Part I

Item 1. Business

General
Southwest Royalties Institutional Income Fund XI-A, L.P. (the "Partnership"
or "Registrant") was organized as a Delaware limited partnership on May 5,
1992. The offering of limited partnership interests began August 20, 1992,
as part of a shelf offering registered under the name Southwest Royalties
Institutional 1992-93 Income Program, reached minimum capital requirements
on December 10, 1992 and concluded April 30, 1993. The Partnership has no
subsidiaries.

The Partnership has acquired interests in producing oil and gas properties
and produced and marketed the crude oil and natural gas produced from such
properties. In most cases, the Partnership purchased royalty or overriding
royalty interests and working interests in oil and gas properties that were
converted into net profits interests or other non-operating interests. The
Partnership purchased either all or part of the rights and obligations
under various oil and gas leases.

The principal executive offices of the Partnership are located at 407 N.
Big Spring, Suite 300, Midland, Texas, 79701. The Managing General Partner
of the Partnership, Southwest Royalties, Inc. (the "Managing General
Partner") and its staff of 130 individuals, together with certain
independent consultants used on an "as needed" basis, perform various
services on behalf of the Partnership, including the selection of oil and
gas properties and the marketing of production from such properties. H. H.
Wommack, III, a stockholder, director, President and Treasurer of the
Managing General Partner, is also a general partner. The Partnership has
no employees.

Principal Products, Marketing and Distribution
The Partnership has acquired and holds royalty interests and net profit
interests in oil and gas properties located in Alabama, Kansas, Louisiana,
Mississippi, New Mexico, Oklahoma and Texas. All activities of the
Partnership are confined to the continental United States. All oil and gas
produced from these properties is sold to unrelated third parties in the
oil and gas business.

The revenues generated from the Partnership's oil and gas activities are
dependent upon the current market for oil and gas. The prices received by
the Partnership for its oil and gas production depend upon numerous factors
beyond the Partnership's control, including competition, economic,
political and regulatory developments and competitive energy sources, and
make it particularly difficult to estimate future prices of oil and natural
gas.



1997 was another volatile year in the oil market. Prices ranged from a
high of approximately $26 in the first quarter to a low near $18 per
barrel. Two contributing factors that influence the oil industry are the
strength of the economy and activity in the Middle East. Both influenced
the supply and demand of oil, and both played roles in price swings this
year. Economic expansion throughout the world enabled consumption to
surpass 70 million barrels of oil per day. However, early in the year,
producing countries failed to make up the difference in supply, placing
upward pressure on prices. U.S. production fell slightly in 1997 to
average roughly 6.4 million barrels of oil per day. Over the Thanksgiving
weekend, OPEC agreed to increase their crude oil production ceiling by
approximately 10%, but experts have said that many OPEC countries were
already producing beyond their quotas, therefore, capacity is not expected
to expand severely. Then on December 4th, the UN Security Council approved
a renewal of the Iraqi oil-for-food program. The OPEC agreement and the
UN's decision on the oil-for-food program will certainly increase the world
supply of oil and most likely depress prices in the near term. However,
world demand is expected to continue with strong growth in 1998.

The December 31, 1997 NYMEX oil price of $17.64 dropped to $14.32 as of
March 18, 1998. The price decline in the first quarter of 1998 could cause
a material write down in oil and gas properties and a possible reduction in
future distributions to investors.

Overall the 1997 average price of natural gas increased nationwide from the
1996 rates. In some areas the increase was as high as 15%. The 1996 and
1997 average prices are by far the highest realized by the industry since
1985. The 1998 average price is expected to remain above the $2.00 per
MMBTU level, however some early signs indicate that the prices will be
softer in 1998 than they were in 1997. Forecasts for a mild winter and the
lack of gas storage withdrawals are fueling speculation that the U.S. has
an excess supply of gas thus driving the prices down to the early 1996
levels.

Following is a table of the ratios of revenues received from oil and gas
production for the last three years:

Oil Gas

1997 45% 55%
1996 48% 52%
1995 47% 53%

As the table indicates, the Partnership's revenue is almost evenly divided
between its oil and gas production, the Partnership revenues will be highly
dependent upon the future prices and demands for oil and gas.

Seasonality of Business
Although the demand for natural gas is highly seasonal, with higher demand
in the colder winter months and in very hot summer months, the Partnership
has been able to sell all of its natural gas, either through contracts in
place or on the spot market at the then prevailing spot market price. As a
result, the volumes sold by the Partnership have not fluctuated materially
with the change of season.



Customer Dependence
No material portion of the Partnership's business is dependent on a single
purchaser, or a very few purchasers, where the loss of one would have a
material adverse impact on the Partnership. Two purchasers accounted for
37% of the Partnership's total oil and gas production during 1997:
American Processing 24%, and Navajo Refining Company, Inc. 13%. Three
purchasers accounted for 47% of the Partnership's total oil and gas
production during 1996: American Processing 20%, Navajo Refining Company,
Inc. 14% and Torch Operating Company 13%. Three purchasers accounted for
50% of the Partnership's total oil and gas production during 1995:
American Processing, Navajo Refining Company and Nustar Joint Venture
purchased 20%, 15% and 15%, respectively. All purchasers of the
Partnership's oil and gas production are unrelated third parties. In the
event any of these purchasers were to discontinue purchasing the
Partnership's production, the Managing General Partner believes that a
substitute purchaser or purchasers could be located without undue delay.
No other purchaser accounted for an amount equal to or greater than 10% of
the Partnership's sales of oil and gas production.

Competition
Because the Partnership has utilized all of its funds available for the
acquisition of net profits or royalty interests in producing oil and gas
properties, it is not subject to competition from other oil and gas
property purchasers. See Item 2, Properties

Factors that may adversely affect the Partnership include delays in
completing arrangements for the sale of production, availability of a
market for production, rising operating costs of producing oil and gas and
complying with applicable water and air pollution control statutes,
increasing costs and difficulties of transportation, and marketing of
competitive fuels. Moreover, domestic oil and gas must compete with
imported oil and gas and with coal, atomic energy, hydroelectric power and
other forms of energy.

Regulation

Oil and Gas Production - The production and sale of oil and gas is subject
to federal and state governmental regulation in several respects, such as
existing price controls on natural gas and possible price controls on crude
oil, regulation of oil and gas production by state and local governmental
agencies, pollution and environmental controls and various other direct and
indirect regulation. Many jurisdictions have periodically imposed
limitations on oil and gas production by restricting the rate of flow for
oil and gas wells below their actual capacity to produce and by imposing
acreage limitations for the drilling of wells. The federal government has
the power to permit increases in the amount of oil imported from other
countries and to impose pollution control measures.


Various aspects of the Partnership's oil and gas activities will be
regulated by administrative agencies under statutory provisions of the
states where such activities are conducted and by certain agencies of the
federal government for operations on Federal leases. Moreover, certain
prices at which the Partnership may sell its natural gas production are
controlled by the Natural Gas Policy Act of 1978, the Natural Gas Wellhead
Decontrol Act of 1989 and the regulations promulgated by the Federal Energy
Regulatory Commission.

Environmental - The Partnership's oil and gas activities will be subject to
extensive federal, state and local laws and regulations governing the
generation, storage, handling, emission, transportation and discharge of
materials into the environment. Governmental authorities have the power to
enforce compliance with their regulations, and violations carry substantial
penalties. This regulatory burden on the oil and gas industry increases
its cost of doing business and consequently affects its profitability. The
Managing General Partner is unable to predict what, if any, effect
compliance will have on the Partnership.

Industry Regulations and Guidelines - Industry regulations and guidelines
apply to the registration, qualification and operation of oil and gas
programs in the form of limited partnerships. The Partnership is subject
to these guidelines which regulate and restrict transactions between the
Managing General Partner and the Partnership. The Partnership complies
with these guidelines and the Managing General Partner does not anticipate
that continued compliance will have a material adverse effect on
Partnership operations.

Partnership Employees

The Partnership has no employees; however, the Managing General Partner has
a staff of geologists, engineers, accountants, landmen and clerical staff
who engage in Partnership activities and operations and perform additional
services for the Partnership as needed. In addition to the Managing
General Partner's staff, the Partnership engages independent consultants
such as petroleum engineers and geologists as needed. As of December 31,
1997, there were 130 individuals directly employed by the Managing General
Partner in various capacities.

Item 2. Properties

In determining whether an interest in a particular producing property was
to be acquired, the Managing General Partner considered such criteria as
estimated oil and gas reserves, estimated cash flow from the sale of
production, present and future prices of oil and gas, the extent of
undeveloped and unproved reserves, the potential for secondary, tertiary
and other enhanced recovery projects and the availability of markets.

As of December 31, 1997, the Partnership possessed an interest in oil and
gas properties located in Escambia, Fayette and Lamar Counties of Alabama;
Labette and Neosho Counties of Kansas; Cameron, Jefferson, La Fourche,
Pointe Coupe and Terrebonne Parishes of Louisiana; Chickasaw, Lowndes and
Monroe Counties of Mississippi; Eddy and Lea Counties of New Mexico;
Custer, Roger Mills and Washita Counties of Oklahoma; and Borden, Crockett,
Dewitt, Dickens, Ector, Fayette, Gaines, Grayson, Hemphill, Howard, Live
Oak, Nueces, Reagan, Reeves, Sutton, Upton, Ward, Winkler, and Yoakum
Counties of Texas. These properties consist of various interests in 205
wells and units.

Due to the Partnership's objective of maintaining current operations
without engaging in the drilling of any developmental or exploratory wells,
or additional acquisitions of producing properties, there have not been any
significant changes in properties during 1997 and 1996.

During 1995, the Partnership acquired the Kaiser State 44 acquisition,
located in Lea County, New Mexico, for approximately $90,000. The
acquisition was effective as of June 1, 1995 and was purchased from an
unrelated third party, Elkhorn Oil and Gas, LLC.


In compliance with the Partnership Agreement, if the Partnership should
purchase a producing property from the Managing General Partner, such
purchase price would be prior cost, adjusted for any intervening
operations. If such adjusted cost was greater than fair market value, or
if specific cost was unable to be determined, such purchase price would be
fair market value as determined by an independent reservoir engineer.

Upon a determination by Management that they were either not profitable to
own or Management received an offer that exceeded the leases reserves, the
following leases were sold.

During 1997, four leases were sold for approximately $44,700. The Wegner
and Medley were sold effective October 1997. The W. Jordan was sold
effective June 1997.

During 1996, four leases were sold for approximately $6,200. The Epps and
Holmon were sold effective March 1996, Conner was sold effective April 1996
and Haun was sold effective July 1996.

During 1995, six leases were sold for approximately $136,000. The State of
Texas EY was sold effective January 1995, the Leverton, Sealy Unit and
Foster E were sold effective April 1995, the Caviness Paine 4 was sold
effective November 1995 and the Gilliland was sold effective July 1995.

*The reserve estimates were prepared as of January 1, 1998, by Donald R.
Creamer, P.E., an independent registered petroleum engineer. The reserve
estimates were made in accordance with guidelines established by the
Securities and Exchange Commission pursuant to Rule 4-10(a) of Regulation S-
X. Such guidelines require oil and gas reserve reports be prepared under
existing economic and operating conditions with no provisions for price and
cost escalation except by contractual arrangements.

The New York Mercantile Exchange price at December 31, 1997 of $17.64 was
used as the beginning basis for the oil price. Oil price adjustments from
$17.64 per barrel were made in the individual evaluations to reflect oil
quality, gathering and transportation costs. The results are an average
price received at the lease of $16.09 per barrel in the preparation of the
reserve report as of January 1, 1998.

In the determination of the gas price, the New York Mercantile Exchange
price at December 31, 1997 of $2.26 was used as the beginning basis. Gas
price adjustments from $2.26 per Mcf were made in the individual
evaluations to reflect BTU content, gathering and transportation costs and
gas processing and shrinkage. The results are an average price received at
the lease of $2.12 per Mcf in the preparation of the reserve report as of
January 1, 1998.

As also discussed in Item 7, Management's Discussion and Analysis of
Financial Condition and Results of Operations, oil prices were subject to
frequent changes in 1997.


The evaluation of oil and gas properties is not an exact science and
inevitably involves a significant degree of uncertainty, particularly with
respect to the quantity of oil or gas that any given property is capable of
producing. Estimates of oil and gas reserves are based on available
geological and engineering data, the extent and quality of which may vary
in each case and, in certain instances, may prove to be inaccurate.
Consequently, properties may be depleted more rapidly than the geological
and engineering data have indicated.

Unanticipated depletion, if it occurs, will result in lower reserves than
previously estimated; thus an ultimately lower return for the Partnership.
Basic changes in past reserve estimates occur annually. As new data is
gathered during the subsequent year, the engineer must revise his earlier
estimates. A year of new information, which is pertinent to the estimation
of future recoverable volumes, is available during the subsequent year
evaluation. In applying industry standards and procedures, the new data
may cause the previous estimates to be revised. This revision may increase
or decrease the earlier estimated volumes. Pertinent information gathered
during the year may include actual production and decline rates, production
from offset wells drilled to the same geologic formation, increased or
decreased water production, workovers, and changes in lifting costs, among
others. Accordingly, reserve estimates are often different from the
quantities of oil and gas that are ultimately recovered.

The Partnership has reserves which are classified as proved developed
producing, proved developed non-producing and proved undeveloped. All of
the proved reserves are included in the engineering reports which evaluate
the Partnership's present reserves.

Because the Partnership does not engage in drilling activities, the
development of proved undeveloped reserves is conducted pursuant to farm-
out arrangements with the Managing General Partner or unrelated third
parties. Generally, the Partnership retains a carried interest such as an
overriding royalty interest under the terms of a farm-out, or receives
cash.

The Partnership or the owners of properties in which the Partnership owns
an interest can engage in workover projects or supplementary recovery
projects, for example, to extract behind the pipe reserves which qualify as
proved developed non-producing reserves. See Part II, Item 7, Management's
Discussion and Analysis of Financial Condition and Results of Operations.

Item 3. Legal Proceedings

There are no material pending legal proceedings to which the Partnership is
a party.

Item 4. Submission of Matters to a Vote of Security Holders

No matter was submitted to a vote of security holders during the fourth
quarter of 1997 through the solicitation of proxies or otherwise.


Part II


Item 5. Market for the Registrant's Common Equity and Related Stockholder
Matters

Market Information

Limited partnership interests, or units, in the Partnership were initially
offered and sold for a price of $500. Limited partner units are not traded
on any exchange and there is no public or organized trading market for
them. The Managing General Partner has become aware of certain limited and
sporadic transfers of units between limited partners and third parties, but
has no verifiable information regarding the prices at which such units have
been transferred. Further, a transferee may not become a substitute
limited partner without the consent of the Managing General Partner.

The Managing General Partner has the right, but not the obligation, to
purchase limited partnership units should an investor desire to sell. The
value of the unit is determined by adding the sum of (1) current assets
less liabilities and (2) the present value of the future net revenues
attributable to proved reserves and by discounting the future net revenues
at a rate not in excess of the prime rate charged by NationsBank, N.A. of
Midland, Texas plus one percent (1%), which value shall be further reduced
by a risk factor discount of no more than one-third (1/3) to be determined
by the Managing General Partner in its sole and absolute discretion. In
1997, 126 limited partner units were tendered to and purchased by the
Managing General Partner at an average base price of $192.93 per unit. In
1996, 200 limited partner units were tendered to and purchased by the
Managing General Partner at an average base price of $232.87 per unit. No
units were acquired in 1995.

Number of Limited Partner Interest Holders

As of December 31, 1997, there were 221 holders of limited partner units in
the Partnership.

Distributions

Pursuant to Article III, Section 3.05 of the Partnership's Certificate and
Agreement of Limited Partnership "Net Cash Flow" shall be distributed to
the partners on a monthly basis. "Net Cash Flow" is defined as "the cash
generated by the Partnership's investments in producing oil and gas
properties, less (i) General and Administrative Costs, (ii) Direct Costs,
(iii) Operating Costs, and (iv) any reserves necessary to meet current and
anticipated needs of the Partnership, as determined in the sole discretion
of the Managing General Partner."


During 1997, twelve monthly distributions were made totaling $363,956, with
$331,256 distributed to the limited partners and $32,700 to the general
partners. For the year ended December 31, 1997, distributions of $61.14
per limited partner unit were made, based upon 5,418 limited partner units
outstanding. During 1996, twelve monthly distributions were made totaling
$454,785, with $414,535 distributed to the limited partners and $40,250 to
the general partners. For the year ended December 31, 1996, distributions
of $76.51 per limited partner unit were made, based upon 5,418 limited
partner units outstanding. During 1995, twelve monthly distributions were
made totaling $431,831, with $388,931 distributed to the limited partners
and $42,900 to the general partners. For the year ended December 31, 1995,
distributions of $71.78 per limited partner unit were made, based on 5,418
limited partner units outstanding.

Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations

General

Southwest Royalties Institutional Income Fund XI-A, L.P. was organized as a
Delaware limited partnership on May 5, 1992. The offering of limited
partnership interests began August 20, 1992, as part of a shelf offering
registered under the name Southwest Royalties Institutional 1992-93 Income
Program. Minimum capital requirements for the Partnership were met on
December 10, 1992, and the Offering Period terminated April 30, 1993 with
213 limited partners purchasing 5,418 units for $2,709,000.

The Partnership was formed to acquire non-operating interests in producing
oil and gas properties, to produce and market crude oil and natural gas
produced from such properties and to distribute any net proceeds from
operations to the general and limited partners. Net revenues from
producing oil and gas properties will not be reinvested in other revenue
producing assets except to the extent that producing facilities and wells
are reworked or where methods are employed to improve or enable more
efficient recovery of oil and gas reserves. The economic life of the
Partnership will thus depend on the period over which the Partnership's oil
and gas reserves are economically recoverable.

Increases or decreases in Partnership revenues and, therefore,
distributions to partners will depend primarily on changes in the prices
received for production, changes in volumes of production sold, lease
operating expenses, enhanced recovery projects, offset drilling activities
pursuant to farm-out arrangements and on the depletion wells. Since wells
deplete over time, production can generally be expected to decline from
year to year.

Well operating costs and general and administrative costs usually decrease
with production declines; however, these costs may not decrease
proportionately. Net income available for distribution to the limited
partners has fluctuated over the past few years and is expected to
fluctuate in later years based on these factors.

Based on current conditions, management anticipates performing workovers
during 1998 to enhance production. The Partnership could possibly
experience the following changes; a little less than normal decline in 1998
and thereafter, experience a steady decline.


Results of Operations

A. General Comparison of the Years Ended December 31, 1997 and 1996

The following table provides certain information regarding performance
factors for the years ended December 31, 1997 and 1996:

Year Ended Percentage
December 31, Increase
1997 1996 (Decrease)
---- ---- --------

Average price per barrel of oil $ 18.80 20.95 (10%)
Average price per mcf of gas $ 2.25 2.22 1%
Oil production in barrels 16,100 19,600 (18%)
Gas production in mcf 161,900 202,500 (20%)
Income from net profits interests $ 279,147 451,477 (38%)
Partnership distributions $ 363,956 454,785 (20%)
Limited partner distributions $ 331,256 414,535 (20%)
Per unit distribution to limited partners $ 61.14 76.51 (20%)
Number of limited partner units 5,418 5,418

Revenues

The Partnership's income from net profits interests decreased to $279,147
from $451,477 for the years ended December 31, 1997 and 1996, respectively,
a decrease of 38%. The principal factors affecting the comparison of the
years ended December 31, 1997 and 1996 are as follows:

1. The average price for a barrel of oil received by the Partnership
decreased during the year ended December 31, 1997 as compared to the
year ended December 31, 1996 by 10%, or $2.15 per barrel, resulting in
a decrease of approximately $42,100 in income from net profits
interests. Oil sales represented 45% of total oil and gas sales during
the year ended December 31, 1997 as compared to 48% during the year
ended December 31, 1996.

The average price for an mcf of gas received by the Partnership
increased during the same period by 1%, or $.03 per mcf, resulting in
an increase of approximately $6,100 in income from net profits
interests.

The net total decrease in income from net profits interests due to the
change in prices received from oil and gas production is approximately
$36,000 . The market price for oil and gas has been extremely volatile
over the past decade and management expects a certain amount of
volatility to continue in the foreseeable future.


2. Oil production decreased approximately 3,500 barrels or 18% during the
year ended December 31, 1997 as compared to the year ended December 31,
1996, resulting in a decrease of approximately $65,800 in income from
net profits interests.

Gas production decreased approximately 40,600 mcf or 20% during the
same period, resulting in a decrease of approximately $91,400 in income
from net profits interests.

The total decrease in income from net profits interests due to the
change in production is approximately $157,200. The decrease in
production is due primarily to a well being shut-in for 30 days and
normal decline.

3. Lease operating costs and production taxes were 5% lower, or
approximately $21,100 less during the year ended December 31, 1997 as
compared to the year ended December 31, 1996.

4. As of December 31, 1997, miscellaneous income was approximately
$94,424. The income is a result of a purchase agreement, on the Tar
Baby lease, that guarantees the Partnership a net income of
approximately $3,400 monthly from October 1994 to January 1998.

Costs and Expenses

Total costs and expenses increased to $510,897 from $245,788 for the years
ended December 31, 1997 and 1996, respectively, an increase of 108%. The
increase is the result of higher depletion expense and a provision for
impairment of oil and gas properties.

1. General and administrative costs consists of independent accounting and
engineering fees, computer services, postage, and Managing General
Partner personnel costs. General and administrative costs decreased
less than one percent or approximately $100 during the year ended
December 31, 1997 as compared to the year ended December 31, 1996.

2. Depletion expense increased to $249,000 for the year ended December
31, 1997 from $186,000 for the same period in 1996. This represents an
increase of 34%. Depletion is calculated using the units of revenue method
of amortization based on a percentage of current period gross revenues to
total future gross oil and gas revenues, as estimated by the Partnership's
independent petroleum consultants.

A contributing factor to the increase in depletion expense between the
comparative periods was the decrease in the price of oil and gas used
to determine the Partnership's reserves for January 1, 1998 as compared
to 1997. Another contributing factor was due to the impact of
revisions of previous estimates on reserves. Revisions of previous
estimates can be attributed to the changes in production performance,
oil and gas price and production costs. The impact of the revision
would have increased depletion expense approximately $88,000 as of
December 31, 1996.

3. The Partnership reduced the net capitalized costs of oil and gas
properties by $202,822. This provision for impairment had the effect
of reducing net income, but did not affect cash flow or partner
distributions. See Summary of Significant Accounting Policies - Oil
and Gas Properties.



Results of Operations

B. General Comparison of the Years Ended December 31, 1996 and 1995

The following table provides certain information regarding performance
factors for the years ended December 31, 1996 and 1995:

Year Ended Percentage
December 31, Increase
1996 1995 (Decrease)
---- ---- ---------

Average price per barrel of oil $ 20.95 16.90 24%
Average price per mcf of gas $ 2.22 1.56 42%
Oil production in barrels 19,600 21,000 (7%)
Gas production in mcf 202,500 255,000 (21%)
Income from net profits interests $ 451,477 335,870 34%
Partnership distributions $ 454,785 431,831 5%
Limited partner distributions $ 414,535 388,931 7%
Per unit distribution to limited partners $ 76.51 71.78 7%
Number of limited partner units 5,418 5,418

Revenues

The Partnership's income from net profits interests increased to $451,477
from $335,870 for the years ended December 31, 1996 and 1995, respectively,
an increase of 34%. The principal factors affecting the comparison of the
years ended December 31, 1996 and 1995 are as follows:

1. The average price for a barrel of oil received by the Partnership
increased during the year ended December 31, 1996 as compared to the
year ended December 31, 1995 by 24%, or $4.05 per barrel, resulting in
an increase of approximately $85,100 in income from net profits
interests. Oil sales represented 48% of total oil and gas sales during
the year ended December 31, 1996 as compared to 47% during the year
ended December 31, 1995.

The average price for an mcf of gas received by the Partnership
increased during the same period by 42%, or $.66 per mcf, resulting in
an increase of approximately $168,300 in income from net profits
interests.

The total increase in income from net profits interests due to the
change in prices received from oil and gas production is approximately
$253,400. The market price for oil and gas has been extremely volatile
over the past decade and management expects a certain amount of
volatility to continue in the foreseeable future.


2. Oil production decreased approximately 1,400 barrels or 7% during the
year ended December 31, 1996 as compared to the year ended December 31,
1995, resulting in a decrease of approximately $29,300 in income from
net profits interests.

Gas production decreased approximately 52,500 mcf or 21 % during the
same period, resulting in a decrease of approximately $116,600 in
income from net profits interests.

The total decrease in income from net profits interests due to the
change in production is approximately $145,900. The decrease is
primarily a result of property sales and surface problems.

3. As of December 31, 1996, miscellaneous income was approximately
$77,000. The income is a result of a purchase agreement, on the Tar
Baby lease, that guarantees the Partnership a net income of
approximately $3,400 monthly from October 1994 to January 1998.

4. Lease operating costs and production taxes were 1% lower, or
approximately $4,600 less during the year ended December 31, 1996 as
compared to the year ended December 31, 1995.

Costs and Expenses

Total costs and expenses decreased to $245,788 from $300,514 for the years
ended December 31, 1996 and 1995, respectively, a decrease of 18%. The
decrease is the result of lower general and administrative expense and
depletion expense.

1. General and administrative costs consists of independent accounting and
engineering fees, computer services, postage, and Managing General
Partner personnel costs. General and administrative costs increased 1%
or approximately $200 during the year ended December 31, 1996 as
compared to the year ended December 31, 1995.

3. Depletion expense decreased to $186,000 for the year ended December
31, 1996 from $240,000 for the same period in 1995. This represents a
decrease of 23%. Depletion is calculated using the units of revenue method
of amortization based on a percentage of current period gross revenues to
total future gross oil and gas revenues, as estimated by the Partnership's
independent petroleum consultants.

A contributing factor to the decline in depletion expense between the
comparative periods were the increase in the price of oil and gas used
to determine the Partnership's reserves for January 1, 1997 as compared
to 1996. Another contributing factor was due to the impact of
revisions of previous estimates on reserves. Revisions of previous
estimates can be attributed to the changes in production performance,
oil and gas price and production costs. The impact of the revision
would have decreased depletion expense approximately $23,000 as of
December 31, 1995.



C. Revenue and Distribution Comparison

Partnership net income or (loss) for the years ended December 31, 1997,
1996 and 1995 was $(133,264), $285,720 and $42,213, respectively.
Excluding the effects of depreciation, depletion, amortization and
provision for impairment, net income for the years ended December 31, 1997,
1996 and 1995 would have been $327,711, $481,493 and $292,533,
respectively. Correspondingly, Partnership distributions for the years
ended December 31, 1997, 1996 and 1995 were $363,956, 454,785 and $431,831,
respectively. These differences are indicative of the changes in oil and
gas prices, production and properties during 1997, 1996 and 1995.

The sources for the 1997 distributions of $363,956 were oil and gas
operations of approximately $366,400 and the change in oil and gas
properties of approximately $43,200, result in excess cash for
contingencies or subsequent distributions. The sources for the 1996
distributions of $454,785 were oil and gas operations of approximately
$379,900, refund of excess capital of approximately $48,100 and property
sales of approximately $6,200, with the balance from available cash on hand
at the beginning of the period. The sources for the 1995 distributions of
$431,831 were oil and gas operations of $307,345 and property sales of
$136,013, reduced by additions to oil and gas properties of $92,314, with
the balance from available cash on hand at the beginning of the period.

Total distributions during the year ended December 31, 1997 were $363,956
of which $331,256 was distributed to the limited partners and $32,700 to
the general partners. The per unit distribution to limited partners during
the same period was $61.14. Total distributions during the year ended
December 31, 1996 were $454,785 of which $414,535 was distributed to the
limited partners and $40,250 to the general partners. The per unit
distribution to limited partners during the same period was $76.51. Total
distributions during the year ended December 31, 1995 were $431,831 of
which $388,931 was distributed to the limited partners and $42,900 to the
general partners. The per unit distribution to limited partners during the
same period was $71.78.

Since inception of the Partnership, cumulative monthly cash distributions
of $1,355,448 have been made to the partners. As of December 31, 1997,
$1,239,598 or $228.79 per limited partner unit, has been distributed to the
limited partners, representing a 46% return of the capital contributed.



Liquidity and Capital Resources

The primary source of cash is from operations, the receipt of income from
net profits interests in oil and gas properties. The Partnership knows of
no material change, nor does it anticipate any such change.

The December 31, 1997 NYMEX oil price of $17.64 dropped to $14.32 as of
March 18, 1998. The price decline in the first quarter of 1998 could cause
a material write down in oil and gas properties and a possible reduction in
future distributions to investors.

Cash flows provided by operating activities were approximately $366,400 in
1997 compared to $379,900 in 1996 and approximately $307,300 in 1995. The
primary source of the 1997 cash flow from operating activities was
profitable operations.

Cash flows provided by or investing activities were approximately $43,200
in 1997 compared to $7,900 in 1996 and approximately $43,700 in 1995. The
principal source of the 1997 cash flow from investing activities was from
the sale of oil and gas properties.

Cash flows provided by financing activities were approximately $364,000 in
1997 compared to $454,800 in 1996 and approximately $432,000 in 1995. The
only 1997 use in financing activities was the distributions to partners.

As of December 31, 1997, the Partnership had approximately $191,200 in
working capital. The Managing General Partner knows of no other
commitments and believes the revenues generated from operations will be
adequate to meet the operating needs of the Partnership.

Information Systems for the Year 2000

The Managing General Partner provides all data processing needs of the
Partnership. The Managing General Partner has reviewed and evaluated its
information systems to determine if its systems accurately process data
referencing the year 2000. Primarily all necessary programming
modifications to correct year 2000 referencing in the Managing General
Partners internal accounting and operating systems have been made to-date.
However the Managing General Partner has not completed its evaluation of
its vendors and suppliers systems to determine the effect, if any, the non-
compliance of such systems would have on the operation of the Managing
General Partnership or the operations of the Partnership.

1. Organization
Southwest Royalties Institutional Income Fund XI-A, L.P. was organized
under the laws of the state of Delaware on May 5, 1992, for the
purpose of acquiring producing oil and gas properties and to produce
and market crude oil and natural gas produced from such properties for
a term of 50 years, unless terminated at an earlier date as provided
for in the Partnership Agreement. The Partnership will sell its oil
and gas production to a variety of purchasers with the prices it
receives being dependent upon the oil and gas economy. Southwest
Royalties, Inc. serves as the Managing General Partner and H. H.
Wommack, III, as the individual general partner. Partnership profits
and losses, as well as all items of income, gain, loss, deduction, or
credit, will be credited or charged as follows:

Limited General

2. Summary of Significant Accounting Policies

Oil and Gas Properties
Oil and gas properties are accounted for at cost under the full-cost
method. Under this method, all productive and nonproductive costs
incurred in connection with the acquisition, exploration and
development of oil and gas reserves are capitalized. Gain or loss on
the sale of oil and gas properties is not recognized unless
significant oil and gas reserves are involved.

The Partnership's policy for depreciation, depletion and amortization
of oil and gas properties is computed under the units of revenue
method. Under the units of revenue method, depreciation, depletion
and amortization is computed on the basis of current gross revenues
from production in relation to future gross revenues, based on current
prices, from estimated production of proved oil and gas reserves.

Under the units of revenue method, the Partnership computes the
provision by multiplying the total unamortized cost of oil and gas
properties by an overall rate determined by dividing (a) oil and gas
revenues during the period by (b) the total future gross oil and gas
revenues as estimated by the Partnership's independent petroleum
consultants. It is reasonably possible that those estimates of
anticipated future gross revenues, the remaining estimated economic
life of the product, or both could be changed significantly in the
near term due to the potential fluctuation of oil and gas prices or
production. The depletion estimate would also be affected by this
change.

Should the net capitalized costs exceed the estimated present value of
oil and gas reserves, discounted at 10%, such excess costs would be
charged to current expense. As of December 31, 1997, the net
capitalized cost exceeded the estimated present value of oil and gas
reserves, thus an adjustment of $202,822 was made to the financial
statement. As December 31, 1996 and 1995, the net capitalized costs
did not exceed the estimated present value of oil and gas reserves.

The Partnership's interest in oil and gas properties consists of net
profits interests in proved properties located within the continental
United States. A net profits interest is created when the owner of a
working interest in a property enters into an arrangement providing
that the net profits interest owner will receive a stated percentage
of the net profit from the property. The net profits interest owner
will not otherwise participate in additional costs and expenses of the
property.

Notes to Financial Statements


2. Summary of Significant Accounting Policies - continued

Estimates and Uncertainties
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.

Organization Costs
Organization costs are stated at cost and are amortized over sixty
months using the straight-line method.

Syndication Costs
Syndication costs are accounted for as a reduction of partnership
equity.

Environmental Costs
The Partnership is subject to extensive federal, state and local
environmental laws and regulations. These laws, which are constantly
changing, regulate the discharge of materials into the environment and
may require the Partnership to remove or mitigate the environmental
effects of the disposal or release of petroleum or chemical substances
at various sites. Environmental expenditures are expensed or
capitalized depending on their future economic benefit. Costs which
improve a property as compared with the condition of the property when
originally constructed or acquired and costs which prevent future
environmental contamination are capitalized. Expenditures that relate
to an existing condition caused by past operations and that have no
future economic benefits are expensed. Liabilities for expenditures
of a non-capital nature are recorded when environmental assessment
and/or remediation is probable, and the costs can be reasonably
estimated.

Gas Balancing
The Partnership utilizes the sales method of accounting for gas-
balancing arrangements. Under this method, the Partnership recognizes
sales revenue on all gas sold. As of December 31, 1997 and 1996 the
Partnership was over produced by 3,521 and 2,974 mcf and under
produced by approximately 727 mcf at December 31, 1995.

Income Taxes
No provision for income taxes is reflected in these financial
statements, since the tax effects of the Partnership's income or loss
are passed through to the individual partners.

In accordance with the requirements of Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes," the
Partnership's tax basis in its net oil and gas properties at December
31, 1997 and 1996 is $136,512 and $3,089 more, respectively, as that
shown on the accompanying Balance Sheets in accordance with generally
accepted accounting principles.

Cash and Cash Equivalents
For purposes of the statements of cash flows, the Partnership
considers all highly liquid debt instruments purchased with a maturity
of three months or less to be cash equivalents. The Partnership
maintains its cash at one financial institution.

Number of Limited Partner Units
As of December 31, 1997, 1996 and 1995 there were 5,418 limited
partner units outstanding held by 221 partners.

Concentrations of Credit Risk
The Partnership is subject to credit risk through trade receivables.
Although a substantial portion of its debtors' ability to pay is
dependent upon the oil and gas industry, credit risk is minimized due
to a large customer base. All partnership revenues are received by
the Managing General Partner and subsequently remitted to the
partnership and all expenses are paid by the Managing General Partner
and subsequently reimbursed by the partnership.

Fair Value of Financial Instruments
The carrying amount of cash and accounts receivable approximates fair
value due to the short maturity of these instruments.

2. Summary of Significant Accounting Policies - continued

Recent Accounting Pronouncements
In June 1997, the FASB issued "Reporting Comprehensive Income," SFAS
No. 130, which establishes standards for reporting and display of
comprehensive income and its components in a full set of general-
purpose financial statements. Specifically, this statements requires
that an enterprise (i) classify items of other comprehensive income by
their nature in a financial statement and (ii) display the accumulated
balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the equity section of a
statement of financial position. This statement is effective for
fiscal years beginning after December 15, 1997. The Partnership
anticipates adoption of SFAS No. 130 in its year ended December 31,
1998 financial statements.

Comprehensive income consists of the change in equity of a business
enterprise during a period from transactions and other events and
circumstances from nonowner sources. Specifically, this includes net
income and other comprehensive income, which is made up of certain
changes in assets and liabilities that are not reported in a statement
of operations but are included in the balances within a separate
component of equity in a statement of financial position. Such
changes include, but are not limited to, unrealized gains for
marketable securities and futures contracts, foreign currency
translation adjustments and minimum pension liability adjustments.

Net Income (loss) per limited partnership unit
The net income (loss) per limited partnership unit is calculated by
using the number of outstanding limited partnership units.

3. Commitments and Contingent Liabilities
The Managing General Partner has the right, but not the obligation, to
purchase limited partnership units should an investor desire to sell.
The value of the unit is determined by adding the sum of (1) current
assets less liabilities and (2) the present value of the future net
revenues attributable to proved reserves and by discounting the future
net revenues at a rate not in excess of the prime rate charged by
NationsBank, N.A. of Midland, Texas plus one percent (1%), which value
shall be further reduced by a risk factor discount of no more than one-
third (1/3) to be determined by the Managing General Partner in its
sole and absolute discretion.

The Partnership is subject to various federal, state and local
environmental laws and regulations which establish standards and
requirements for protection of the environment. The Partnership
cannot predict the future impact of such standards and requirements,
which are subject to change and can have retroactive effectiveness.
The Partnership continues to monitor the status of these laws and
regulations.

3. Commitments and Contingent Liabilities - continued
As of December 31, 1997, the Partnership has not been fined, cited or
notified of any environmental violations and management is not aware
of any unasserted violations which would have a material adverse
effect upon capital expenditures, earnings or the competitive position
in the oil and gas industry. However, the Managing General Partner
does recognize by the very nature of its business, material costs
could be incurred in the near term to bring the Partnership into total
compliance. The amount of such future expenditures is not reliably
determinable due to several factors, including the unknown magnitude
of possible contaminations, the unknown timing and extent of the
corrective actions which may be required, the determination of the
Partnership's liability in proportion to other responsible parties and
the extent to which such expenditures are recoverable from insurance
or indemnifications from prior owners of Partnership's properties.

4. Related Party Transactions
A significant portion of the oil and gas properties in which the
Partnership has an interest are operated by and purchased from the
Managing General Partner. As is usual in the industry and as provided
for in the operating agreement for each respective oil and gas
property in which the Partnership has an interest, the operator is
paid an amount for administrative overhead attributable to operating
such properties, with such amounts to Southwest Royalties, Inc. as
operator approximating $70,000, $73,000 and $65,000 for the years
ended December 31, 1997, 1996 and 1995, respectively. In addition,
the Managing General Partner and certain officers and employees may
have an interest in some of the properties that the Partnership also
participates.

Certain subsidiaries or affiliates of the Managing General Partner
perform various oilfield services for properties in which the
Partnership owns an interest. Such services aggregated approximately
$500, $2,400 and $3,300 for the years ended December 31, 1997, 1996
and 1995, respectively and the Managing General Partner believes that
these costs are comparable to similar charges paid by the Partnership
to unrelated third parties.

Southwest Royalties, Inc., the Managing General Partner, was paid
$42,000 during 1997, 1996 and 1995, as an administrative fee for
indirect general and administrative overhead expenses.

Receivables from Southwest Royalties, Inc., the Managing General
Partner, of approximately $85,473 and $118,399 are from oil and gas
production, net of lease operating costs and production taxes, as of
December 31, 1997 and 1996.

In addition, a director and officer of the Managing General Partner is
a partner in a law firm, with such firm providing legal services to
the Partnership approximating $30, $120 and none for the years ended
December 31, 1997, 1996 and 1995, respectively.

5. Major Customers
No material portion of the Partnership's business is dependent on a
single purchaser, or a very few purchasers, where the loss of one
would have a material adverse impact on the Partnership. Two
purchasers accounted for 37% of the Partnership's total oil and gas
production during 1997: American Processing 24%, and Navajo Refining
Company, Inc. 13%. Three purchasers accounted for 47% of the
Partnership's total oil and gas production during 1996: American
Processing 20%, Navajo Refining Company, Inc. 14% and Torch Operating
Company 13%. Three purchasers accounted for 50% of the Partnership's
total oil and gas production during 1995: American Processing, Navajo
Refining Company and Nustar Joint Venture purchased 20%, 15% and 15%,
respectively. All purchasers of the Partnership's oil and gas
production are unrelated third parties. In the event any of these
purchasers were to discontinue purchasing the Partnership's
production, the Managing General Partner believes that a substitute
purchaser or purchasers could be located without undue delay. No
other purchaser accounted for an amount equal to or greater than 10%
of the Partnership's sales of oil and gas production.

All of the Partnership's reserves are located within the continental
United States.

*The reserve estimates were prepared as of January 1, 1998, by Donald
R. Creamer, P.E., an independent registered petroleum engineer. The
reserve estimates were made in accordance with guidelines established
by the Securities and Exchange Commission pursuant to Rule 4-10(a) of
Regulation S-X. Such guidelines require oil and gas reserve reports
be prepared under existing economic and operating conditions with no
provisions for price and cost escalation except by contractual
arrangements.

The New York Mercantile Exchange price at December 31, 1997 of $17.64
was used as the beginning basis for the oil price. Oil price
adjustments from $17.64 per barrel were made in the individual
evaluations to reflect oil quality, gathering and transportation
costs. The results are an average price received at the lease of
$16.09 per barrel in the preparation of the reserve report as of
January 1, 1998.

In the determination of the gas price, the New York Mercantile
Exchange price at December 31, 1997 of $2.26 was used as the beginning
basis. Gas price adjustments from $2.26 per Mcf were made in the
individual evaluations to reflect BTU content, gathering and
transportation costs and gas processing and shrinkage. The results
are an average price received at the lease of $2.12 per Mcf in the
preparation of the reserve report as of January 1, 1998.

The evaluation of oil and gas properties is not an exact science and
inevitably involves a significant degree of uncertainty, particularly
with respect to the quantity of oil or gas that any given property is
capable of producing. Estimates of oil and gas reserves are based on
available geological and engineering data, the extent and quality of
which may vary in each case and, in certain instances, may prove to be
inaccurate. Consequently, properties may be depleted more rapidly
than the geological and engineering data have indicated.

Notes to Financial Statements


6. Estimated Oil and Gas Reserves (unaudited) - continued

Unanticipated depletion, if it occurs, will result in lower reserves
than previously estimated; thus an ultimately lower return for the
Partnership. Basic changes in past reserve estimates occur annually.
As new data is gathered during the subsequent year, the engineer must
revise his earlier estimates. A year of new information, which is
pertinent to the estimation of future recoverable volumes, is
available during the subsequent year evaluation. In applying industry
standards and procedures, the new data may cause the previous
estimates to be revised. This revision may increase or decrease the
earlier estimated volumes. Pertinent information gathered during the
year may include actual production and decline rates, production from
offset wells drilled to the same geologic formation, increased or
decreased water production, workovers, and changes in lifting costs,
among others. Accordingly, reserve estimates are often different from
the quantities of oil and gas that are ultimately recovered.

The Partnership has reserves which are classified as proved developed
producing, proved developed non-producing and proved undeveloped. All
of the proved reserves are included in the engineering reports which
evaluate the Partnership's present reserves.

Because the Partnership does not engage in drilling activities, the
development of proved undeveloped reserves is conducted pursuant to
farm-out arrangements with the Managing General Partner or unrelated
third parties. Generally, the Partnership retains a carried interest
such as an overriding royalty interest under the terms of a farm-out,
or receives cash.

Item 9. Changes in and Disagreements With Accountants on Accounting and
Financial Disclosure

On June 9, 1997 Southwest Royalties, Inc. the Partnership's Managing
General Partner (Southwest Royalties, Inc.) dismissed Joseph Decosimo and
Company as the Partnership's independent accountants. The Managing General
Partner's Board of Directors approved the decision to change the
Partnership's independent accountants.

The reports of Joseph Decosimo and Company on the financial statements for
the past two fiscal years contained no adverse opinion or disclaimer of
opinion and were not qualified or modified as to uncertainty, audit scope
or accounting principle.

In connection with its audits for the two most recent fiscal years and
through June 9, 1997, there have been no disagreements with Joseph Decosimo
and Company on any matter of accounting principles or practices, financial
statements disclosure, or auditing scope or procedure, which disagreements
if not resolved to the satisfaction of Joseph Decosimo and Company would
have caused them to make reference thereto in their report on the financial
statements for such years.

The Registrant has requested that Joseph Decosimo and Company furnish it
with a letter addressed to the SEC stating whether or not is agrees with
the above statements. A copy of that letter is included as Exhibit 16 and
has been filled with the Securities and Exchange Commission.

Partnership's limited partnership interests.

The Managing General Partner owns a nine percent interest in the
Partnership as a general partner. Through prior purchases, the Managing
General Partner also owns 326 limited partner units, or 6.0% limited
partner interest. The Managing General Partner total percentage interest
ownership in the Partnership is 14.4%.

No officer or director of the Managing General Partner owns Units in the
Partnership. H. H. Wommack, III, as the individual general partner of the
Partnership, owns a one percent interest as a general partner. The
officers and directors of the Managing General Partner are considered
beneficial owners of the limited partner units acquired by the Managing
General Partner by virtue of their status as such. A list of beneficial
owners of limited partner units, acquired by the Managing General Partner,

Item 13. Certain Relationships and Related Transactions

In 1997, the Managing General Partners received $42,000 as an
administrative fee. This amount is part of the general and administrative
expenses incurred by the Partnership.

In some instances the Managing General Partner and certain officers and
employees may be working interest owners in an oil and gas property in
which the Partnership also has a working interest. Certain properties in
which the Partnership has an interest are operated by the Managing General
Partner, who was paid approximately $70,000 for administrative overhead
attributable to operating such properties during 1997.

Certain subsidiaries or affiliates of the Managing General Partner perform
various oilfield services for properties in which the Partnership owns an
interest. Such services aggregated approximately $500 for the year ended
December 31, 1997.

In the opinion of management, the terms of the above transactions are
similar to ones with unaffiliated third parties.
