                                  Part I


Item 1.   Business

General
Southwest  Oil  &  Gas  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 on August  20,
1992,  as  part of a shelf offering registered under the name of  Southwest
Oil  & Gas 1992-93 Income Program, reached minimum capital requirements  on
March  17,  1993  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 nonoperating 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  89  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  working
interests  in oil and gas properties located in Alabama, Kansas, Louisiana,
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.


For  nearly nine months, despite the fears of a global recession, crude oil
prices  held steady between $26 and $28 per barrel due in part to a  series
of  OPEC  and  non-OPEC production cuts.  Then, following what  has  become
known  simply  as  "9-11",  crude prices plunged  immediately  to  $22  and
gradually  fell  to below $18 per barrel.  Slower demand  across  the  U.S.
caused by the threat of recession and warmer than expected weather also led
to  declining prices in the latter half of 2001.  However, the  oil  cartel
and other non-member countries agreed for the fourth time since February to
curb  output in an effort to stabilize prices.  Crude oil contracts trading
on the NYMEX closed the year at approximately $20 per barrel.

Spot  prices in 2001 climbed to their highest levels ever, with the  yearly
average  price  nationwide reaching $4.14/MMBtu, up  9.77%  from  the  2000
average  of $3.77/MMBtu.  Prices reached their zenith in the first  quarter
of  2001 before beginning a steady decline throughout the remainder of  the
year.   The  terrorist  attacks  of  September  11  knocked  the  New  York
Mercantile Exchange out of the market for several days and shook  the  spot
marketplace into a maintenance mode.  As companies measured the  impact  of
the  attacks on the U.S. economy, spot prices deteriorated further.  In the
fourth  quarter,  prices  bottomed out for the year  with  the  three-month
average  falling to $2.31/MMBtu.  As for 2002, record-high  storage  levels
and  the  expectation of a flat economy through the first half of the  year
are  leading  industry  experts to predict prices to  average  $2.05/MMBtu,
remaining above the $2.00 per MMBtu level for a 5th consecutive year.

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

                                  Oil          Gas

                    2001          38%          62%
                    2000          40%          60%
                    1999          41%          59%

As  the table indicates, the Partnership's revenue is almost evenly divided
between its oil and gas production; therefore, 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.  Five purchasers accounted  for
85%  of  the Partnership's total oil and gas production during  2001:   Sid
Richardson  Energy  Services for 26%, Duke Energy Field Services  for  17%,
Phillips  66  Company  for 17%, Sap Acquisition Corporation  for  15%,  and
Navajo  Refining Company, Inc. for 10%.  Four purchasers accounted for  76%
of  the  Partnership's  total  oil and gas  production  during  2000:   Sid
Richardson  Gasoline  Co.  for 21%, Phillips 66  Company  for  33%,  Navajo
Refining  Company Inc. for 11% and Southwestern Energy Production  Co.  for
11%.  Four purchasers accounted for 75% of the Partnership's total oil  and
gas  production  during  1999: Phillips 66 Company  for  30%,  Southwestern
Energy  Production Co. for 19%, Sid Richardson Gasoline  Co.  for  16%  and
Navajo Refining Co., Inc. for 10%.  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 interests in producing oil and gas properties  or  drilling
operations,  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 - 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,
2001,  there were 89 individuals directly employed by the Managing  General
Partner in various capacities.

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.


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, 2001, the Partnership possessed an interest in oil  and
gas  properties located in Escambia and Lamar Counties of Alabama;  Labette
and  Neosho  Counties  of Kansas; La Fourche, Pointe Coupe  and  Terrebonne
Parishes  of Louisiana; Eddy County of New Mexico; Custer, Roger Mills  and
Washita Counties of Oklahoma; and Dickens, Hemphill, Live Oak, Upton, Ward,
Winkler  and Yoakum Counties of Texas.  These properties consist of various
interests in 101 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 2001, 2000 and 1999.

There were no property sales during 2001, 2000 and 1999

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

*Ryder  Scott  Petroleum Engineers prepared the reserve and  present  value
data for the Partnership's existing properties as of January 1, 2002.   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.


Oil  price  adjustments were made in the individual evaluations to  reflect
oil quality, gathering and transportation costs. The results of the reserve
report as of January 1, 2002 are an average price of $17.14 per barrel.

Gas  price  adjustments were made in the individual evaluations to  reflect
BTU  content,  gathering and transportation costs and  gas  processing  and
shrinkage.  The results of the reserve report as of January 1, 2002 are  an
average price of $2.03 per Mcf.

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 2001.

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 farmout
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 farmout, 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 2001 through the solicitation of proxies or otherwise.

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

Market Information
Limited  partnership interest, 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.   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
2001,  10  limited  partner units were tendered to  and  purchased  by  the
Managing General Partner at an average base price of $115.65 per unit.   In
2000,  10  limited  partner units were tendered to  and  purchased  by  the
Managing  General Partner at an average base price of $79.77 per unit.   As
of  December  31,  1999,  no limited partner units were  purchased  by  the
Managing General Partner.

Number of Limited Partner Interest Holders
As of December 31, 2001, there were 120 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 quarterly 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  2001,  distributions  were made totaling  $142,545,  with  $128,291
distributed  to  the limited partners and $14,254 to the general  partners.
For  the  year ended December 31, 2001, distributions of $45.48 per limited
partner unit were made, based upon 2,821 limited partner units outstanding.
During  2000,  quarterly  distributions were made totaling  $105,130,  with
$94,617  distributed  to the limited partners and $10,513  to  the  general
partners.   For the year ended December 31, 2000, distributions  of  $33.54
per  limited partner unit were made, based upon 2,821 limited partner units
outstanding.  During 1999, distributions were made totaling $109,407,  with
$100,907  distributed  to the limited partners and $8,500  to  the  general
partners.   For the year ended December 31, 1999, distributions  of  $35.77
per  limited partner unit were made, based upon 2,821 limited partner units
outstanding.

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

General
Southwest  Oil  &  Gas  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 on August  20,
1992 as part of a shelf offering registered under the name of Southwest Oil
&  Gas  1992-93  Income  Program.  Minimum  capital  requirements  for  the
Partnership  were met on March 17, 1993 and the Offering Period  terminated
April  30,  1993  with  120  limited partners purchasing  2,821  units  for
$1,410,500.

The Partnership was formed to acquire 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 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 performing no workovers
during  2002 to enhance production.  Additional workovers may be  performed
in  the  year  2003.   The partnership may have an increase  in  production
volumes  for  the  year 2003, otherwise, the partnership will  most  likely
experience the historical production decline of approximately 8% per year.

Critical Accounting Policies
Full cost ceiling calculations The Partnership follows the full cost method
of  accounting  for  its  oil and gas properties.   The  full  cost  method
subjects  companies to quarterly calculations of a "ceiling", or limitation
on  the  amount of properties that can be capitalized on the balance sheet.
If  the  Partnership's capitalized costs are in excess  of  the  calculated
ceiling, the excess must be written off as an expense.

The  Partnership's discounted present value of its proved oil  and  natural
gas  reserves  is  a  major  component  of  the  ceiling  calculation,  and
represents  the  component  that requires the  most  subjective  judgments.
Estimates  of  reserves are forecasts based on engineering data,  projected
future  rates  of  production and the timing of future  expenditures.   The
process  of  estimating oil and natural gas reserves  requires  substantial
judgment,  resulting  in  imprecise determinations,  particularly  for  new
discoveries.   Different reserve engineers may make different estimates  of
reserve  quantities  based  on the same data.   The  Partnership's  reserve
estimates are prepared by outside consultants.

The  passage  of  time  provides  more  qualitative  information  regarding
estimates of reserves, and revisions are made to prior estimates to reflect
updated  information.   However,  there  can  be  no  assurance  that  more
significant  revisions  will not be necessary in  the  future.   If  future
significant  revisions  are  necessary  that  reduce  previously  estimated
reserve quantities, it could result in a full cost property writedown.   In
addition to the impact of these estimates of proved reserves on calculation
of  the  ceiling,  estimates  of proved reserves  are  also  a  significant
component of the calculation of DD&A.



While  the quantities of proved reserves require substantial judgment,  the
associated prices of oil and natural gas reserves that are included in  the
discounted  present  value of the reserves do not  require  judgment.   The
ceiling calculation dictates that prices and costs in effect as of the last
day  of  the  period are generally held constant indefinitely. Because  the
ceiling  calculation dictates that prices in effect as of the last  day  of
the  applicable quarter are held constant indefinitely, the resulting value
is  not indicative of the true fair value of the reserves.  Oil and natural
gas  prices have historically been cyclical and, on any particular  day  at
the  end of a quarter, can be either substantially higher or lower than the
Partnership's  long-term price forecast that is a barometer for  true  fair
value.

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.

Results of Operations

A.  General Comparison of the Years Ended December 31, 2001 and 2000

The  following  table  provides certain information  regarding  performance
factors for the years ended December 31, 2001 and 2000:

                                                  Year Ended     Percentage
                                                 December 31,     Increase
                                                2001      2000   (Decrease)
                                                ----      ----   ---------
Average price per barrel of oil            $   22.23    28.31    (21%)
Average price per mcf of gas               $    3.90     3.96     (2%)
Oil production in barrels                      4,000    4,310     (7%)
Gas production in mcf                         37,300   45,900    (19%)
Gross oil and gas revenue                  $ 234,272  304,011    (23%)

Limited partner distributions              $ 128,291   94,617      36%
Per unit distribution to limited partners  $   45.48    33.54      36%
Number of limited partner units                2,821    2,821

Revenues

The  Partnership's oil and gas revenues decreased to $234,272 from $304,011
for the years ended December 31, 2001 and 2000, respectively, a decrease of
23%.   The  principal factors affecting the comparison of the  years  ended
December 31, 2001 and 2000 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the year ended December 31, 2001 as compared  to  the
    year ended December 31, 2000 by 21%, or $6.08 per barrel, resulting  in
    a decrease of approximately $24,300 in revenues.  Oil sales represented
    38%  of total oil and gas sales during the year ended December 31, 2001
    as compared to 40% during the year ended December 31, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    decreased during the same period by 2%, or $.06 per mcf, resulting in a
    decrease of approximately $2,200 in revenues.

    The  total  decrease in revenues due to the change in  prices  received
    from oil and gas production is approximately $26,500.  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 310 barrels or  7%  during  the
    year ended December 31, 2001 as compared to the year ended December 31,
    2000, resulting in a decrease of approximately $8,800 in revenues.

    Gas production decreased approximately 8,600 mcf or 19% during the same
    period, resulting in a decrease of approximately $34,100 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $42,900.  The decrease in gas production is  due  to  one
    lease having a sharp natural decline.

Costs and Expenses

Total  costs and expenses increased to $205,951 from $141,514 for the years
ended  December 31, 2001 and 2000, respectively, an increase of  46%.   The
increase is the result of higher general and administrative expense,  lease
operating costs and depletion expense.

1.    Lease  operating  costs  and production taxes  were  25%  higher,  or
   approximately $27,200 more during the year ended December  31,  2001  as
   compared  to the year ended December 31, 2000.  Lease operating  expense
   increased due to repairs and maintenance, such as pulling expense on two
   leases.

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 increased  7%
    or  approximately  $1,200 during the year ended December  31,  2001  as
    compared to the year ended December 31, 2000.

3.  Depletion expense increased to $51,000 for the year ended December  31,
    2001  from  $15,000  for the same period in 2000.  This  represents  an
    increase  of 240%.  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.

    The  major  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, 2002 as compared
    to  2001,  and  the decrease in oil and gas revenues  received  by  the
    Partnership  during  2001 as compared to 2000.  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  $24,000  as  of
    December 31, 2000.





Results of Operations

B.  General Comparison of the Years Ended December 31, 2000 and 1999

The  following  table  provides certain information  regarding  performance
factors for the years ended December 31, 2000 and 1999:

                                                  Year Ended     Percentage
                                                 December 31,     Increase
                                                2000      1999   (Decrease)
                                                ----      ----   ---------

Average price per barrel of oil            $   28.31    16.55      71%
Average price per mcf of gas               $    3.96     2.26      75%
Oil production in barrels                      4,310    5,240    (18%)
Gas production in mcf                         45,900   55,150    (17%)
Gross oil and gas revenue                  $ 304,011  211,240      44%
Net oil and gas revenue                    $ 193,525  101,088      91%
Partnership distributions                  $ 105,130  109,407     (4%)
Limited partner distributions              $  94,617  100,907     (6%)
Per unit distribution to limited partners  $   33.54    35.77     (6%)
Number of limited partner units                2,821    2,821

Revenues

The  Partnership's oil and gas revenues increased to $304,011 from $211,240
for  the  years ended December 31, 2000 and 1999, respectively, an increase
of  44%.  The principal factors affecting the comparison of the years ended
December 31, 2000 and 1999 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the year ended December 31, 2000 as compared  to  the
    year ended December 31, 1999 by 71%, or $11.76 per barrel, resulting in
    an   increase  of  approximately  $61,600  in  revenues.    Oil   sales
    represented  40%  of  total oil and gas sales  during  the  year  ended
    December 31, 2000 as compared to 41% during the year ended December 31,
    1999.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 75%, or $1.70 per mcf, resulting in
    an increase of approximately $93,800 in revenues.

    The  total  increase in revenues due to the change in  prices  received
    from  oil  and  gas production is approximately $155,400.   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 930 barrels or 18%  during  the
    year ended December 31, 2000 as compared to the year ended December 31,
    1999, resulting in a decrease of approximately $26,300 in revenues.

    Gas production decreased approximately 9,250 mcf or 17% during the same
    period, resulting in a decrease of approximately $36,600 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $62,900.

Costs and Expenses

Total  costs and expenses decreased to $141,514 from $160,312 for the years
ended  December 31, 2000 and 1999, respectively, a decrease  of  12%.   The
decrease  is  the  result of lower general and administrative  expense  and
depletion  expense,  partially offset by an  increase  in  lease  operating
costs.

2.    Lease  operating costs and production taxes were less than 1% higher,
   or  approximately $300 more during the year ended December 31,  2000  as
   compared to the year ended December 31, 1999.

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 16%
    or  approximately  $3,100 during the year ended December  31,  2000  as
    compared to the year ended December 31, 1999.

3.  Depletion expense decreased to $15,000 for the year ended December  31,
    2000  from  $31,000  for the same period in 1999.   This  represents  a
    decrease  of 52%.  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.

    The  major  factor  to  the decrease 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, 2001 as compared
    to  2000.   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  $2,000  as  of
    December 31, 1999.





C.  Revenue and Distribution Comparison

Partnership income for the years ended December 31, 2001, 2000 and 1999 was
$29,292,  $163,740  and $51,963, respectively.  Excluding  the  effects  of
depreciation,  depletion  and amortization,  net  income  would  have  been
$80,292  in  2001,  $178,740 in 2000 and $82,963 in 1999.  Correspondingly,
Partnership distributions for the years ended December 31, 2001,  2000  and
1999 were $142,545, $105,130 and $109,407, respectively.  These differences
are  indicative  of  the  changes in oil and  gas  prices,  production  and
property sales.

The  sources  for  the  2001 distributions of $142,545  were  oil  and  gas
operations  of  approximately  $138,400 and  the  change  in  oil  and  gas
properties of approximately $(4,300), with the balance from available  cash
on  hand  at  the  beginning  of the period.   The  sources  for  the  2000
distributions  of  $105,130  were oil and gas operations  of  approximately
$148,600  and  the  change  in  oil  and gas  properties  of  approximately
$(32,200),  resulting  in  excess  cash  for  contingencies  or  subsequent
distributions. The sources for the 1999 distributions of $109,407 were  oil
and  gas operations of approximately $85,100 and the change in oil and  gas
properties of approximately $(234), with the balance from available cash on
hand at the beginning of the period.

Total  distributions during the year ended December 31, 2001 were  $142,545
of  which  $128,291 was distributed to the limited partners and $14,254  to
the general partners.  The per unit distribution to limited partners during
the  same  period was $45.48.  Total distributions during  the  year  ended
December  31,  2000 were $105,130 of which $94,617 was distributed  to  the
limited  partners  and  $10,513  to the general  partners.   The  per  unit
distribution to limited partners during the same period was $33.54.   Total
distributions  during  the year ended December 31, 1999  were  $109,407  of
which  $100,907 was distributed to the limited partners and $8,500  to  the
general partners.  The per unit distribution to limited partners during the
same period was $35.77.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $1,234,870  have been made to the partners.  As of December  31,  2001,
$1,124,553 or $398.64 per limited partner unit, has been distributed to the
limited partners, representing a 80% return of the capital contributed.



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 $138,400  in
2001  compared to $148,600 in 2000 and approximately $85,100 in 1999.   The
primary  source  of  the  2001  cash flow  from  operating  activities  was
profitable operations.

Cash  flows used in investing activities were approximately $4,300 in  2001
compared  to $32,200 in 2000 and approximately $200 in 1999.  The principal
use of the 2001 cash flow from investing activities was the addition of oil
and gas properties.

Cash flows used in financing activities were approximately $142,500 in 2001
compared to $105,100 in 2000 and approximately $109,400 in 1999.  The  only
use in financing activities was the distributions to partners.

As  of  December  31,  2001, the Partnership had approximately  $10,400  in
working  capital.   The  Managing  General Partner  believes  the  revenues
generated from operations are adequate to meet the operating needs  of  the
Partnership.

Liquidity - Managing General Partner

The  Managing General Partner has a highly leveraged capital structure with
$50.0  million and $123.7 million of principal due in August  of  2003  and
October  of  2004, respectively.  The Managing General Partner  will  incur
approximately  $17.6  million in interest payments  in  2002  on  its  debt
obligations. Due to the depressed commodity prices experienced  during  the
last  quarter  of  2001,  the  Managing  General  Partner  is  experiencing
difficulty  in generating sufficient cash flow to meet its obligations  and
sustain its operations.  The Managing General Partner is currently  in  the
process  of  renegotiating the terms of its various  obligations  with  its
creditors  and/or  attempting  to seek new  lenders  or  equity  investors.
Additionally,  the  Managing General Partner would  consider  disposing  of
certain assets in order to meet its obligations.

There  can  be  no  assurance  that  the Managing  General  Partner's  debt
restructuring efforts will be successful or that the lenders will agree  to
a   course   of  action  consistent  with  the  Managing  General  Partners
requirements  in restructuring the obligations.  Even if such agreement  is
reached,  it  may  require approval of additional  lenders,  which  is  not
assured.   Furthermore, there can be no assurance that the sales of  assets
can  be  successfully  accomplished on terms  acceptable  to  the  Managing
General   Partner.   Under  current  circumstances,  the  Managing  General
Partner's  ability to continue as a going concern depends upon its  ability
to  (1)  successfully  restructure  its obligations  or  obtain  additional
financing  as  may  be  required, (2) maintain  compliance  with  all  debt
covenants, (3) generate sufficient cash flow to meet its obligations  on  a
timely  basis, and (4) achieve satisfactory levels of future earnings.   If
the  Managing  General Partner is unsuccessful in its efforts,  it  may  be
unable to meet its obligations making it necessary to undertake such  other
actions  as  may  be  appropriate  to  preserve  asset  values.   Upon  the
occurrence of any event of dissolution by the Managing General Partner, the
holders  of  a  majority of limited partnership interests may,  by  written
agreement,  elect  to  continue the business  of  the  Partnership  in  the
Partnership's   name,  with  Partnership  property,  in   a   reconstituted
partnership under the terms of the partnership agreement and to designate a
successor Managing General Partner.



Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No.133, "Accounting
for Derivative Instruments and Hedging Activities."  SFAS No. 133, as
amended by SFAS No. 138, establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded
in other contracts and for hedging activities.  Assessment by the Managing
General Partner revealed this pronouncement to have no impact on the
partnerships.

The FASB has issued Statement No. 143 "Accounting for Asset Retirement
Obligations" which establishes requirements for the accounting of removal-
type costs associated with asset retirements.  The standard is effective
for fiscal years beginning after June 15, 2002, with earlier application
encouraged.  The Managing General Partner is currently assessing the impact
on the partnerships financial statements.

On  October 3, 2001, the FASB issued Statements No. 144 "Accounting for the
Impairment   or   Disposal  of  Long-Lived  Assets."   This   pronouncement
supercedes FAS 121 "Accounting for the Impairment of Long-Lived Assets  and
for  Long-Lived  Assets to Be Disposed" and eliminates the  requirement  of
Statement  121 to allocate goodwill to long-lived assets to be  tested  for
impairment.   The provisions of this statement are effective for  financial
statements issued for fiscal years beginning after December 15,  2001,  and
interim periods within those fiscal years.  The Managing General Partner is
currently assessing the impact to the partnerships financial statements.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

instruments.

                        INDEPENDENT AUDITORS REPORT

The Partners
Southwest Oil & Gas Income Fund XI-A, L.P.
 (A Delaware Limited Partnership):


We  have  audited the accompanying balance sheets of Southwest  Oil  &  Gas
Income  Fund  XI-A, L.P. (the "Partnership") as of December  31,  2001  and
2000, and the related statements of operations, changes in partners' equity
and  cash  flows  for  each  of the years in the three  year  period  ended
December  31,  2001.  These financial statements are the responsibility  of
the  Partnership's management.  Our responsibility is to express an opinion
on these financial statements based on our audits.

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

In  our opinion, the financial statements referred to above present fairly,
in  all  material respects, the financial position of Southwest Oil  &  Gas
Income Fund XI-A, L.P. as of December 31, 2001 and 2000 and the results  of
its  operations and its cash flows for each of the years in the three  year
period  ended  December  31, 2001 in conformity with accounting  principles
generally accepted in the United States of America.

                      Notes to Financial Statements

1.   Organization
     Southwest  Oil  & Gas 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:

          (1)   H.H.  Wommack,  III,  President  of  the  Managing  General
          Partner, is an additional general partner in the Partnership  and
          has  a  one percent interest in the Partnership.  Mr. Wommack  is
          the  majority  stockholder of the Managing General Partner  whose
          continued  involvement in Partnership management is important  to
          its  operations.  Mr. Wommack, as a general partner, shares  also
          in Partnership liabilities.

          (2)   Organization and Offering Expenses (including all  cost  of
          selling  and  organizing the offering) include a payment  by  the
          Partnership of an amount equal to three percent (3%)  of  Capital
          Contributions   for   reimbursement  of   such   expenses.    All
          Organization Costs (which excludes sales commissions and fees) in
          excess  of  three  percent  (3%) of  Capital  Contributions  with
          respect to the Partnership will be allocated to and paid  by  the
          Managing General Partner.

          (3)   Administrative  Costs will be paid from  the  Partnership's
          revenues;  however; Administrative Costs in the Partnership  year
          in  excess of two percent (2%) of Capital Contributions shall  be
          allocated to and paid by the Managing General Partner.

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.

                      Notes to Financial Statements

2.   Summary of Significant Accounting Policies - continued

     Oil and Gas Properties - continued
     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, 2001, 2000  and  1999,
     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. The Partnerships  depletion
     calculation and full-cost ceiling test for oil and gas properties uses
     oil and gas reserves estimates, which are inherently imprecise. Actual
     results could differ from those estimates.

     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, 2001, 2000 and 1999
     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.

                      Notes to Financial Statements

2.   Summary of Significant Accounting Policies - continued

     Income Taxes - continued
     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,  2001 is $6,558, more than that shown on the accompanying  Balance
     Sheet  in  accordance  with generally accepted accounting  principles.
     The  Partnership's  tax  basis in its net oil and  gas  properties  at
     December 31, 2000 is $23,203, less than that shown on the accompanying
     Balance   Sheet  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.

     Number of Limited Partner Units
     As  of  December  31,  2001, 2000 and 1999 there  were  2,821  limited
     partner units outstanding held by 120, 121 and 120 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.

     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.

     Recent Accounting Pronouncements
     In June 1998, the Financial Accounting Standards Board ("FASB") issued
     Statement   of   Financial  Accounting  Standards   ("SFAS")   No.133,
     "Accounting for Derivative Instruments and Hedging Activities."   SFAS
     No.  133,  as  amended  by  SFAS No. 138, establishes  accounting  and
     reporting  standards  for  derivative instruments,  including  certain
     derivative  instruments embedded in other contracts  and  for  hedging
     activities.  Assessment by the Managing General Partner revealed  this
     pronouncement to have no impact on the partnerships.

     The FASB has issued Statement No. 143 "Accounting for Asset Retirement
     Obligations"  which  establishes requirements for  the  accounting  of
     removal-type costs associated with asset retirements.  The standard is
     effective for fiscal years beginning after June 15, 2002, with earlier
     application  encouraged.  The Managing General  Partner  is  currently
     assessing the impact on the partnerships financial statements.

     On October 3, 2001, the FASB issued Statements No. 144 "Accounting for
     the  Impairment or Disposal of Long-Lived Assets."  This pronouncement
     supercedes FAS 121 "Accounting for the Impairment of Long-Lived Assets
     and   for  Long-Lived  Assets  to  Be  Disposed"  and  eliminates  the
     requirement of Statement 121 to allocate goodwill to long-lived assets
     to  be  tested  for impairment.  The provisions of this statement  are
     effective  for financial statements issued for fiscal years  beginning
     after  December  15,  2001, and interim periods  within  those  fiscal
     years.  The Managing General Partner is currently assessing the impact
     to the partnerships financial statements.

                      Notes to Financial Statements

3.   Liquidity - Managing General Partner
     The  Managing General Partner has a highly leveraged capital structure
     with  $50.0 million and $123.7 million of principal due in  August  of
     2003  and October of 2004, respectively.  The Managing General Partner
     will incur approximately $17.6 million in interest payments in 2002 on
     its   debt   obligations.  Due  to  the  depressed  commodity   prices
     experienced  during  the last quarter of 2001,  the  Managing  General
     Partner is experiencing difficulty in generating sufficient cash  flow
     to  meet  its  obligations and sustain its operations.   The  Managing
     General Partner is currently in the process of renegotiating the terms
     of  its  various obligations with its creditors and/or  attempting  to
     seek  new  lenders  or equity investors.  Additionally,  the  Managing
     General Partner would consider disposing of certain assets in order to
     meet its obligations.

     There  can  be  no assurance that the Managing General Partner's  debt
     restructuring  efforts  will be successful or that  the  lenders  will
     agree  to  a  course  of action consistent with the  Managing  General
     Partners requirements in restructuring the obligations.  Even if  such
     agreement  is reached, it may require approval of additional  lenders,
     which is not assured.  Furthermore, there can be no assurance that the
     sales  of  assets can be successfully accomplished on terms acceptable
     to  the  Managing  General Partner.  Under current circumstances,  the
     Managing  General  Partner's ability to continue as  a  going  concern
     depends   upon  its  ability  to  (1)  successfully  restructure   its
     obligations  or  obtain additional financing as may be  required,  (2)
     maintain  compliance with all debt covenants, (3) generate  sufficient
     cash  flow to meet its obligations on a timely basis, and (4)  achieve
     satisfactory  levels  of  future earnings.  If  the  Managing  General
     Partner  is unsuccessful in its efforts, it may be unable to meet  its
     obligations making it necessary to undertake such other actions as may
     be  appropriate to preserve asset values.  Upon the occurrence of  any
     event of dissolution by the Managing General Partner, the holders of a
     majority  of limited partnership interests may, by written  agreement,
     elect to continue the business of the Partnership in the Partnership's
     name,  with Partnership property, in a reconstituted partnership under
     the  terms  of the partnership agreement and to designate a  successor
     Managing General Partner.

4.   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.

     As  of December 31, 2001, 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 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  $24,000,
     $24,800  and $26,600 for the years ended December 31, 2001,  2000  and
     1999.   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
     $7,400,  $500 and $2,800 for the years ended December 31, 2001,  2000,
     respectively.

     Southwest  Royalties,  Inc., the Managing General  Partner,  was  paid
     $12,000,  $12,000 and $14,000 for the years ended December  31,  2001,
     2000  and  1999,  as an administrative fee, for indirect  general  and
     administrative overhead expenses.

     (Payable)  Receivables  (to)  from  Southwest  Royalties,  Inc.,   the
     Managing  General Partner, of approximately $(2,700) and  $55,400  are
     from  oil  and  gas  production,  net of  lease  operating  costs  and
     production taxes, as of December 2001 and 2000, 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.  There were no legal services provided for the  year
     ended December 31, 2001, 2000 and 1999.

6.   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.   Five
     purchasers  accounted for 85% of the Partnership's total oil  and  gas
     production during 2001:  Sid Richardson Energy Services for 26%,  Duke
     Energy  Field  Services  for 17%, Phillips 66  Company  for  17%,  Sap
     Acquisition Corporation for 15%, and Navajo Refining Company, Inc. for
     10%.  Four purchasers accounted for 76% of the Partnership's total oil
     and  gas production during 2000:  Sid Richardson Gasoline Co. for 21%,
     Phillips 66 Company for 33%, Navajo Refining Company Inc. for 11%  and
     Southwestern Energy Production Co. for 11%.  Four purchasers accounted
     for 75% of the Partnership's total oil and gas production during 1999:
     Phillips  66 Company for 30%, Southwestern Energy Production  Co.  for
     19%, Sid Richardson Gasoline Co. for 16% and Navajo Refining Co., Inc.
     for  10%.   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.

7.   Estimated Oil and Gas Reserves (unaudited) - continued
     *Ryder  Scott  Petroleum Engineers prepared the  reserve  and  present
     value data for the Partnership's existing properties as of January  1,
     2002.   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.

     Oil  price  adjustments  were made in the  individual  evaluations  to
     reflect  oil quality, gathering and transportation costs. The  results
     of  the  reserve report as of January 1, 2002 are an average price  of
     $17.14 per barrel.

     Gas  price  adjustments  were made in the  individual  evaluations  to
     reflect  BTU  content,  gathering and  transportation  costs  and  gas
     processing  and shrinkage.  The results of the reserve  report  as  of
     January 1, 2002 are an average price of $2.03 per Mcf.

     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
     farmout  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 farmout,
     or receives cash.

Key Employees

Jon  P. Tate, Vice President, Land and Assistant Secretary, age 44, assumed
his  responsibilities with the Managing General Partner in 1989.  Prior  to
joining  the  Managing  General Partner, Mr.  Tate  was  employed  by  C.F.
Lawrence  & Associates, Inc., an independent oil and gas company,  as  Land
Manager from 1981 through 1989.  Mr. Tate is a member of the Permian  Basin
Landman's  Association and American Association of Petroleum Landmen.   Mr.
Tate received his B.B.S. degree from Hardin-Simmons University.

R.  Douglas  Keathley,  Vice President, Operations,  age  46,  assumed  his
responsibilities with the Managing General Partner as a Production Engineer
in  October,  1992.   Prior to joining the Managing  General  Partner,  Mr.
Keathley  was  employed for four (4) years by ARCO Oil  &  Gas  Company  as
senior  drilling  engineer working in all phases of well production  (1988-
1992),  eight  (8)  years by Reading & Bates Petroleum  Company  as  senior
petroleum  engineer responsible for drilling (1980-1988) and two (2)  years
by  Tenneco Oil Company as drilling engineer responsible for all phases  of
drilling   (1978-1980).   Mr.  Keathley  received  his  B.S.  in  Petroleum
Engineering in 1977 from the University of Oklahoma.

In certain instances, the Managing General Partner will engage professional
petroleum   consultants   and  other  independent  contractors,   including
engineers   and   geologists  in  connection  with  property  acquisitions,
geological  and  geophysical  analysis,  and  reservoir  engineering.   The
Managing  General Partner believes that, in addition to its own  "in-house"
staff,  the 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  Partner
received  $12,000, $12,000 and $14,000 during 2001, 2000  and  1999  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  in  the
Partnership  as a general partner.  Through prior purchases,  the  Managing
General  Partner  also  owns 40.0 limited partner units,  or  1.4%  limited
partner  interest.  The Managing General Partner total percentage  interest
ownership in the Partnership is 10.3%.

No  officer  or  director  of  the  Managing  Partner  owns  Units  in  the
Partnership.  H.H. Wommack, III, as the individual general partner  of  the
Partnership,  owns a one percent interest in the Partnership as  a  general
partner.   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 2001, the Managing General Partner received $12,000 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 $24,000 for administrative  overhead
attributable to operating such properties during 2001.

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 $7,400 for the year ended
December 31, 2001.

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