increased borrowing capacity under the Company's revolving bank credit
facility and proceeds of Apache's $172.5 million 6-percent convertible
subordinated debentures due 2002 (6-percent debentures), which were issued on
January 4, 1995.

In September 1995, Apache acquired substantially all of the oil and natural
gas assets of Aquila for approximately $210 million. The oil and gas properties
included approximately 107,000 developed and 49,000 undeveloped net acres
located primarily in Apache's Anadarko Basin and Gulf of Mexico core areas. Also
included in the transaction was the purchase of a five-year, four-month
premium-price gas contract and interests in four gas processing plants.

Debt and Interest Commitments -- At December 31, 1997, Apache had
outstanding debt of $255 million under its global credit facility and an
aggregate of $1,263.6 million of other debt. This other debt included notes and
debentures maturing in the years 2000 through 2096. Debt outstanding at December
31, 1997 of $1.5 billion was up 23 percent over the $1.2 billion outstanding at
December 31, 1996. The increase reflects the Ampolex Group Transaction and other
1997 property acquisitions. The Company's debt-to-capitalization ratio increased
from 44.9 percent at December 31, 1996 to 46.8 percent at December 31, 1997.
Apache's debt-to-capitalization ratio for January 1998 fell below 42 percent due
in part to the conversion of 90 percent of the $172.5 million 6-percent
debentures into approximately 5.1 million shares of Apache common stock.
Interest payments on the Company's debt for 1998 are projected to be $116.2
million (using weighted average balances for floating rate obligations).
Scheduled principal payments for 1998 total $17.2 million.

Dividend Payments -- Dividends paid during 1997 totaled $25.3 million, up
eight percent from 1996, due to the increased number of shares outstanding. The
Company has paid cash dividends on its common stock for 124 consecutive quarters
through December 31, 1997, and expects to continue payment of dividends at
current levels. Future dividend payments will depend on the Company's level of
earnings, financial requirements and other relevant factors.

CAPITAL RESOURCES AND LIQUIDITY

The Company's primary capital resources are net cash provided by operating
activities, proceeds from financing activities and proceeds from sales of
non-strategic assets.

Net Cash Provided by Operating Activities -- Apache's net cash provided by
operating activities during 1997 totaled $723.8 million, an increase of 48
percent from the $490.5 million provided in 1996. This increase was due
primarily to higher oil and gas production and higher gas prices in 1997. The
receipt of $115.2 million from a purchaser as an advance also impacted 1997 net
cash provided by operating activities. This advance was for future natural gas
deliveries of 20,000 MMbtu per day over a ten-year period commencing September
1997. Net cash provided by operating activities in 1996 rose $158.4 million from
1995 primarily due to higher product prices.

Long-Term Borrowings -- In January 1997, the Company established a $300
million commercial paper program that allows Apache to borrow funds for up to
270 days at competitive interest rates. The commercial paper program is
supported by availability under the U.S. portion of Apache's global credit
facility. In June 1997, the Company expanded its commercial paper program to
$700 million from $300 million to provide access to additional low-cost,
short-term funds. Since its inception in January 1997, the commercial paper
program has been rated A-2, Prime-2 and D-1- (D-One-Minus) by Standard & Poor's
(S&P), Moody's and Duff and Phelps, respectively.

23
26

Also in January 1997, S&P upgraded the Company's senior long-term debt
rating from BBB to BBB+ and subordinated long-term debt rating from BBB- to BBB.
Apache was also named to the S&P 500 in 1997.

In June 1997, the Company replaced its $1 billion global borrowing-base
credit facility with a new $1 billion global credit facility that provides
Apache with greater borrowing capacity, increased financial flexibility and less
restrictive covenants, while lowering its all-in borrowing cost by 7 1/2 basis
points.

The global credit facility consists of three separate bank facilities: a
$700 million facility in the U.S.; a $175 million facility in Australia; and a
$125 million facility in Canada. The global credit facility enables Apache to
draw on the entire $1 billion facility without restrictions tied to periodic
revaluation of the Company's oil and gas reserves.

In August 1997, Apache issued $150 million principal amount, $148 million
net of discount, of senior unsecured 7.375-percent debentures maturing on August
15, 2047. The proceeds from this issuance were used to reduce the Company's
outstanding commercial paper obligations and for general corporate purposes.

The Company terminated two secured credit facilities with the IFC in
October 1997. This financing was replaced with a secured, revolving credit
facility that provides total commitments of $250 million and an initial
borrowing base of $150 million. This borrowing base will be redetermined
semi-annually. The total amount of commitments under the facility is currently
scheduled to be reduced by set increments every six months, beginning two and
one-half years after the effective date of the facility. The facility is
scheduled to mature on January 3, 2003.

In December 1997, Apache Finance Pty Ltd, an Australian finance subsidiary,
issued $170 million principal amount, $168.7 million net of discount, of 6.5
percent notes due on December 15, 2007. Apache irrevocably and unconditionally
guaranteed the notes, and has the right to redeem the notes prior to maturity,
subject to certain conditions. The proceeds from this issuance were used to
repay funds borrowed for the Ampolex Group Transaction and general corporate
purposes.

In February 1998, Apache issued $150 million principal amount, $148.2
million net of discount, of senior unsecured 7-percent notes maturing on
February 1, 2018. The notes are not redeemable prior to maturity. Net proceeds
from the sale were used to reduce existing short-term obligations and for
general corporate purposes.

Stock Transactions -- In November 1997, all the Company's 3.93-percent
convertible notes were converted into approximately 2.8 million shares of Apache
common stock. The notes were converted at a rate of 37.04 shares of common stock
per $1,000 principal amount.

In January 1998, approximately 90 percent, or $155.6 million, of the
Company's 6 percent debentures were converted into 5.1 million shares of Apache
common stock at a conversion rate of approximately 32.59 shares of common stock
per $1,000 principal amount. The remaining $16.9 million principal amount was
redeemed for $17.4 million in cash, plus accrued and unpaid interest.

Asset Sales -- Apache received $30.1 million in both 1997 and 1996 from the
sale of non-strategic oil and gas properties in a number of separate
transactions.

In January 1998, Apache closed the sale of a 10 percent interest in
Apache's East Spar gas field and related production facilities in Western
Australia for approximately $63 million in cash. Apache used the proceeds to
reduce outstanding loans under the Australian portion of the global credit
facility.

Liquidity -- The Company had $9.7 million in cash and cash equivalents on
hand at December 31, 1997, down from $13.2 million at December 31, 1996.
Apache's ratio of current assets to current liabilities increased from .87:1 at
December 31, 1996, to 1.01:1 at December 31, 1997.

Management believes that cash on hand, net cash generated from operations
and unused committed borrowing capacity under its global credit facility will be
adequate to satisfy the Company's financial obligations to meet future liquidity
needs for at least the next two fiscal years. As of December 31, 1997, Apache's
available borrowing capacity under its global credit facility was $694.2
million.

IMPACT OF THE YEAR 2000 ISSUE

The "Year 2000 Issue" is the result of computer software being written
using two digits rather than four to define the applicable year. Any of the
Company's computer programs that have date-sensitive software may recognize a
date using "00" as the year 1900 rather than the year 2000. If left
unremediated, this could result in a system failure or miscalculations causing
disruptions of operations, including, among other things, a temporary inability
to process transactions, send oil and gas revenue disbursement checks, or engage
in similar normal business activities.

The Company is in the process of replacing significant portions of its
software to more effectively and efficiently meet its business needs.
Replacement computer systems selected by the Company will properly recognize
dates beyond December 31, 1999. The Company presently believes that with
conversions to new software, the Year 2000 Issue will be eliminated. However, if
such conversions are not made, or are not completed timely, the Year 2000 Issue
could have a material impact on the operations of the Company. The Company plans
to replace substantially all of its existing systems within 15 months or not
later than March 31, 1999.

The date on which the Company plans to complete installation of its new
system is based on management's best estimates, which were derived using
numerous assumptions of future events including the continued availability of
certain resources. However, there can be no guarantee that these estimates will
be achieved and actual results could differ materially from those plans.
Specific factors that might cause such material differences include, but are not
limited to, the availability and cost of personnel trained in this area, and
similar uncertainties.

FUTURE TRENDS

Apache's strategy is to increase its oil and gas reserves, production and
cash flow by continuing to explore on and develop its inventory of existing
projects and making carefully targeted acquisitions of new assets. Robust oil
and gas prices early in 1997 gave way to weaker prices later in the year and on
into 1998. Crude oil prices have fallen near their lowest level of the 1990's.
While lower prices are expected to negatively impact Apache's 1998 earnings and
cash from operations (see, "Market Risk-Commodity Risk" above and "Item 1.
Business -- Oil and Natural Gas Prices," "Full Cost Center Ceiling Test,"
"Reserves; Rates of Production; Development Expenditures; Cash Flow," and
"Effect of Volatile Prices"), Apache has taken steps to improve its financial
liquidity for the purpose of better positioning the company to fund potential
opportunities that might result from industry adversity. Specific actions that
may be or have been taken which should impact the Company's activities in 1998
and beyond include:

(1) Selling and trading non-strategic properties to upgrade the Company's
property portfolio and reduce debt.

(2) Curtailing projected exploration and development expenditures to remain
within cash from operations.

(3) Calling for redemption of $175 million of debentures of which 90 percent or
$156 million were converted to equity in January 1998.

The above steps should strengthen Apache's financial position and add
liquidity. Should property acquisition prices fall from the premium price
commanded in 1997 to what management believes to be more reasonable levels,
Apache may seek to undertake a significant acquisition. Alternatively, if
drilling costs retreat further from the levels to which they rose in 1997,
Apache may expand its drilling activity. In either event, Apache expects to
review the level of its capital expenditures quarterly in light of financial
results, product prices, drilling costs and prevailing industry conditions. Even
at a reduced capital expenditure level, Apache expects to remain an active
operator in North America drilling moderate-risk wells.

Apache's international properties should continue to grow in importance
with respect to Apache's financial results and future growth prospects. Apache's
international efforts in the coming year will be focused on development of its
discoveries in Egypt, offshore Western Australia, offshore The People's Republic
of China and offshore the Ivory Coast, and exploration efforts on the Company's
concessions in Egypt and its new properties in Poland. While international
exploration is recognized as higher risk than Apache's North

25
28

American activities, the Company believes it offers potential for greater
rewards and significant reserve additions. Apache also believes that reserve
additions in these international areas may be made through higher risk
exploration and through improved production practices and recovery techniques.

FORWARD-LOOKING STATEMENTS AND RISK

Certain statements in this report, including statements of the future
plans, objectives, and expected performance of the Company, are forward-looking
statements that are dependent on certain events, risks and uncertainties that
may be outside the Company's control which could cause actual results to differ
materially from those anticipated. Some of these include, but are not limited
to, economic and competitive conditions, inflation rates, legislative and
regulatory changes, financial market conditions, political and economic
uncertainties of foreign governments, future business decisions, and other
uncertainties, all of which are difficult to predict.

There are numerous uncertainties inherent in estimating quantities of
proved oil and gas reserves and in projecting future rates of production and
timing of development expenditures. The total amount or timing of actual future
production may vary significantly from reserves and production estimates. The
drilling of exploratory wells can involve significant risks including those
related to timing, success rates and cost overruns. Lease and rig availability,
complex geology and other factors can affect these risks. Future oil and gas
prices also could affect results of operations and cash flows. Although Apache
makes use of futures contracts, swaps, options and fixed-price physical
contracts to mitigate risk, fluctuations in oil and gas prices may affect the
Company's financial position and results of operations.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To The Shareholders of Apache Corporation:

We have audited the accompanying consolidated balance sheet of Apache
Corporation (a Delaware corporation) and Subsidiaries as of December 31, 1997
and 1996, and the related statements of consolidated income, shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1997. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Apache
Corporation and Subsidiaries as of December 31, 1997 and 1996, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted accounting
principles.

REPORT OF MANAGEMENT

The financial statements and related financial information of Apache
Corporation and Subsidiaries were prepared by and are the responsibility of
management. The statements have been prepared in conformity with generally
accepted accounting principles and include amounts that are based on
management's best estimates and judgments.

Management maintains and places reliance on systems of internal control
designed to provide reasonable assurance, weighing the costs with the benefits
sought, that all transactions are properly recorded in the Company's books and
records, that policies and procedures are adhered to, and that assets are
safeguarded. The systems of internal controls are supported by written policies
and guidelines, internal audits and the selection and training of qualified
personnel.

The consolidated financial statements of Apache Corporation and
Subsidiaries have been audited by Arthur Andersen LLP, independent public
accountants. Their audits included developing an overall understanding of the
Company's accounting systems, procedures and internal controls and conducting
tests and other auditing procedures sufficient to support their opinion on the
fairness of the consolidated financial statements.

The Apache Corporation Board of Directors exercises its oversight
responsibility for the financial statements through its Audit Committee,
composed solely of directors who are not current or former employees of Apache.
The Audit Committee meets periodically with management, internal auditors and
the independent public accountants to ensure that they are successfully
completing designated responsibilities. The internal auditors and independent
public accountants have open access to the Audit Committee to discuss auditing
and financial reporting issues.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations -- Apache Corporation (Apache or the Company) is an
independent energy company that explores for, develops and produces natural gas,
crude oil and natural gas liquids. The Company's North American exploration and
production activities are divided into four U.S. operating regions (Offshore,
Midcontinent, Gulf Coast and Western), plus a Canadian region. Approximately 72
percent of the Company's proved reserves are located in North America.
Internationally, Apache has exploration and production interests offshore
Western Australia and in Egypt, and exploration interests in Poland, offshore
The People's Republic of China, offshore the Ivory Coast and in Indonesia.
Apache treats all operations as one segment of business.

The Company's future financial condition and results of operations will
depend upon prices received for its oil and natural gas production and the costs
of finding, acquiring, developing and producing reserves. A substantial portion
of the Company's production is sold under market-sensitive contracts. Prices for
oil and natural gas are subject to fluctuations in response to changes in
supply, market uncertainty and a variety of other factors beyond the Company's
control. These factors include worldwide political instability (especially in
the Middle East), the foreign supply of oil and natural gas, the price of
foreign imports, the level of consumer demand, and the price and availability of
alternative fuels. With natural gas accounting for 60 percent of Apache's 1997
production on an energy equivalent basis, the Company is affected more by
fluctuations in natural gas prices than in oil prices.

Principles of Consolidation -- The accompanying consolidated financial
statements include the accounts of Apache and its subsidiaries after elimination
of intercompany balances and transactions. The Company's interests in oil and
gas ventures and partnerships are proportionately consolidated. Apache's
investment in Producers Energy Marketing LLC (ProEnergy), a jointly-owned
natural gas marketing company, is accounted for using the equity method.

Cash Equivalents -- The Company considers all highly liquid debt
instruments purchased with an original maturity of three months or less to be
cash equivalents. These investments are carried at cost, which approximates
market.

Inventories -- Inventories consist principally of tubular goods and
production equipment, stated at the lower of weighted average cost or market,
and oil produced but not sold, stated at current market value net of costs to
sell.

Property and Equipment -- The Company uses the full cost method of
accounting for its investment in oil and gas properties. Under this method, the
Company capitalizes all acquisition, exploration and development costs incurred
for the purpose of finding oil and gas reserves, including salaries, benefits
and other internal costs directly attributable to these activities. Exclusive of
field-level costs, Apache capitalized $11.9 million, $12.1 million and $12.5
million of internal costs in 1997, 1996 and 1995, respectively. Costs associated
with production and general corporate activities are expensed in the period
incurred. Internal costs attributable to the management of the Company's
producing properties, before recoveries from industry partners, totaled $22.5
million, $17.0 million and $16.3 million in 1997, 1996, and 1995, respectively,
and are included in operating costs in the Company's statement of consolidated
income. Interest costs related to unproved properties and properties under
development are also capitalized to oil and gas properties. Unless a significant
portion of the Company's reserve volumes are sold (greater than 25 percent),
proceeds from the sale of oil and gas properties are accounted for as reductions
to capitalized costs, and gains and losses are not recognized.

Apache computes the provision for depreciation, depletion and amortization
(DD&A) of oil and gas properties on a quarterly basis using the
unit-of-production method based upon production and estimates of proved reserve
quantities. Unevaluated costs and related capitalized interest costs are
excluded from the amortization base until the properties associated with these
costs are evaluated. The amortizable base includes
F-7
44
APACHE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

estimated future development costs and dismantlement, restoration and
abandonment costs, net of estimated salvage values. These future costs are
generally estimated by engineers employed by Apache.

Apache limits, on a country-by-country basis, the capitalized costs of oil
and gas properties, net of accumulated DD&A and deferred income taxes, to the
estimated future net cash flows from proved oil and gas reserves discounted at
10 percent, net of related tax effects, plus the lower of cost or fair value of
unproved properties included in the costs being amortized. If capitalized costs
exceed this limit, the excess is charged to nonrecurring DD&A expense. Included
in the estimated future net cash flows are Canadian provincial tax credits
expected to be realized beyond the date at which the legislation, under its
provisions, could be repealed. To date, the Canadian provincial government has
not indicated an intention to repeal this legislation.

The costs of certain unevaluated leasehold acreage, wells being drilled and
international concession rights are not being amortized. Costs not being
amortized are periodically assessed for possible impairments or reductions in
value. If a reduction in value has occurred, costs being amortized are increased
or a charge is made against earnings for those international operations where a
reserve base is not yet established.

Buildings, equipment and gas gathering, transmission and processing
facilities are depreciated on a straight-line basis over the estimated useful
lives of the assets, which range from two to 15 years. Accumulated depreciation
for these assets totaled $51.8 million and $36.6 million at December 31, 1997
and 1996, respectively.

Accounts Payable -- Included in accounts payable at December 31, 1997 and
1996, are liabilities of approximately $36.3 million and $36.5 million,
respectively, representing the amount by which checks issued, but not presented
to the Company's banks for collection, exceeded balances in applicable bank
accounts.

Revenue Recognition -- Apache uses the sales method of accounting for
natural gas revenues. Under this method, revenues are recognized based on actual
volumes of gas sold to purchasers. The volumes of gas sold may differ from the
volumes to which Apache is entitled based on its interests in the properties.
Differences between volumes sold and entitled volumes create gas imbalances
which are generally reflected as adjustments to reported gas reserves and future
cash flows in the Company's supplemental oil and gas disclosures. Adjustments
for gas imbalances totaled approximately one percent of Apache's proved gas
reserves at December 31, 1997. Revenue is deferred and a liability is recorded
for those properties where the estimated remaining reserves will not be
sufficient to enable the underproduced owner to recoup its entitled share
through production.

Hedging Activities -- Apache periodically enters into commodity derivatives
contracts and fixed-price physical contracts to manage its exposure to oil and
gas price volatility. Commodity derivatives contracts, which are usually placed
with major financial institutions that the Company believes are minimal credit
risks, may take the form of futures contracts, swaps or options. The oil and gas
reference prices upon which these commodity derivatives contracts are based
reflect various market indices that have a high degree of historical correlation
with actual prices received by the Company. The Company accounts for its
commodity derivatives contracts using the hedge (or deferral) method of
accounting. Under this method, realized gains and losses from the Company's
price risk management activities are recognized in oil and gas production
revenues when the associated production occurs and the resulting cash flows are
reported as cash flows from operating activities. Gains and losses on commodity
derivatives contracts that are closed before the hedged production occurs are
deferred until the production month originally hedged. In the event of a loss of
correlation between changes in oil and gas reference prices under a commodity
derivatives contract and actual oil and gas prices, a gain or loss is recognized
currently to the extent the commodity derivatives contract has not offset
changes in actual oil and gas prices.

Income Taxes -- The Company follows the liability method of accounting for
income taxes under which deferred tax assets and liabilities are recognized for
the future tax consequences of (i) temporary differences between the tax bases
of assets and liabilities and their reported amounts in the financial statements
and
F-8
45
APACHE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

(ii) operating loss and tax credit carryforwards for tax purposes. Deferred tax
assets are reduced by a valuation allowance when, based upon management's
estimates, it is more likely than not that a portion of the deferred tax assets
will not be realized in a future period.

Foreign Currency Translation -- The U.S. dollar is considered the
functional currency for each of the Company's international operations, except
for its Canadian subsidiary whose functional currency is the Canadian dollar.
Translation adjustments resulting from translating the Canadian subsidiary's
foreign currency financial statements into U.S. dollar equivalents are reported
separately and accumulated in a separate component of shareholders' equity. For
other international operations, transaction gains or losses are recognized in
net income.

Net Income Per Common Share -- Basic and diluted net income per common
share have been computed in accordance with Statement of Financial Accounting
Standards (SFAS) No. 128, "Earnings per Share," which the Company adopted at
year-end 1997. Net income per share amounts for prior periods have been restated
to conform with the provisions of the new standard. Basic net income per common
share is computed by dividing income available to common shareholders by the
weighted average number of common shares outstanding for the period. Diluted net
income per common share reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock. Calculations of basic and diluted net income per common share
are illustrated in Note 7.

Stock-Based Compensation -- The Company accounts for employee stock-based
compensation using the intrinsic value method prescribed by Accounting
Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to
Employees" and related Interpretations. Nonemployee stock-based compensation is
accounted for using the fair value method in accordance with SFAS No. 123,
"Accounting for Stock-Based Compensation."

Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
Significant estimates with regard to these financial statements include the
estimate of proved oil and gas reserve volumes and the related present value of
estimated future net cash flows therefrom (see supplemental oil and gas
disclosures).

2. ACQUISITIONS AND DIVESTITURES

ACQUISITIONS

On November 20, 1997, the Company acquired all the capital stock of three
companies owning interests in certain oil and gas properties (including 31.9
MMboe of proved oil and natural gas reserves) and production facilities offshore
Western Australia for approximately $300 million from subsidiaries of Mobil
Exploration & Producing Australia Pty Ltd (Ampolex Group Transaction). The
Ampolex Group Transaction, net of the sale of certain properties to Hardy
Petroleum Limited (Hardy), increased the Company's interest to 47.5 percent from
22.5 percent in the Carnarvon Basin's Harriet area, which includes the Varanus
Island pipeline, processing and production complex and eight existing oil and
gas fields. The transaction also increased the Company's interest in the East
Spar field, which produces through the Varanus Island facilities, to 45 percent
from 20 percent. Apache operates the Harriet and East Spar properties.

========


In conjunction with the closing of the Ampolex Group Transaction, the
Company entered into an agreement with Hardy on December 9, 1997, under which
Hardy agreed to purchase a 10 percent interest in the Company's East Spar field
and related production facilities. The transaction closed on January 28, 1998,
with a total sales price of approximately $63 million in cash. The assets sold
to Hardy are reported as assets held for resale in the accompanying consolidated
balance sheet.

In 1997, the Company also completed 45 tactical regional acquisitions for
cash consideration totaling $33.6 million. These acquisitions added
approximately 6.6 MMboe to the Company's reserves.

On May 20, 1996, Apache acquired, for approximately $396.3 million, The
Phoenix Resource Companies, Inc. (Phoenix, now known as Apache PHN Company,
Inc.), an oil and gas company operating primarily in the Arab Republic of Egypt,
through a merger (Merger) which resulted in Phoenix becoming a wholly owned
subsidiary of Apache. Pursuant to the Merger Agreement, shares of Phoenix common
stock then outstanding and outstanding Phoenix stock options (which were assumed
by Apache) were converted into the right to receive (a) .75 shares of Apache
common stock with any fractional shares paid in cash, without interest, and (b)
$4.00 in cash. As a result, 12.2 million shares of Apache common stock, valued
at $26 per share, were issued and approximately $65 million was paid to former
Phoenix shareholders.

In 1996, the Company also completed 62 tactical regional acquisitions for
cash consideration totaling $115.0 million. These acquisitions added
approximately 18.9 MMboe to the Company's reserves.

In September 1995, Apache acquired substantially all the oil and gas assets
of Aquila Energy Resources Corporation (Aquila) for approximately $210 million.
The acquired assets included proved reserves totaling an estimated 157 Bcf of
gas equivalent, approximately 107,000 developed and 49,000 undeveloped net acres
located primarily in Apache's Anadarko Basin and Gulf of Mexico core areas, a
five-year, four-month premium-price gas contract effective September 1, 1995,
and non-operated interests in four gas processing plants. The gas contract calls
for Aquila Energy Marketing Corporation, a wholly owned subsidiary of UtiliCorp
United Inc., to purchase 20 to 25 MMcf of gas per day from Apache at a price of
$2.70 per Mcf in 1996, escalating to $3.20 per Mcf in the year 2000.

On May 17, 1995, Apache acquired DEKALB Energy Company (DEKALB, now known
as DEK Energy Company), an oil and gas company engaged in the exploration for,
and the development of, crude oil and natural gas in Canada, through a merger
which resulted in DEKALB becoming a wholly owned subsidiary of Apache. Pursuant
to the merger agreement, 8.4 million shares of Apache common stock were
exchanged for the outstanding DEKALB stock and DEKALB employee stock options.
Merger costs of approximately $10 million were charged to expense in 1995. The
merger was accounted for as a "pooling of interests" and, as a result, the
Company's consolidated financial statements for periods prior to the merger have
been restated to include combined results with DEKALB.

On March 1, 1995, Apache completed the acquisition of 315 oil and gas
fields from Texaco Exploration and Production Inc. (Texaco) for an adjusted
purchase price of approximately $567 million. The Texaco

properties included estimated proved reserves at the effective date, after
adjustment for the exercise of preferential rights and properties excluded
following due diligence, of approximately 105 MMboe.

Except for the DEKALB transaction, each transaction described above has
been accounted for using the purchase method of accounting and has been included
in the financial statements of Apache since the date of acquisition.

The following unaudited pro forma financial information shows the effect on
the Company's consolidated results of operations as if the Phoenix Merger
occurred on January 1, 1996. The pro forma data is based on numerous assumptions
and is not necessarily indicative of future results of operations.

DIVESTITURES

Apache received $30.1 million in each of 1997 and 1996 from the sale of
non-strategic oil and gas properties in a number of separate transactions.

In September 1995, Apache closed the sale of non-strategic oil and gas
properties in its Rocky Mountain region for approximately $140 million net to
Apache. The assets included Apache's interests in 138 fields with approximately
1,600 active wells in Colorado, Montana, North and South Dakota, Utah and
Wyoming. The Company retained its interests in the Green River Basin of Colorado
and Wyoming and in the San Juan Basin of Colorado and New Mexico. Proceeds from
the sale of all oil and gas properties sold during 1995 totaled $271.9 million.

3. INVESTMENTS IN EQUITY SECURITIES

At December 31, 1997 and 1996, Apache had no investments in equity
securities.

The Company realized gains totaling approximately $13,000, $770,000 and
$906,000 from the sale of equity securities during 1997, 1996 and 1995,
respectively. Apache utilizes the average cost method in computing realized
gains or losses, which are included in other revenues in the accompanying
statement of consolidated income.

On June 12, 1997, Apache replaced its $1 billion global borrowing-base
credit facility with a new $1 billion global corporate credit facility (global
credit facility). The global credit facility consists of three separate bank
facilities: a $700 million facility in the United States; a $175 million
facility in Australia; and a $125 million facility in Canada. The global credit
facility enables Apache to draw on the entire $1 billion facility without
restrictions tied to periodic revaluation of the Company's oil and gas reserves.
As of December 31, 1997, Apache's available borrowing capacity under the global
credit facility was $694.2 million. Under the financial covenants of the global
credit facility, the Company must (i) maintain a consolidated tangible net
worth, as defined, of at least $1.051 billion as of December 31, 1997, which is
adjusted for subsequent earnings, and (ii) maintain a ratio of debt to
capitalization of not greater than 60 percent at the end of any fiscal quarter.
The Company was in compliance with all financial covenants at December 31, 1997.

The global credit facility is scheduled to mature on June 12, 2002, and the
agreement provides for perpetual one-year extensions as requested by the
Company, subject to the approval of the lenders. At the Company's option, the
interest rate is based on (i) the greater of (a) The Chase Manhattan Bank's
prime rate or (b) the federal funds rate plus one-half of one percent, (ii) the
London Interbank Offered Rate (LIBOR) plus a margin determined by the Company's
senior long-term debt rating, or (iii) a margin that is determined by
competitive bids from the participating banks. At December 31, 1997, the margin
over LIBOR for committed loans was .185 percent. The Company also pays a
quarterly facility fee of .09 percent on the total

F-12
49
APACHE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

amount of each of the three facilities, which fee varies based upon the
Company's senior long-term debt rating.

In January 1997, Standard & Poor's upgraded the Company's senior long-term
debt rating from BBB to BBB+ and subordinated long-term debt rating from BBB- to
BBB.

In January 1997, the Company established a $300 million commercial paper
program which allows Apache to borrow funds for up to 270 days at competitive
interest rates. In June 1997, the Company expanded its commercial paper program
to $700 million from $300 million to provide access to additional low-cost,
short-term funds. Since its inception in January 1997, the commercial paper
program has been rated A-2, Prime-2 and D-1- (D-One-Minus) by Standard & Poor's,
Moody's and Duff and Phelps, respectively. As of December 31, 1997, $50.8
million was outstanding under Apache's commercial paper program. The commercial
paper is classified as long-term debt in the accompanying consolidated balance
sheet as the Company has the ability and intent to refinance such amounts on a
long-term basis through either the rollover of commercial paper or available
borrowing capacity under the global credit facility.

In February 1996, Apache issued $100 million principal amount, $99.6
million net of discount, of senior unsecured 7.7-percent notes due March 15,
2026. In April 1996, the Company issued $180 million principal amount, $178.5
million net of discount, of senior unsecured 7.95-percent notes maturing on
April 15, 2026. Additionally, in November 1996, Apache issued $150 million
principal amount, $149.2 million net of discount, of senior unsecured
7.625-percent debentures maturing on November 1, 2096. None of these instruments
are redeemable prior to maturity; however, under certain conditions, Apache has
the right to advance maturity of the above-referenced debentures.

In August 1997, Apache issued $150 million principal amount, $148.0 million
net of discount, of senior unsecured 7.375-percent debentures maturing on August
15, 2047. The debentures are not redeemable prior to maturity; however, Apache
has the right to advance maturity, under certain conditions.

The 9.25-percent notes totaling $100 million were issued by Apache in May
1992 and are not redeemable prior to their maturity in June 2002. Upon certain
changes in control of the Company, these notes are subject to mandatory
repurchase.

In November 1997, the Company's 3.93-percent convertible notes were
converted into approximately 2.8 million shares of Apache common stock at a
conversion price of $27 per share.

At December 31, 1997, the Company also had certain uncommitted money market
lines of credit which are used from time to time for working capital purposes.
As of December 31, 1997, an aggregate of $17.2 million was outstanding under
such credit lines.

In December 1997, Apache Finance Pty Ltd, (Apache Finance), an Australian
finance subsidiary of the Company, issued $170 million principal amount, $168.7
million net of discount, of senior unsecured 6.5-percent notes due December 15,
2007. The notes are irrevocably and unconditionally guaranteed by Apache. The
Company has the right to redeem the notes prior to maturity, under certain
conditions.

On October 30, 1997, three of the Company's Egyptian subsidiaries entered
into a secured, revolving credit facility with a group of banks. The facility
provides for total commitments of $250 million, with availability determined by
a borrowing base formula. The initial borrowing base was set at $150 million and
will be redetermined semi-annually. The total amount of commitments under the
facility is currently scheduled to be reduced by set increments every six
months, beginning two and one-half years after the effective date of the
facility. The facility is presently secured solely by assets associated with the
Company's Qarun and Khalda concessions and shares of stock of the Company's
subsidiaries holding said concessions, with provisions that will permit the
inclusion of other of the Company's Egyptian subsidiaries as borrowers with
security interests on such subsidiaries' assets and shares of stock. Interest is
assessed at LIBOR plus a margin of .375 percent, which is scheduled to increase
to .625 percent on the third anniversary of the facility;
F-13
50
APACHE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

however, if the facility is extended the rate increase would occur two years
from the end of the facility's extended term. A quarterly fee of .375 percent is
payable on the available portion of the commitments, while a quarterly fee of
.1875 percent is payable on the difference between the borrowing base and the
total amount of commitments under the facility. The facility is scheduled to
mature on January 3, 2003.

In October 1997, the Company provided funds to two of its Egyptian
subsidiaries to repay all amounts outstanding under two secured credit
facilities with the International Finance Corporation (IFC), which were
terminated.

The DEKALB 9.875-percent notes mature on July 15, 2000 and are not
redeemable prior to their maturity.

As of December 31, 1997 and 1996, the Company had approximately $18.2
million and $20.3 million, respectively, of unamortized costs associated with
its various debt obligations. These costs are reflected as deferred charges in
the accompanying consolidated balance sheet and are being amortized over the
life of the related debt.

In January 1998, approximately 90 percent, or $155.6 million, of the
Company's 6-percent convertible subordinated debentures was converted into
approximately 5.1 million shares of Apache common stock at a conversion price of
$30.68 per share. The remaining $16.9 million of principal amount was redeemed
for $17.4 million in cash, plus accrued and unpaid interest. The Company
recorded a $.8 million loss on the early extinguishment of debt in January 1998.

In February 1998, Apache issued $150 million principal amount, $148.2
million net of discount, of senior unsecured 7-percent notes maturing on
February 1, 2018. The notes are not redeemable prior to maturity.

The indentures for the notes and debentures described above place certain
restrictions on the Company, including limits on Apache's ability to incur debt
secured by certain liens and its ability to enter into certain sale and
leaseback transactions.

U.S. deferred taxes have not been provided on foreign earnings totaling
$151.4 million, which are permanently reinvested abroad. Presently, limited
foreign tax credits are available to reduce the U.S. taxes on such amounts if
repatriated.

At December 31, 1997, the Company had U.S. federal net operating loss
carryforwards of $170.4 million that will expire beginning in 1998, foreign net
operating loss carryforwards of $53.7 million that can be carried forward
indefinitely, and U.S. and foreign statutory depletion carryforwards totaling
$8.8 million that can be carried forward indefinitely. The Company has
alternative minimum tax (AMT) credit carryforwards of $9.1 million that can be
carried forward indefinitely, but which can be used only to reduce regular tax
liabilities in excess of AMT liabilities. The Company has investment and other
tax credit carryforwards of $1.7 million that will expire beginning in 1998,
which have been fully reserved through the valuation allowance.

6. ADVANCES FROM GAS PURCHASER

In August 1997, Apache received $115.2 million from a purchaser as an
advance payment for future natural gas deliveries of 20,000 MMBtu per day over a
ten-year period commencing September 1997. As a condition of the arrangement
with the purchaser, Apache entered into two gas price swap contracts with a
third party under which Apache became a fixed price payor for identical volumes
at average prices starting at $2.19 per MMBtu in 1997 and escalating to $2.59
per MMBtu in 2007. In addition, the purchaser pays Apache a monthly fee of $.07
per MMBtu on the contracted volumes. The net result of these related
transactions is that gas delivered to the purchaser is reported as revenue at
prevailing spot prices with Apache realizing a premium associated with the
monthly fee paid by the purchaser.

In December 1994, Apache received $67.4 million from a purchaser as an
advance payment for future natural gas deliveries of 20,000 MMBtu per day over a
six-year period commencing January 1995. As a condition of the arrangement with
the purchaser, Apache entered into a gas price swap contract with a third party
under which Apache became a fixed price payor for identical volumes at prices
starting at $1.81 per MMBtu in 1995 and escalating at $.10 per MMBtu per year
through the year 2000. The net result of these related transactions is that gas
delivered to the purchaser is reported as revenue at prevailing spot prices with
Apache realizing a $.05 per MMBtu premium associated with a monthly fee paid by
the purchaser.

The Company, through its marketing subsidiaries, may purchase gas from
third parties to satisfy gas delivery requirements under these arrangements.
Contracted volumes relating to these arrangements are included in the Company's
supplemental oil and gas disclosures.

These advance payments have been classified as advances on the balance
sheet and are being reduced as gas is delivered to the purchasers under the
terms of the contracts. At December 31, 1997 and 1996, advances of $154.5
million and $51.8 million, respectively, were still outstanding. Gas volumes
delivered to the purchaser are reported as revenue at prices used to calculate
the amount advanced, before imputed interest, minus or plus amounts paid or
received by Apache applicable to the price swap agreements. Interest expense is
recorded based on a rate of 8 percent and 9.5 percent on the 1997 and 1994
advances, respectively.

The 3.93-percent convertible notes and 6-percent convertible subordinated
debentures were not included in the computation of diluted net income per common
share during 1995, because to do so would have been antidilutive.

Stock Option Plans -- At December 31, 1997, officers and certain key
employees have been granted options to purchase the Company's common stock under
employee stock option plans adopted in 1990 and 1995 and under certain
predecessor plans (collectively, the Stock Option Plans). Under the Stock Option
Plans, the exercise price of each option equals the market price of Apache's
common stock on the date of grant. Options generally become exercisable ratably
over a four-year period and expire after 10 years. The Company may issue up to
4,007,006 shares of common stock under the Stock Option Plans, of which options
to acquire 411,775 shares of common stock remained available for grant at
December 31, 1997.

On October 31, 1996, the Company established the 1996 Performance Stock
Option Plan (the Performance Plan) for substantially all full-time employees,
excluding officers and certain key employees. Under the Performance Plan, the
exercise price of each option equals the market price of Apache common stock on
the date of grant. All options become exercisable after nine and one-half years
and expire ten years from the date of grant; however, exercisability will be
accelerated if share price goals of $50 and $60 per share,

respectively, are attained before January 1, 2000. The Company may issue up to

acquire 191,216 shares of common stock remained available for grant at December
31, 1997.

In May 1997, Apache's shareholders approved the 1996 Share Price
Appreciation Plan (the Appreciation Plan) for officers and certain key
employees. The Appreciation Plan provides for conditional grants denominated in
shares of Apache common stock that vest upon attainment of share price goals of
$50 and $60 per share, respectively, before January 1, 2000. Between 30 and 50
percent of the conditional grants will be paid in cash at the market value of
the stock on the date of payment, and the balance (up to a total of 2,000,000
shares in the aggregate) will be issued in Apache common stock. Generally, any
vested amounts will be distributed in three installments over the 36-month
period following attainment of the share price goals. When and if the share
price goals are achieved, the Company will recognize compensation expense over
the 36-month period equal to the value of the stock as of the date the share
price goal is achieved (i.e., $50 or $60 per share, as appropriate) and the
actual amount of cash paid. The shares of Apache common stock contingently
issuable under the Appreciation Plan will be excluded from the computation of
net income per common share until the stated share price goals of $50 and $60
per share are achieved.

A summary of the status of the Appreciation Plan as of December 31, 1997,
and changes during the year then ended, is presented in the table and narrative

The Company accounts for its stock-based compensation plans under APB
Opinion No. 25 and related interpretations, under which no compensation cost has
been recognized for the Stock Option Plans, the Performance Plan, or the
Appreciation Plan. If compensation costs for these plans had been determined in
accordance with SFAS No. 123, the Company's net income and net income per common
share would approximate the following pro forma amounts:

The pro forma amounts shown above may not be representative of future
results, as the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995.

Preferred Stock -- The Company has five million shares of no par preferred
stock authorized, of which 25,000 shares have been "designated" Series A Junior
Participating Preferred Stock and authorized for issuance pursuant to certain
rights that trade with Apache common stock outstanding. There are no shares of
preferred stock issued and outstanding; however, shares of preferred stock are
reserved for issuance upon the exercise of the preferred stock purchase rights
discussed below.

Rights to Purchase Preferred Stock -- In December 1995, the Company
declared a dividend of one right (a Right) for each share of Apache common stock
outstanding on January 31, 1996. Each Right entitles the registered holder to
purchase from the Company one ten-thousandth (1/10,000) of a share of Series A
Junior Participating Preferred Stock at a price of $100 per one ten-thousandth
of a share, subject to adjustment. The Rights are exercisable 10 calendar days
following a public announcement that certain persons or groups have acquired 20
percent or more of the outstanding shares of Apache common stock or 10 business
days following commencement of an offer for 30 percent or more of the
outstanding shares of Apache common stock. In addition, if the Company engages
in certain business combinations or a 20 percent shareholder engages in certain
transactions with the Company, the Rights become exercisable for Apache common
stock or common stock of the corporation acquiring the Company (as the case may
be) at 50 percent of the then-market price. Any Rights that are or were
beneficially owned by a person who has acquired 20 percent or more of the
outstanding shares of Apache common stock and who engages in certain
transactions or realizes the benefits of certain transactions with the Company
will become void. The Company may redeem the Rights at $.01 per Right at any
time until 10 business days after public announcement that a person has acquired
20 percent or more of the outstanding shares of Apache common stock. The Rights
will expire on January 31, 2006, unless earlier redeemed by the Company. Unless
the Rights have been previously redeemed, all shares of Apache common stock
issued by the Company after January 31, 1996 will include Rights. Unless and
until the Rights become exercisable, they will be transferred with and only with
the shares of Apache common stock.

APACHE CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

The following methods and assumptions were used to estimate the fair value
of the financial instruments summarized in the table above. The carrying values
of trade receivables and trade payables included in the accompanying
consolidated balance sheet approximated market value at December 31, 1997 and
1996.

Cash and Cash Equivalents -- The carrying amounts approximated fair value
due to the short maturity of these instruments.

Long-Term Debt -- The fair values of the 7.95-percent, 7.7-percent,
9.25-percent, 9.875-percent and 6.5-percent notes and the 7.375-percent
debentures are based on the quoted market prices for those issues. The fair
values of the 7.625-percent debentures, the 6-percent convertible subordinated
debentures and the 3.93-percent convertible notes are based upon estimates
provided to the Company by independent investment banking firms. The carrying
amount of the bank debt, commercial paper and money market lines of credit
approximates fair value because the interest rates are variable and reflective
of market rates.

Commodity Price Hedges -- Apache periodically enters into commodity
derivative contracts and fixed-price physical contracts to manage its exposure
to oil and gas price volatility. Commodity derivatives contracts, which are
usually placed with major financial institutions that the Company believes are
minimal credit risks, may take the form of futures contracts, swaps or options.
The derivative contracts call for Apache to receive, or make, payments based
upon the differential between a fixed and a variable commodity price as
specified in the contract. As a result of these activities, Apache recognized
hedging gains of $14.5 million in 1997 and hedging losses in 1996 and 1995 of
$23.0 million and $4.3 million, respectively. The 1997 hedging gain and the 1996
and 1995 hedging losses are included in oil and gas production revenues in the
statement of consolidated income.

The 1995 loss reflected a $9.3 million pre-tax charge to earnings resulting
from the loss of correlation of New York Mercantile Exchange (NYMEX) prices from
actual wellhead prices for certain positions in January through March 1996
production, reported as a reduction of other revenues, offset by $5 million of
commodity pricing gains which increased 1995 oil and gas production revenues.

Apache's consolidated balance sheet includes deferred credits totaling $2.2
million and $3.2 million at December 31, 1997 and 1996, respectively, for gains
realized on the early termination of commodity derivative contracts in 1997 and
prior years. These gains will be recognized as oil and gas production revenues
over periods ranging from one to 24 months as the hedged production occurs.

The following table and notes thereto cover the Company's pricing and
notional volumes on open natural gas commodity derivative contracts as of
December 31, 1997:



1998 1999 2000 2001 2002 THEREAFTER
----- ----- ----- ----- ----- ----------

Average swap price, per MMBtu(1)......... $2.07 $2.12 $2.21 $2.25 $2.30 $2.47


- ---------------

(1) The Company has various contracts to supply gas at fixed prices. In order
to lock in a margin on a portion of the volumes, the Company is a fixed
price payor on swap transactions. The average physical contract price
ranges from $2.43 in 1998 to $2.66 in 2007. The fair value of these hedges
was $3.3 million at December 31, 1997, with $(1.4) million of this value
relating to the arrangements discussed in Note 6.

when oil fell below specified reference prices during the two-year period ended
June 30, 1993, and Amoco will receive payments in the event oil prices rise
above specified reference prices for any year during the eight-year period
ending June 30, 1999. If price sharing payments are due to Amoco, the volumes
listed below would be doubled until Amoco recovers its net payments previously
made to Apache ($5.8 million through the contract year ended June 30, 1997) plus
interest.

The notional oil volumes and the reference prices specified in the Amoco
price support agreement are summarized below:



YEAR ENDED JUNE 30: MMBBLS PRICE
------------------- ------ ------

1998................................................... 1.7 $31.25
1999................................................... 1.4 33.12


Apache was not required to make any price sharing payments in 1997, and
does not expect to be liable to Amoco for future price sharing payments.

10. COMMITMENTS AND CONTINGENCIES

Litigation -- The Company is involved in litigation and is subject to
governmental and regulatory controls arising in the ordinary course of business.
It is the opinion of the Company's management that all claims and litigation
involving the Company are not likely to have a material adverse effect on its
financial position or results of operations.

Environmental -- Apache, as an owner and operator of oil and gas
properties, is subject to various federal, state, local and foreign country laws
and regulations relating to discharge of materials into, and protection of, the
environment. These laws and regulations may, among other things, impose
liability on the lessee under an oil and gas lease for the cost of pollution
clean-up resulting from operations and subject the lessee to liability for
pollution damages. Apache maintains insurance coverage, which it believes, is
customary in the industry, although it is not fully insured against all
environmental risks.

As part of the Company's due diligence review for acquisitions, Apache
conducts an extensive environmental evaluation of purchased properties.
Depending on the extent of an identified environmental problem, the Company may
exclude a property from the acquisition, require the seller to remediate the
property to Apache's satisfaction, or agree to assume liability for remediation
of the property. As of December 31, 1997, Apache had a reserve for environmental
remediation of approximately $6.4 million. The Company is not aware of any
environmental claims existing as of December 31, 1997, which have not been
provided for or would otherwise have a material impact on its financial position
or results of operations. There can be no assurance, however, that current
regulatory requirements will not change, or past non-compliance with
environmental laws will not be discovered on the Company's properties.

International Commitments -- The Company, through its subsidiaries, has
acquired or has been conditionally or unconditionally granted exploration rights
in Australia, Egypt, The People's Republic of China, Poland, the Ivory Coast and
Indonesia. In order to comply with the contracts and agreements granting these
rights, the Company, through various wholly-owned subsidiaries, is committed to
expend approximately $200 million through 2001.

Retirement and Deferred Compensation Plans -- The Company provides a 401(k)
savings plan for employees which allows participating employees to elect to
contribute up to 10 percent of their salaries, with Apache making matching
contributions up to a maximum of six percent of each employee's salary. In
addition, the Company annually contributes six percent of each participating
employee's compensation, as defined, to a money purchase retirement plan. The
401(k) plan and the money purchase retirement plan are subject to certain
annually-adjusted, government-mandated restrictions which limit the amount of
each employee's contributions.

For certain eligible employees, the Company also provides a non-qualified
retirement/savings plan which allows the deferral of up to 50 percent of each
such employee's salary, and which accepts employee contributions and the
Company's matching contributions in excess of the above-referenced restrictions
on the 401(k) savings plan and money purchase retirement plan. Additionally,
Apache Energy Limited and Apache Canada Ltd. maintain separate retirement plans,
as required under the laws of Australia and Canada, respectively.

Vesting in the Company's contributions to the 401(k) savings plan, the
money purchase retirement plan and the nonqualified retirement/savings plan
occurs at the rate of 20 percent per year. Total expenses under all plans were
$6.3 million, $6.5 million and $7.2 million for 1997, 1996 and 1995,
respectively. The unfunded liability for all plans has been accrued in the
consolidated balance sheet.

Lease Commitments -- The Company has leases for office space and equipment
with varying expiration dates through 2007. Net rental expense was $5.8 million,
$6.5 million and $5.2 million for 1997, 1996 and 1995, respectively.

As of December 31, 1997, minimum rental commitments under long-term
operating leases and long-term pipeline transportation commitments, ranging from
one to 26 years, are as follows:

ProEnergy -- ProEnergy's limited liability company agreement provides that
capital funding obligations, allocations of profit and loss and voting rights
are calculated based upon the members' respective throughputs of natural gas
sold to ProEnergy. With respect to members' votes, if there are two or more
members, the approval of any decision requires the votes of at least two members
holding the requisite voting interests. Each member's liability with respect to
future capital funding obligations is subject to certain limitations. Natural
gas throughputs are calculated, profit distributed, and/or capital called on a
quarterly basis. As of December 31, 1997, the Company held an approximate 48
percent interest in ProEnergy.

11. TRANSACTIONS WITH RELATED PARTIES AND MAJOR CUSTOMERS

Related Parties -- F.H. Merelli, a member of the Company's board of
directors since July 1997, is chairman, president and chief executive officer of
Key Production Company, Inc. (Key). In the normal course of business, Key paid
to Apache during 1997 approximately $6.5 million for Key's proportionate share
of drilling and workover costs and routine expenses relating to 360 oil and gas
wells in which Key owns interests and for which Apache is the operator. Key
received approximately $14.3 million in 1997 for its proportionate share of
revenues from such interests, of which approximately $6.1 million was paid
directly to Key by Apache or related entities.

Major Purchasers -- In 1997, purchases by ProEnergy and the Egyptian
General Petroleum Corporation accounted for 40 percent and 13 percent of the
Company's oil and gas revenues, respectively. Beginning with April 1996
production, ProEnergy was the principal purchaser of Apache's domestic natural
gas production. In 1996, purchases by ProEnergy accounted for 35 percent of the
Company's oil and gas revenues.

Natural Gas Clearinghouse (NGC) was the principal purchaser of Apache's
spot market gas production from April 1990 through September 30, 1995. Sales to
NGC accounted for 27 percent of the Company's oil and gas revenues in 1995.

Concentration of Credit Risk -- The Company's revenues are derived
principally from uncollateralized sales to customers in the oil and gas
industry; therefore, customers may be similarly affected by changes in economic
and other conditions within the industry. Apache has not experienced significant
credit losses on such sales.

Sales of natural gas by Apache to ProEnergy are similarly uncollateralized.
Apache and the other members of ProEnergy have agreed to fund the reasonably
anticipated future capital needs of ProEnergy. In addition, effective January
31, 1996, ProEnergy entered into a $150 million, three-year revolving credit
facility with a syndicate of banks to finance its operations. However, ProEnergy
remains subject to the risks inherent in the natural gas marketing industry.

Oil and Gas Reserve Information -- Proved oil and gas reserve quantities
are based on estimates prepared by the Company's engineers in accordance with
guidelines established by the Securities and Exchange Commission (SEC). The
Company's estimates of proved reserve quantities of its U.S., Canadian and
international properties are subject to review by Ryder Scott Company Petroleum
Engineers, independent petroleum engineers. In 1996, the proved reserve
quantities of certain of the Company's Egyptian properties were subject to
review by Netherland, Sewell & Associates, Inc., independent petroleum
engineers.

There are numerous uncertainties inherent in estimating quantities of
proved reserves and projecting future rates of production and timing of
development expenditures. The following reserve data represents estimates only

Future Net Cash Flows -- Future cash inflows are based on year-end oil and
gas prices except in those instances where future natural gas or oil sales are
covered by physical or derivative contract terms providing for higher or lower
amounts. Operating costs, production and ad valorem taxes and future development
costs are based on current costs with no escalation.

The following table sets forth unaudited information concerning future net
cash flows for oil and gas reserves, net of income tax expense. Income tax
expense has been computed using expected future tax rates and giving effect to
tax deductions and credits available, under current laws, and which relate to
oil and gas producing activities. This information does not purport to present
the fair market value of the Company's oil and gas assets, but does present a
standardized disclosure concerning possible future net cash flows that would
result under the assumptions used.

Impact of Pricing -- The estimates of cash flows and reserve quantities
shown above are based on year-end oil and gas prices, except in those cases
where future natural gas or oil sales are covered by contracts at specified
prices. Estimates of future liabilities and receivables applicable to oil and
gas commodity hedges are reflected in future cash flows from proved reserves
with such estimates based on prices in effect as of the date of the reserve
report. Fluctuations are largely due to supply and demand perceptions for
natural gas and volatility in oil prices.

Under SEC rules, companies that follow the full cost method of accounting
are required to perform country-by-country quarterly "ceiling test"
calculations. Under this test, capitalized costs of oil and gas properties, net
of accumulated DD&A and deferred income taxes, may not exceed the present value
of estimated future net cash flows from proved oil and gas reserves discounted
at 10 percent, net of related tax effects, plus the lower of cost or fair value
of unproved properties included in the costs being amortized. Application of
these rules during periods of relatively low oil and gas prices, even if of
short-term duration, may result in writedowns.

Many full cost companies, including Apache, are concerned about the impact
of prolonged unfavorable oil prices on their ceiling test calculations. A
deterioration of gas or oil prices from year-end levels could result in the
Company recording a non-cash charge to earnings related to its oil and gas
properties.

(1) Net income per common share has been restated in accordance with SFAS No.
128, as discussed in Note 1. The sum of the individual quarterly net income
per common share amounts may not agree with year-to-date net income per
common share as each quarterly computation is based on the weighted average
number of common shares outstanding during that period. In addition,
certain potentially dilutive securities were not included in certain of the
quarterly computations of diluted net income per common share because to do
so would have been antidilutive.
