Item 1.   Business

General
Southwest Oil & Gas Income Fund X-A, L.P. (the "Partnership" or "Registrant")
was organized as a Delaware limited partnership on January 29, 1990.  The
offering of limited partnership interests began May 11, 1990 as part of a
shelf offering registered under the name Southwest Oil & Gas 1990-91 Income
Program (the "Program").  Minimum capital requirements for the Partnership
were met on August 15, 1990, with the offering of limited partnership
interests concluding on November 30, 1990.  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 working interests in
oil and gas properties.  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 245 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 working interests in oil and gas
properties located in New Mexico 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.

<PAGE>
<PAGE>
The recent strength in the price of crude oil reflects a continued growth in
demand for energy.  The worldwide demand for oil continues to grow.  The
United States dependence on foreign oil reached a record 51% in 1996.  The
supply of oil is not keeping up with the demand on either a domestic or
worldwide economic basis.  Oil production in the United States fell for the
fifth straight year, dropping 1.8% to 6.45 million barrels per day in 1996. 
At the same time, economic recovery in the world economy continues to apply
upward pressure on demand.  Current oil consumption of over 70 million
barrels per day is growing on an annual basis.  This is especially acute in
the lesser developed countries as they move toward industrialization.  Supply
and demand for oil has moved very close to being in balance.  The lack of
excess capacity in the oil markets has helped push oil prices into the mid-
20's during 1996.

For the last several years, the natural gas industry in the United States has
been affected generally by a surplus in available natural gas and enhanced
delivery capability causing a general deterioration in natural gas prices. 
In 1996, natural gas prices recovered significantly after having been
adversely affected for many years by the chronic oversupply.  A colder than
normal 1995 and 1996 winter for most of the nation and a cold start for the
1996 and 1997 heating season has increased demand, while supplies have
declined creating a guarded optimism within the industry in regards to the
1997 gas price.  January 1997's gas price is the highest the industry has
seen since deregulation in 1985.

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

                                  Oil          Gas 

                    1996          91%           9%
                    1995          92%           8%
                    1994          90%          10% 


As the table indicates, the majority of the Partnership's revenue is from its
oil production; therefore, Partnership revenues will be highly dependent upon
the future prices and demands for oil.

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.

<PAGE>
<PAGE>
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.  Four purchasers accounted for
83% of the Partnership's total oil and gas production during 1996:  Scurlock
Permian Corporation 36%, Anadarko Petroleum Corporation 22%, Navajo Refining
Company, Inc. 14% and Mobil Corporation 11%.  Three purchasers accounted for
76% of the Partnership's total oil and gas production during 1995:  Scurlock
Permian Corporation, Navajo Refining Company, Inc. and Mobil Corporation
purchased 47%, 15% and 14%, respectively.  Four purchasers accounted for 76%
of the Partnership's total oil and gas production during 1994:  Scurlock
Permian Corporation, Navajo Refining Company, Inc., Mobil Corporation and
Anadarko Petroleum Corporation purchased 41%, 12%, 12% and 11%, 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
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 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.

<PAGE>
<PAGE>
Various aspects of the Partnership's oil and gas activities are 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 are 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 - Certain 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, 1996, there
were 245 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, 1996, the Partnership possessed an interest in oil and gas
properties located in Eddy and Lea Counties of New Mexico; Culberson, DeWitt,
Duval, Gaines, Hockley, Lamb, Matagorda, Midland, Pecos, Runnels, Terry,
Upton and Ward Counties of Texas.  These properties consist of various
interests in approximately 176 wells and units.

<PAGE>
<PAGE>
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 1996, 1995 and 1994.

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 1996, three leases were sold for $1,050.  The JH King was sold
effective August 1996 and the Fair-Wendt and CW Hahl were sold effective
December 1996.

During 1995, three leases were sold for approximately $55,800.  The Zahn was
sold effective September 1995 and the Meeker and Slouson were sold effective
November 1995.

During 1994, three leases were sold for approximately $334,600.  The Caddell,
Cook #1 and Cook #2 were sold effective January 1994.

Significant Properties
The following table reflects the significant properties in which the
Partnership has an interest:

*Per the terms of the purchase, the Partnership received production runs from
a period prior to the date of purchase.

<PAGE>
<PAGE>
*The reserve estimates were prepared as of January 1, 1997, 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 operation conditions, price and costs, as of the date
the estimation is made.  Prices may include consideration of changes in
existing price provided only by contractual arrangements, but not on
escalations based upon future conditions.
 
An oil price of $23.83 per barrel was used in the preparation of the reserve
report as of January 1, 1997.  The West Texas Intermediate posted price at
December 31, 1996 of $24.25 was used as the beginning basis for the oil
price.  Oil price adjustments from $24.25 per barrel were made in the
individual evaluations to allow for the average difference between recent
prices actually received (current prices) and the West Texas Intermediate
posted price on the sales date.  This effectively adjusts for temperature,
gravity, transportation and impurities on an individual property basis to
arrive at a fair value for the selling price.

A gas price of $4.16 per mcf was used in the preparation of the reserve
report as of January 1, 1997.  The El Paso Permian Basin Index posted price
at December 31, 1996 of $3.59 was used as the beginning basis for the gas
price.  Gas price adjustments from $3.59 per mcf were made in the individual
evaluations to allow for the average difference between recent prices
actually received (current prices) and the El Paso Permian Basin Index posted
price on the sales date.  This effectively adjusts for temperature, gravity,
transportation and impurities on an individual property basis to arrive at a
fair value for the selling price.

As also discussed in Part II, Item 7, Management's Discussion and Analysis of
Financial Condition and Results of Operations, oil and gas prices were
subject to frequent changes in 1996.

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.  

<PAGE>
<PAGE>
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 in 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 1996 through the solicitation of proxies or otherwise.

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 1996, 32 limited
partner units were tendered to and purchased by the Managing General Partner
at an average base price of $201.93 per unit.  As of December 31, 1995 and
1994, no limited partner units were purchased by the Managing General
Partner.

Number of Limited Partner Interest Holders
As of December 31, 1996, there were 572 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" is 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) Operating Costs,
and (iii) any reserves necessary to meet current and anticipated needs of the
Partnership, as determined in the sole discretion of the Managing General
Partner."  

<PAGE>
<PAGE>
During 1996, twelve monthly distributions were made totaling $153,000, with
$137,700 distributed to the limited partners and $15,300 to the general
partners.  For the year ended December 31, 1996, distributions of $13.13 per
limited partner unit were made, based upon 10,484 limited partner units
outstanding.  During 1995, twelve monthly distributions were made totaling
$98,039, with $89,939 distributed to the limited partners and $8,100 to the
general partners.  For the year ended December 31, 1995, distributions of
$8.58 per limited partner unit were made, based on 10,484 limited partner
units outstanding.  During 1994, twelve monthly distributions were made
totaling $485,848, with $457,953 distributed to the limited partners and
$27,895 to the general partners.  For the year ended December 31, 1994,
distributions of $43.68 per limited partner unit were made, based on 10,484
limited partner units outstanding.

Item 6.   Selected Financial Data

The following selected financial data for the years ended December 31, 1996,
1995, 1994, 1993, and 1992 should be read in conjunction with the financial

          Results of Operations

General
The Partnership was formed to acquire 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 are not 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 thus depends 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 of 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 is therefore expected to fluctuate in later years based on these
factors.

Based on current conditions, management anticipates participating in a
farmout agreement and performing workovers during the next two years to
enhance production.  The Partnership may undergo an increase later in 1997
and possibly in 1998.  Thereafter, the Partnership could possibly experience
a normal decline of 8% to 10% per year.

Results of Operations

A.   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

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

Average price per barrel of oil          $    19.53     16.28      20%
Average price per mcf of gas             $     2.54      2.08      22%
Oil production in barrels                    38,000    33,000      15%
Gas production in mcf                        29,200    23,800      23%
Gross oil and gas revenue                $  816,345   587,070      39%

Revenues

The Partnership's oil and gas revenues increased to $816,345 from $587,070
for the years ended December 31, 1996 and 1995, respectively, an increase of
39%.  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 20%, or $3.25 per barrel, resulting in an
    increase of approximately $107,300 in revenues.  Oil sales represented
    91% of total oil and gas sales during the year ended December 31, 1996 as
    compared to 92% 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 22%, or $.46 per mcf, resulting in an increase
    of approximately $10,900 in revenues.  

    The total increase in revenues due to the change in prices received from
    oil and gas production is approximately $118,200.  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.

<PAGE>
<PAGE>
2.  Oil production increased approximately 5,000 barrels or 15% during the
    year ended December 31, 1996 as compared to the year ended December 31,
    1995, resulting in an increase of approximately $97,700 in revenues.

    Gas production increased approximately 5,400 mcf or 23% during the same
    period, resulting in an increase of approximately $13,700 in revenues.

    The total increase in revenues due to the change in production is
    approximately $111,400.

3.  Subsequent to December 31, 1996, the Partnership received $14,850 from a
    lawsuit settlement between Scana Petroleum, the oil and gas purchaser for
    the Ethel Cornelius lease, and the lease's operator, Alltex Exploration,
    concerning pricing. 

Costs and Expenses

Total costs and expenses decreased to $658,558 from $685,773 for the years
ended December 31, 1996 and 1995, respectively, a decrease of 4%.  The
decrease is the result of lower general and administrative expense and
depletion expense, offset by an increase in lease operating expense.

1.  Lease operating costs and production taxes were less than 1% higher, or
    approximately $1,700 more during the year ended December 31, 1996 as
    compared to the year ended December 31, 1995.  

2.  General and administrative costs consist of independent accounting and
    engineering fees, computer services, postage, and Managing General
    Partner personnel costs.  General and administrative costs decreased 3%
    or approximately $2,400 during the year ended December 31, 1996 as
    compared to the year ended December 31, 1995.

3.  Depletion expense decreased to $57,000 for the year ended December 31,
    1996 from $79,000 for the same period in 1995.  This represents a
    decrease of 28%.  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 was 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 $31,000 as of December 31, 1995.

B.  General Comparison of the Years Ended December 31, 1995 and 1994

The following table provides certain information regarding performance
factors for the years ended December 31, 1995 and 1994:

                                              Year Ended        Percentage
                                              December 31,       Increase
                                             1995      1994     (Decrease)
                                             ----      ----     ----------

Average price per barrel of oil          $    16.28     14.67      11%
Average price per mcf of gas             $     2.08      1.90       9%
Oil production in barrels                    33,000    48,700     (32%)
Gas production in mcf                        23,800    44,000     (46%)
Gross oil and gas revenue                $  587,070   798,089     (26%)
Net oil and gas revenue                  $   75,107   240,305     (69%)
Partnership distributions                $   98,039   485,848     (80%)
Limited partner distributions            $   89,939   457,953     (80%)
Per unit distribution to limited
 partners                                $     8.58     43.68     (80%)
Number of limited partner units              10,484    10,484

Revenues

The Partnership's oil and gas revenues decreased to $587,070 from $798,089
for the years ended December 31, 1995 and 1994, respectively, a decrease of
26%.  The principal factors affecting the comparison of the years ended
December 31, 1995 and 1994 are as follows:

1.   The average price for a barrel of oil received by the Partnership
     increased during the year ended December 31, 1995 as compared to the
     year ended December 31, 1994 by 11%, or $1.61 per barrel, resulting in
     an increase of approximately $78,400 in revenue.  Oil sales represented
     92% of total oil and gas sales during the year ended December 31, 1995
     as compared to 90% during the year ended December 31, 1994.

     The average price received for an mcf of gas received by the Partnership
     increased during the same period by 9%, or $.18 per mcf, resulting in an
     increase of approximately $7,900 in revenue.  

     The total increase in revenue due to the change in prices received from
     oil and gas production is approximately $86,300.  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 15,700 barrels or 32% during the
     year ended December 31, 1995 as compared to the year ended December 31,
     1994, resulting in a decrease of approximately $255,600 in revenue.

<PAGE>
<PAGE>
     Gas production decreased approximately 20,200 mcf or 46% during the same
     period, resulting in a decrease of approximately $42,000 in revenue.

     The total decrease in revenue due to the change in production is
     approximately $297,600. The decrease is primarily attributable to
     property sales and mechanical failures in 1995.

Costs and Expenses

Total costs and expenses decreased to $685,773 from $770,957 for the years
ended December 31, 1995 and 1994, respectively, a decrease of 11%.  The
decline is the result of a decrease in production costs, general and
administrative expense and depletion.

1.   Lease operating costs and production taxes were 8% lower, or
     approximately $45,800 less during the year ended December 31, 1995 as
     compared to the year ended December 31, 1994.  The decrease is a result
     of the property sales and workover costs incurred in 1994.

2.   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 2%
     or approximately $2,300 during the year ended December 31, 1995 as
     compared to the year ended December 31, 1994. 

3.   Depletion expense decreased to $79,000 for the year ended December 31,
     1995 from $113,000 for the same period in 1994.  This represents a
     decrease of 30%.  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.  Consequently,
     depletion will fluctuate in direct relation to oil and gas revenues.  As
     noted above, oil and gas revenues declined due to a decline in oil and
     gas production for the year ended December 31, 1995 as compared to the
     same period for 1994.  Depletion reflected a comparable decline.

<PAGE>
C.   Revenue and Distribution Comparison

Partnership income or (loss) for the years ended December 31, 1996, 1995 and
1994 was $173,666 in 1996, $(97,954) in 1995 and $30,123 in 1994.  Excluding
the effects of depreciation, depletion and amortization, net income or (loss)
would have been $230,666 in 1996, $(14,467) in 1995 and $150,683 in 1994. 
Correspondingly, Partnership distributions for the years ended December 31,
1996, 1995 and 1994 were $153,000, $98,039 and $485,848, respectively.  These
differences are indicative of the changes in oil and gas prices, production
and property sales.

The sources for the 1996 distributions of $153,000 were oil and gas
operations of $132,800 and property sales of approximately $1,300, offset by
additions to oil and gas properties of approximately $13,500, with the
balance from available cash on hand at the beginning of the period.  The
sources for the 1995 distributions of $98,039 were oil and gas operations of
approximately $52,100 and property sales of $59,800, offset by additions to
oil and gas properties of approximately $8,500, resulting in excess cash for
contingencies or subsequent distributions.  The sources for the 1994
distributions of $485,848 were oil and gas operations of approximately
$153,400 and property sales of approximately $341,100, offset by additions to
oil and gas properties of approximately $5,300, resulting in excess cash for
contingencies or subsequent distribution.    
     
Total distributions during the year ended December 31, 1996 were $153,000 of
which $137,700 was distributed to the limited partners and $15,300 to the
general partners. The per unit distribution to limited partners during the
same period was $13.13.  Total distributions during the year ended December
31, 1995 were $98,039 of which $89,939 was distributed to the limited
partners and $8,100 to the general partners.  The per unit distribution to
limited partners during the same period was $8.58.  Total distributions
during the year ended December 31, 1994 were $485,848 of which $457,953 was
distributed to the limited partners and $27,895 to the general partners.  The
per unit distribution to limited partners during the same period was $43.68.

Since inception of the Partnership, cumulative monthly cash distributions of
$2,488,906 have been made to the partners.  As of December 31, 1996,
$2,290,484 or $218.47 per limited partner unit, has been distributed to the
limited partners, representing a 44% return of the capital contributed.

<PAGE>
Liquidity and Capital Resources

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

Cash flows provided by operating activities were approximately $132,800 in
1996 compared to approximately $52,100 in 1995 and approximately $153,400 in
1994.  The primary source of the 1996 cash flow from operating activities was
profitable operations.

Cash flows provided by or (used in) investing activities were approximately
$(12,100) in 1996 compared to approximately $51,300 in 1995 and approximately
$335,800 in 1994.  The principal use of the 1996 cash flow from investing
activities was the additions to oil and gas properties, offset by the sale of
oil and gas properties.

Cash flows used in financing activities were approximately $152,800 in 1996
compared to approximately $98,300 in 1995 and approximately $485,400 in 1994. 
The only use in the 1996 financing activities was the distributions to
partners.

As of December 31, 1996, the Partnership had approximately $108,186 in
working capital.  The Managing General Partner knows of no unusual
contractual commitments and believes the revenues generated from operations
are adequate to meet the needs of the Partnership.

                       Notes to Financial Statements


1.   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, 1996, 1995 and 1994 the
     net capitalized costs did not exceed the estimated present value of oil
     and gas reserves.

     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.

                       Notes to Financial Statements


     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, 1996, 1995 and 1994,
     there were no significant amounts of imbalance in terms of units and
     value.

     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, 1996 and 1995 is
     $180,942 and $470,360, respectively, more than that shown on the
     accompanying Balance Sheets in accordance with generally accepted
     accounting principles.

     Cash and Cash Equivalents
     For purposes of the statement 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.

     All of the Partnership's properties were proved when acquired.

4.   Commitments and Contingent Liabilities
     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.

     As of December 31, 1996, 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.

5.   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
     $67,500, $64,000 and $74,000 for the years ended December 31, 1996, 1995
     and 1994, 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 of the Managing General Partner perform various
     oilfield services for properties in which the Partnership owns an
     interest.  Such services aggregated approximately $600, $4,000 and 
     $7,000 for the years ended December 31, 1996, 1995 and 1994,
     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
     $78,000 during 1996, 1995 and 1994 for indirect general and
     administrative overhead expenses.

     Receivables from Southwest Royalties, Inc., the Managing General
     Partner, of approximately $85,367 and $2,318 are from oil and gas
     production, net of lease operating costs and production taxes, as of
     December 31, 1996 and 1995, respectively.

     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 $70, for the year ended December 31, 1996. 
     There were no legal services provided for the year ended December 31,
     1995 and approximately $100 for the year ended December 31, 1994.

6.   Major Customers and Significant Leases
     During 1996, four customers purchased 36%, 22%, 14% and 11% of the
     Partnership's oil and gas production.  During 1995, three customers
     purchased 47%, 15% and 14% of the Partnership's oil and gas production. 
     During 1994, four customers purchased 41%, 12%, 12% and 11% of the
     Partnership's oil and gas production.  

     During 1996, one lease accounted for 23% of the Partnership's gross
     revenue.

8.   Subsequent Events
     The Partnership was carried into a project on the Ballard Grayburg San
     Andres Unit to drill five infill producers.  An evaluation, prepared by
     an independent certified petroleum engineer, of the proposed infill
     drilling to determine a fair arrangement for the Partnership to
     participate has resulted in a farm-out agreement with Southwest
     Royalties, Inc., the Managing General Partner, to pay all the
     Partnership's costs in the proposed drilling in return for a working
     interest equal to 90% of the Partnership's combined working interest in
     the Ballard Grayburg San Andres Unit, effective January 1, 1997.

utilization of such consultants and independent contractors in specific
instances and on an "as-needed" basis allows for greater flexibility and
greater opportunity to perform its oil and gas activities more economically
and effectively.

Item 11.  Executive Compensation

The Partnership does not have any directors or executive officers.  The
executive officers of the Managing General Partner do not receive any cash
compensation, bonuses, deferred compensation or compensation pursuant to any
type of plan, from the Partnership.  The Managing General Partners received
$78,000 during 1996, 1995 and 1994 as an annual administrative fee.

Item 12.  Security Ownership of Certain Beneficial Owners and Management

There are no limited partners who own of record, or are known by the Managing
General Partner to beneficially own, more than five percent of the
Partnership's limited partnership interests.

The Managing General Partner owns a nine percent interest as a general
partner.  Through prior purchases, the Managing General Partner also owns 32
limited partner units, or a .31% limited partner interest.  The Managing
General Partner total percentage interest ownership in the Partnership is
9.3%.

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

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, is as follows:

There are no arrangements known to the Managing General Partner which may at
a subsequent date result in a change of control of the Partnership.

Item 13.  Certain Relationships and Related Transactions

In 1996, the Managing General Partner received $78,000 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 $67,500 for administrative overhead attributable to
operating such properties during 1996.

Certain subsidiaries of the Managing General Partner perform various oilfield
services for properties in which the Partnership owns an interest.  Such
services aggregated approximately $600 for the year ended December 31, 1996.

The law firm of Miller & Martin, of which H. Allen Corey, an officer and
director of the Managing General Partner, is a partner, is counsel to the
Partnership.  Legal services rendered by Miller & Martin to the Partnership
during 1996 were approximately $70, which constitutes an immaterial portion
of that firm's business.  Subsequent to December 31, 1996, the counsel to the
Partnership, H. Allen Corey, became a partner in the law firm Baker,
Donelson, Bearman & Caldwell.

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