PART I

ITEM 1. BUSINESS Atwood Oceanics, Inc. (which together with its subsidiaries is
identified as the "Company" or "Registrant", unless the context requires
otherwise), a corporation organized in 1968 under the laws of the State of
Texas, is engaged in contract drilling of exploratory and development oil and
gas wells in offshore areas and related support, management and consulting
services. The Company currently owns (i) three "third-generation"
semisubmersibles, one "second-generation" semisubmersible, one jack-up, one
"second-generation" semisubmersible tender assist rig, one submersible, and one
modular, self-contained platform rig, and (ii) a 50 percent interest in a new
generation platform rig. The Company also provides labor, supervisory and
consulting services to two operator owned platform rigs in Australia.

Despite a decline in utilization of the Company's equipment and some
dayrate reductions due to a downturn in the drilling market, fiscal 1999
represents the Company's second best financial performance in its over 30-year
history. Term contracts in place for some of the Company's rigs enabled the
Company to maintain a high level of revenues and cash flows in fiscal 1999. Even
though, the price for oil has recovered to over $20 per barrel, worldwide fleet
utilization for mobile offshore equipment still remains around 75 percent. There
are some encouraging indications that the offshore drilling market environment
could improve in 2000; however, there are no guarantees that the Company will
not incur some idle time on some of its drilling units in fiscal 2000.

Historically, most of the Company's drilling operations have been conducted
outside United States waters. Approximately 77, 69 and 88 percent of the
Company's contract revenues were derived from foreign operations in fiscal years
1999, 1998 and 1997, respectively. In addition to operating in United States
waters, the Company is currently involved in active foreign operations in the
territorial waters of Australia, Israel, Malaysia, India, Egypt and the
Philippines. The ATWOOD HUNTER, a third-generation semisubmersible, and the
submersible RICHMOND are the Company's only drilling vessels located in United
States waters. For information relating to the contract revenues, operating
income and identifiable assets attributable to specific geographic areas of
operations, see Note 13 of Notes to Consolidated Financial Statements contained
in the Company's Annual Report to Shareholders for fiscal year 1999,
incorporated by reference herein.

OFFSHORE DRILLING EQUIPMENT

The Company's diversified fleet of owned or operated drilling rigs
currently consists of four semisubmersibles, one jack-up, one semisubmersible
tender assist vessel, one submersible, and four modular, self-contained platform
rigs. Each type of drilling rig is designed for different purposes and
applications, for operations in different water depths, bottom conditions,
environments and geographical areas, and for different drilling and operating
requirements. The following descriptions of the various types of drilling rigs
owned or operated by the Company illustrate the diversified range of application
of the Company's rig fleet.

Each semisubmersible drilling unit has two hulls, the lower of which is
capable of being flooded. Drilling equipment is mounted on the main hull. After
the drilling unit is towed to location, the lower hull is flooded, lowering the
entire drilling unit to its operating draft, and the drilling unit is anchored
in place. On completion of operations, the lower hull is deballasted, raising
the entire drilling unit to its towing draft. This type of drilling unit is
designed to operate in greater water depths than a jack-up and in more severe
sea conditions than a drillship. Semisubmersible units are generally more
expensive to operate than jack-up rigs and are often limited in the amount of
supplies that can be stored on board.

The semisubmersible tender assist vessel operates like a semisubmersible
except that its drilling equipment is temporarily installed on permanently
constructed offshore support platforms. The semisubmersible vessel provides crew
accommodations, storage facilities and other support for the drilling
operations.

A jack-up drilling unit contains all of the drilling equipment on a single
hull designed to be towed to the well site. Once on location, legs are lowered
to the sea floor and the unit is raised out of the water by jacking up the legs.
On completion of the well, the unit is jacked down, and towed to the next
location. A jack-up drilling unit can operate in more severe sea and weather
conditions than a drillship and is less expensive to operate than a
semisubmersible. However, because it must rest on the sea floor, a jack-up
cannot operate in as deep water as other units.

The submersible drilling unit owned by the Company has two hulls, the lower
being a mat which is capable of being flooded. Drilling equipment and crew
accommodations are located on the main hull. After the drilling unit is towed to
its location, the lower hull is flooded, lowering the entire unit to its
operating draft at which it rests on the sea floor. On completion of operations,
the lower hull is deballasted, raising the entire unit to its towing draft. This
type of drilling unit is designed to operate in shallow water depths ranging
from 9 to 70 feet and can operate in moderately severe sea conditions. Although
drilling units of this type are less expensive to operate, like the jack-up rig,
they cannot operate in as deep water as other units.

A modular platform rig is similar to a land rig in its basic components.
Modular platform rigs are temporarily installed on permanently constructed
offshore support platforms in order to perform the drilling operations. After
the drilling phase is completed, the modular rig is broken down into convenient
packages and moved by work boats. A platform rig usually stays at a location for
several months, if not years, since several wells are typically drilled from a
support platform.

DRILLING CONTRACTS

The contracts under which the Company operates its vessels are obtained
either through individual negotiations with the customer or by submitting
proposals in competition with other contractors and vary in their terms and
conditions. The initial term of contracts for the Company's owned and/or
operated vessels has ranged from the length of time necessary to drill one well
to several months and is generally subject to early termination in the event of
a total loss of the drilling vessel, excessive equipment breakdown or failure to
meet minimum performance criteria. It is not unusual for contracts to contain
renewal provisions at the option of the customer.
The rate of compensation specified in each contract depends on the nature
of the operation to be performed, the duration of the work, the amount and type
of equipment and services provided, the geographic areas involved, market
conditions and other variables. Generally, contracts for drilling, management
and support services specify a basic rate of compensation computed on a dayrate
basis. Such agreements generally provide for a reduced dayrate payable when
operations are interrupted by equipment failure and subsequent repairs, field
moves, adverse weather conditions or other factors beyond the control of the
Company. Some contracts also provide for revision of the specified dayrates in
the event of material changes in certain items of cost. Any period during which
a vessel is not earning a full operating dayrate because of the above conditions
or because the vessel is idle and not on contract will have an adverse effect on
operating profits. An over-supply of drilling rigs in any market area can
adversely affect the Company's ability to employ its drilling vessels. Due to
decline in drilling market activities, the Company's active rig utilization
decreased from virtually 100 percent in 1998 to 77 percent in 1999. Certain
periods of idle time were incurred on the ATWOOD SOUTHERN CROSS, RICHMOND,
RIG-19 and RIG-200 during fiscal 1999. The Company anticipates incurring
additional equipment idle time in fiscal 2000.
For long moves of drilling equipment, the Company attempts to obtain
either a lump sum or a dayrate as mobilization compensation for expenses
incurred during the period in transit. A surplus of certain types of units,
either worldwide or in particular operating areas, can result in the Company's
acceptance of a contract which provides only partial or no recovery of
relocation costs. In recent times, the Company has received full recovery of
relocation costs; however, there can be no assurance that this trend will
continue.

Operation of the Company's drilling equipment is subject to the offshore
drilling requirements of petroleum exploration companies and agencies of foreign
governments. These requirements are, in turn, subject to fluctuations in
government policies, world demand and prices for petroleum products, proved
reserves in relation to such demand and the extent to which such demand can be
met from onshore sources.

The Company also contracts to provide various types of services to third
party owners of drilling rigs. These contracts are normally for a stated term or
until termination of operations or stages of operation at a particular facility
or location. The services may include, as in the case of contracts entered into
by the Company in connection with operations offshore Australia, the supply of
personnel and rig design, fabrication, installation and operation. The contracts
normally provide for reimbursement to the Company for all out-of-pocket
expenses, plus a service or management fee for all of the services performed. In
most instances, the amount charged for the services may be adjusted if there are
changes in conditions, scope or costs of operations. The Company generally
obtains insurance or a contractual indemnity from the owner for liabilities
which could be incurred in operations.

OPERATIONAL RISKS AND INSURANCE

The Company's operations are subject to the usual hazards associated with
the drilling of oil and gas wells, such as blowouts, explosions and fires. In
addition, the Company's vessels are subject to those perils peculiar to marine
operations, such as capsizing, grounding, collision and damage from severe
weather conditions. Any of these risks could result in damage or destruction of
drilling rigs and oil and gas wells, personal injury and property damage,
suspension of operations or environmental damage through oil spillage or
extensive, uncontrolled fires. Although the Company believes that it is
adequately insured against normal and foreseeable risks in its operations in
accordance with industry standards, such insurance may not be adequate to
protect the Company against liability from all consequences of well disasters,
marine perils, extensive fire damage or damage to the environment. To date, the
Company has not experienced difficulty in obtaining insurance coverage, although
no assurance can be given as to the future availability of such insurance or
cost thereof. The occurrence of a significant event against which the Company is
not fully insured could have a material adverse effect on the Company's
financial position.



ENVIRONMENTAL PROTECTION

Under the Federal Water Pollution Control Act, as amended by the Oil
Pollution Act of 1990, operators of vessels in navigable United States waters
and certain offshore areas are liable to the United States government for the
costs of removing oil and certain other pollutants for which they may be held
responsible, subject to certain limitations, and must establish financial
responsibility to cover such liability. The Company has taken all steps
necessary to comply with this law, and has received a Certificate of Financial
Responsibility (Water Pollution) from the U.S. Coast Guard. The Company's
operations in United States waters are also subject to various other
environmental regulations regarding pollution and control thereof, and the
Company has taken steps to ensure compliance therewith.

CUSTOMERS

During fiscal year 1999 the Company performed operations for 13 customers.
Because of the relatively limited number of customers for which the Company can
operate at any given time, sales to each of 3 different customers amounted to
10% or more of the Company's fiscal 1999 revenues. Shell Philippines Exploration
B.V/Sabah Shell Petroleum Company Limited, British-Borneo Petroleum Inc., and
Esso Australia Limited/Esso Production Malaysia, Inc., accounted for 24%, 21%
and 16%, respectively, of fiscal year 1999 revenues. The Company's business
operations are subject to the risks associated with a business having a limited
number of customers for its products or services, and a decrease in the drilling
programs of these customers in the areas where they employ the Company may
adversely affect the Company's revenues.


COMPETITION

The Company competes with numerous other drilling contractors, most of
which are substantially larger than the Company and possess appreciably greater
financial and other resources. Although recent business combinations among
drilling companies have resulted in a decrease in the total number of
competitors, the drilling industry remains competitive, with no single drilling
contractor being dominant. Thus, there continues to be competition in securing
available drilling contracts.

Price competition is generally the most important factor in the drilling
industry, but the technical capability of specialized drilling equipment and
personnel at the time and place required by customers is also important. Other
competitive factors include work force experience, rig suitability, efficiency,
condition of equipment, reputation and customer relations. The Company believes
that it competes favorably with respect to these factors. If demand for drilling
rigs increases in the future, rig availability may also become a competitive
factor. Competition usually occurs on a regional basis and, although drilling
rigs are mobile and can be moved from one region to another in response to
increased demand, an oversupply of rigs in any region may result. Demand for
drilling equipment is also dependent on the exploration and development programs
of oil and gas companies, which are in turn influenced by the financial
condition of such companies, by general economic conditions, by prices of oil
and gas, and from time to time by political considerations and policies.

FOREIGN OPERATIONS

The operations of the Company are conducted primarily in foreign waters
and are subject to certain political, economic and other uncertainties not
encountered by purely domestic drilling contractors, including risks of
expropriation, nationalization, foreign exchange restrictions, foreign taxation,
changing conditions and foreign and domestic monetary policies. Generally, the
Company purchases insurance to protect against some or all loss due to events of
political risk such as nationalization, expropriation, war, confiscation and
deprivation. Occasionally, customers will indemnify the Company against such
losses. Moreover, offshore drilling activity is affected by government
regulations and policies limiting the withdrawal of offshore oil and gas,
regulations affecting production, regulations restricting the importation of
foreign petroleum, environmental regulations and regulations which may limit
operations in offshore areas by foreign companies and/or personnel. See Note 13
to Consolidated Financial Statements contained in the Company's Annual Report to
Shareholders for fiscal year 1999, incorporated herein by reference, for a
summary of contract revenues, operating income and identifiable assets by
geographic region.

Because of the Company's foreign operations, its overall effective tax
rate may in the future be higher than the maximum United States corporate
statutory rate due to the possibility of higher foreign tax rates in certain
jurisdictions or less than full creditability of foreign taxes paid.





EMPLOYEES

The Company currently employs approximately 700 persons in its domestic
and worldwide operations. In connection with its foreign drilling operations,
the Company has often been required by the host country to hire substantial
portions of its work force in that country and, in some cases, these employees
may be represented by foreign unions. To date, the Company has experienced
little difficulty in complying with such requirements, and the Company's
drilling operations have not been significantly interrupted by
strikes or work stoppages.

ITEM 2. PROPERTIES

Information regarding the location and general character of the Company's
principal assets may be found in the table with the caption heading "Offshore
Drilling Operations" in the Company's Annual Report to Shareholders for fiscal
year 1999, which is incorporated by reference herein.

Since 1997, the Company has successfully upgraded four drilling units; the
ATWOOD HUNTER, the ATWOOD SOUTHERN CROSS, the ATWOOD FALCON and the VICKSBURG at
approximate costs of $40 million, $35 million, $50 million and $35 million,
respectively. During 1999 the Company commenced an approximate $23 million
upgrade of the SEAHAWK for a four-year contract extension, of which
approximately $20 million will be reimbursed by the customer. For more
information concerning these costs, see Note 4 in Consolidated Financial
Statements contained in the Company's Annual Report to Shareholders for fiscal
year 1999, incorporated by reference herein.


ITEM 3. LEGAL PROCEEDINGS

The Company is not currently involved in any material legal proceedings.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SHAREHOLDERS

During the fourth quarter of fiscal 1999, no matters were submitted to
a vote of shareholders through the solicitation of proxies or otherwise.


PART II

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED SHAREHOLDER
MATTERS

As of September 30, 1999, there were over 750 beneficial owners of the
Company's common stock.

The Company did not pay cash dividends in fiscal years 1998 or 1999 and
the Company does not anticipate paying cash dividends in the foreseeable future
because of the capital intensive nature of its business. To enable the company
to maintain its high competitive profile in the industry, cash reserves will be
utilized, at the appropriate time, to upgrade existing equipment or to acquire
additional equipment. The Company's revolving credit facility prohibits the
Company from paying dividends on common stock.
