conditions, i.e., prices and costs as of the date the estimate is made.

     Proved  undeveloped  reserves.  Reserves  that  are  expected  to   be
recovered from new wells on undrilled acreage, or from existing wells where
a relatively major expenditure is required for recompletion.

     Reservoir.  A porous and permeable underground formation containing  a
natural  accumulation  of  producible  oil  or  gas  that  is  confined  by
impermeable  rock  or water barriers and is individual  and  separate  from

                                  Part I

Item 1.   Business

General
Southwest   Oil  &  Gas  Income  Fund  X-C,  L.P.  (the  "Partnership"   or
"Registrant") was organized as a Delaware limited partnership on  September
20,  1991.  The offering of limited partnership interests began October  1,
1991 as part of a shelf offering registered under the name Southwest Oil  &
Gas   1990-91  Income  Program.   Minimum  capital  requirements  for   the
Partnership were met on January 13, 1992 and concluded April 30, 1992.  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  81  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, Chairman, Director, President and Chief Executive Officer  of
the  Managing General Partner, is also a general partner.  The  Partnership
has no employees.

Introductory Note - Statement of Financial Accounting Standard No. 143
The  Partnership implemented SFAS No. 143 effective January  1,  2003  (See
Note 3 to the Partnership's financial statements).

Introductory Note - Depletion Method
During  2002, the Partnership changed its method of providing for depletion
from  the  units-of-revenue  method to the  units-of-production  method  as
described in Note 4 to the Partnership's financial statements.  This change
in  depletion  method was applied as a cumulative effect  of  a  change  in
accounting principle effective as of January 1, 2002.

Principal Products, Marketing and Distribution
The  Partnership has acquired and holds 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.


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

            Oil       Gas
            ----      ----
  2003      88%       12%
  2002      84%       16%
  2001      72%       28%

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

Seasonality of Business
Although  the  demand for natural gas can be effected by seasonality,  with
higher  demand  in the colder winter months and in very hot summer  months,
the  Partnership has not experienced material price and volume changes  due
to  seasonality  and 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.

Customer Dependence
The  Managing  General  Partner intends that no  material  portion  of  the
Partnership's business is dependent on a single purchaser, or  a  very  few
purchasers, where the loss of one would have a material adverse  impact  on
the  Partnership.   Two purchasers accounted for 82% of  the  Partnership's
total oil and gas production during 2003: Teppco Crude Oil LLC for 72%  and
Plains  Marketing  LP  for  10%.   Contracts  for  2003  with  these  major
purchasers  cover  month-to-month contracts.  Prices  received  from  these
major  purchasers ranged from a low of $26.57 per Bbl to a high  of  $29.75
per  Bbl.  Two purchasers accounted for 80% of the Partnership's total  oil
and  gas  production during 2002: Teppco Crude Oil LLC for 68%  and  Plains
Marketing LP for 12%.  Contracts for 2002 with these major purchasers cover
month-to-month  contracts.   Prices received from  these  major  purchasers
ranged  from  a low of $20.34 per Bbl to a high of $22.98 per  Bbl.   Three
purchasers  accounted  for  85%  of the Partnership's  total  oil  and  gas
production during 2001: Teppco Crude Oil LLC for 60%, George L Mcleod  Inc.
for  14%  and Plains Marketing LP for 11%.  Contracts for 2001  with  these
major  purchasers  cover month-to-month contracts.   Prices  received  from
these  major purchasers ranged from a low of $23.18 per Bbl to  a  high  of
$26.75 per Bbl and $5.76 per mcf.  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,  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 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.   The regulatory burden on the oil  and  gas  industry
increases  the  Partnership's  cost of doing business,  and,  consequently,
affects its profitability.

<PAGE>
Regulation  of  Sales  and Transportation of Natural  Gas.   Our  sales  of
natural   gas  are  affected  by  the  availability,  terms  and  cost   of
transportation.  The price and terms for access to pipeline  transportation
are  subject  to  extensive  regulation. In  recent  years,  the  FERC  has
undertaken  various initiatives to increase competition within the  natural
gas industry. As a result of initiatives like FERC Order No. 636, issued in
April  1992, the interstate natural gas transportation and marketing system
has   been  substantially  restructured  to  remove  various  barriers  and
practices  that  historically  limited non-pipeline  natural  gas  sellers,
including  producers, from effectively competing with interstate  pipelines
for  sales  to  local  distribution  companies  and  large  industrial  and
commercial  customers. The most significant provisions  of  Order  No.  636
require   that   interstate  pipelines  provide  firm   and   interruptible
transportation  service  on an open access basis  that  is  equal  for  all
natural  gas supplies. In many instances, the results of Order No. 636  and
related  initiatives  have been to substantially reduce  or  eliminate  the
interstate  pipelines' traditional role as wholesalers of  natural  gas  in
favor  of  providing  only storage and transportation services.  While  the
United  States  Court  of  Appeals upheld most of Order  No.  636,  certain
related  FERC  orders,  including  the  individual  pipeline  restructuring
proceedings,  are still subject to judicial review and may be  reversed  or
remanded in whole or in part. While the outcome of these proceedings cannot
be  predicted  with certainty, we do not believe that we will  be  affected
materially differently than its competitors.

The FERC has also announced several important transportation-related policy
statements and proposed rule changes, including a statement of policy and a
request  for  comments concerning alternatives to its traditional  cost-of-
service rate making methodology to establish the rates interstate pipelines
may  charge  for their services. A number of pipelines have  obtained  FERC
authorization  to  charge  negotiated rates as  one  such  alternative.  In
February  1997, the FERC announced a broad inquiry into issues  facing  the
natural  gas  industry to assist the FERC in establishing regulatory  goals
and  priorities in the post-Order No. 636 environment. Similarly, the Texas
Railroad Commission has been reviewing changes to its regulations governing
transportation and gathering services provided by intrastate pipelines  and
gatherers.  While the changes being considered by these federal  and  state
regulators  would affect us only indirectly, they are intended  to  further
enhance  competition in natural gas markets. We cannot predict what further
action the FERC or state regulators will take on these matters, however, we
do  not  believe  that it will be affected by any action  taken  materially
differently than other natural gas producers with which it competes.

Additional  proposals  and proceedings that might affect  the  natural  gas
industry are pending before Congress, the FERC, state commissions  and  the
courts.  The  natural  gas  industry historically  has  been  very  heavily
regulated;  therefore,  there  is  no assurance  that  the  less  stringent
regulatory  approach  recently  pursued  by  the  FERC  and  Congress  will
continue.

Oil Price Controls and Transportation Rates. Sales of crude oil, condensate
and  gas  liquids by us are not currently regulated and are made at  market
prices.  The  price  we  receive from the sale of  these  products  may  be
affected by the cost of transporting the products to market.

Environmental  and  Health Controls.  Extensive federal,  state  and  local
regulatory and common laws regulating the discharge of materials  into  the
environment  or  otherwise relating to the protection  of  the  environment
affect   our   oil  and  natural  gas  operations.  Numerous   governmental
departments issue rules and regulations to implement and enforce such laws,
which  are  often  difficult  and costly to comply  with  and  which  carry
substantial  civil and even criminal penalties for failure to comply.  Some
laws, rules and regulations relating to protection of the environment  may,
in   certain  circumstances,  impose  strict  liability  for  environmental
contamination,  rendering  a person liable for  environmental  damages  and
cleanup  costs without regard to negligence or fault on the  part  of  such
person. Other laws, rules and regulations may restrict the rate of oil  and
natural  gas production below the rate that would otherwise exist  or  even
prohibit  exploration  and production activities  in  sensitive  areas.  In
addition,  state  laws often require various forms of  remedial  action  to
prevent  pollution,  such  as  closure of inactive  pits  and  plugging  of
abandoned wells. The regulatory burden on the oil and natural gas  industry
increases  our  cost  of  doing  business  and  consequently  affects   our
profitability.  We  believe  that  we are in  substantial  compliance  with
current  applicable environmental laws and regulations and  that  continued
compliance  with  existing requirements will not have  a  material  adverse
impact on our operations. However, environmental laws and regulations  have
been subject to frequent changes over the years, and the imposition of more
stringent  requirements  could  have a material  adverse  effect  upon  our
capital  expenditures,  earnings  or competitive  position.   Additionally,
given  the  intense litigation environment in the United States,  a  threat
exists  of  lawsuits  alleging personal injury  and  property  damage  from
environmental  contamination  alleged  to  be  created  by  us  or  related
entities.   Potential  liability  in such lawsuits  can  include  not  only
compensatory, but substantial punitive damages as well.  We are  not  aware
of any such suits currently pending or threatened.

<PAGE>
The  Comprehensive Environmental Response, Compensation and  Liability  Act
("CERCLA"),  also known as the "Superfund" law, imposes liability,  without
regard  to  fault on certain classes of persons that are considered  to  be
responsible   for  the  release  of  a  "hazardous  substance"   into   the
environment. These persons include the current or former owner or  operator
of the disposal site or sites where the release occurred and companies that
disposed or arranged for the disposal of hazardous substances. Under CERCLA
such persons may be subject to joint and several liability for the costs of
investigating and cleaning up hazardous substances that have been  released
into the environment, for damages to natural resources and for the costs of
certain  health  studies.  In  addition,  companies  that  incur  liability
frequently also confront third party claims because it is not uncommon  for
neighboring landowners and other third parties to file claims for  personal
injury  and  property  damage allegedly caused by hazardous  substances  or
other  pollutants  released  into the environment  from  a  polluted  site.
Potential  liability also exists under CERCLA for natural resource  damage.
A  Natural  Resource Damage Action (NRDA) could result in  liability  being
assessed for restoration to natural resources.

The  Federal Oil Pollution Act of 1990 ("OPA") regulates the release of oil
into  water  or  other areas designated by the statute.   A  release  could
result  in  our  being  held responsible for the cost  of  remediating  the
release, OPA specified damages and natural resource damages.  The extent of
such liability could be extensive.   A release of oil in harmful quantities
or other materials into water or other specified areas could also result in
our  being held responsible under the Clean Water Act ("CWA") for the costs
of remediation, and any civil and criminal fines and penalties.

The   Federal  Solid  Waste  Disposal  Act,  as  amended  by  the  Resource
Conservation  and Recovery Act of 1976 ("RCRA"), regulates the  generation,
transportation,  storage, treatment and disposal  of  solid  and  hazardous
wastes and can require cleanup of abandoned hazardous waste disposal  sites
as  well  as  waste management areas operating facilities.  RCRA  currently
excludes drilling fluids, produced waters and other wastes associated  with
the  exploration,  development or production of oil and  natural  gas  from
regulation  as  "hazardous waste." Disposal of such non-hazardous  oil  and
natural  gas  exploration, development and production  wastes  usually  are
regulated  by state law. Other wastes handled at exploration and production
sites  or used in the course of providing well services may not fall within
this  exclusion.  Moreover,  stricter  standards  for  waste  handling  and
disposal may be imposed on the oil and natural gas industry in the  future.
From time to time legislation is proposed in Congress that would revoke  or
alter  the  current  exclusion of exploration, development  and  production
wastes  from  the RCRA definition of "hazardous wastes" thereby potentially
subjecting  such  wastes to more stringent handling, disposal  and  cleanup
requirements. If such legislation were enacted it could have a  significant
impact  on the operating costs of Southwest and Sierra, as well as the  oil
and natural gas industry and well servicing industry in general. The impact
of  future  revisions  to  environmental laws  and  regulations  cannot  be
predicted.  In addition, if our operations were to trigger regulation under
RCRA,  we could be required to satisfy certain financial criteria to ensure
financial  ability  to comply with RCRA regulations.   Proof  of  financial
responsibility  could  be required in the form of  dedicated  trust  funds,
irrevocable letters of credit, posting of bonds, etc.

The Federal Clean Water Act ("CWA") contains provisions that may result  in
the imposition of certain water pollution control requirements with respect
to water releases from our operations.  We may be required to incur certain
capital  expenditures in the next several years for water pollution control
equipment  in connection with obtaining and maintaining National  Pollutant
Discharge  Elimination Systems ("NPDES") permits.  However, we believe  our
operations  will  not  be  materially  adversely  affected  by   any   such
requirements,  and  the  requirements are  not  expected  to  be  any  more
burdensome to us than to other similarly situated companies involved in oil
and  natural  gas exploration and production activities or  well  surfacing
activities.

Our  operations are also subject to the federal Clean Air Act  ("CAA")  and
comparable state and local requirements. Amendments to the CAA were adopted
in 1990 and contain provisions that may result in the gradual imposition of
certain  pollution control requirements with respect to air emissions  from
our operations. We may be required to incur certain capital expenditures in
the  next  several years for air pollution control equipment in  connection
with  obtaining  and maintaining operating permits and  approvals  for  air
emissions.  However,  we  believe our operations  will  not  be  materially
adversely affected by any such requirements, and the requirements  are  not
expected  to be any more burdensome to us than to other similarly  situated
companies  involved  in  oil  and natural gas  exploration  and  production
activities or well servicing activities.

We  maintain  insurance against "sudden and accidental" occurrences,  which
may  cover  some, but not all, of the environmental risks described  above.
Most  significantly,  the insurance we maintain will not  cover  the  risks
described above which occur over a sustained period of time. Further, there
can  be  no assurance that such insurance will continue to be available  to
cover  all  such costs or that such insurance will be available at  premium
levels  that  justify its purchase.  The occurrence of a significant  event
not  fully  insured  or indemnified against could have a  material  adverse
effect on our financial condition and operations.

<PAGE>
Limited   partners  should  be  aware  that  the  assessment  of  liability
associated with environmental liabilities is not always correlated  to  the
value of a particular project.  Accordingly, liability associated with  the
environment under local, state, or federal regulations, particularly  clean
ups  under CERCLA, can exceed the value of our investment in the associated
site.

Regulation  of  Oil  and  Natural  Gas  Exploration  and  Production.   Our
exploration  and  production operations are subject  to  various  types  of
regulation  at  the  federal,  state and local  levels.   Such  regulations
include  requiring  permits and drilling bonds for the drilling  of  wells,
regulating the location of wells, the method of drilling and casing  wells,
and  the  surface  use and restoration of properties upon which  wells  are
drilled.    Many  states  also  have  statutes  or  regulations  addressing
conservation matters, including provisions for the utilization  or  pooling
of  oil  and natural gas properties, the establishment of maximum rates  of
production  from oil and natural gas wells and the regulation  of  spacing,
plugging and abandonment of such wells.  Some state statutes limit the rate
at which oil and natural gas can be produced from our properties.

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,
2003  there  were 81 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, 2003, the Partnership possessed an interest in oil  and
gas  properties located in Escambia and Lamar Counties of Alabama;  Labette
and  Neosho  Counties  of Kansas; Pointe Coupe and Terrebonne  Parishes  of
Louisiana;  Chaves,  Lea Counties of New Mexico; Custer,  Roger  Mills  and
Washita  Counties  of  Oklahoma, and Dickens,  Hemphill,  Live  Oak,  Lynn,
Martin,  Mitchell,  Scurry,  Upton  and Yoakum  Counties  of  Texas.  These
properties consist of various interests in 180 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 except for sale of properties  as  noted
below during 2003, 2002 and 2001.

Two leases were sold for approximately $142,400 during 2003.  One lease was
sold for $7,000 during 2002.  There were no property sales during 2001.

(1)Amounts  represent  proved developed reserves from  currently  producing
zones.

*Ryder Scott Company, L.P. prepared the reserve and present value data  for
the  Partnership's existing properties as of January 1, 2004.  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, 2004 are an average price of $29.48 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, 2004 are  an
average price of $3.83 per Mcf.

<PAGE>
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 2003.

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.

Partnership has reserves, which are classified as proved developed.  All of
the proved reserves are included in the engineering reports, which evaluate
the Partnership's present reserves.

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

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.  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 2003 through the solicitation of proxies or otherwise.

Item 5.   Market  for  the Registrant's Common Equity, Related  Stockholder
          Matters and Issuer Purchases of Equity Securities

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  in
accordance  with the obligations set forth in the partneship agreement,  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  under
the partnership agreement.

base  price  of  $75.35  per unit.  In 2002, the Managing  General  Partner
purchased no limited partner units.  In 2001, 50 limited partner units were
tendered  to  and purchased by the Managing General Partner at  an  average
base  price of $148.04 per unit.  The discretionary repurchases  were  made
based upon the partnership agreement.

Number of Limited Partner Interest Holders
As of December 31, 2003, there were 292 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 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)  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."

During  2003,  distributions  were made totaling  $205,713,  with  $187,065
distributed  to  the limited partners and $18,648 to the general  partners.
For  the  year ended December 31, 2003, distributions of $29.95 per limited
partner unit were made, based upon 6,246 limited partner units outstanding.
During  2002,  distributions  were  made  totaling  $18,405,  with  $16,565
distributed  to  the limited partners and $1,840 to the  general  partners.
For  the  year ended December 31, 2002, distributions of $2.65 per  limited
partner unit were made, based upon 6,246 limited partner units outstanding.
During  2001,  distributions  were made totaling  $361,479,  with  $325,331
distributed  to  the limited partners and $36,148 to the general  partners.
For  the  year ended December 31, 2001, distributions of $52.09 per limited
partner unit were made, based upon 6,246 limited partner units outstanding.

Item 7.   Management's  Discussion and Analysis of Financial Condition  and
          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 decline in later years based  on  these
factors.

Based on current conditions, management anticipates performing no workovers
during  2004  to  enhance  production.  The partnership  will  most  likely
continue  to  experience  the  historical  production  decline,  which  has
approximated  10%  per  year.   Accordingly,  if  commodity  prices  remain
unchanged,  the  Partnership  expects future earnings  to  decline  due  to
anticipated production declines.

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.

In  2002,  the  Partnership changed methods of accounting for depletion  of
capitalized  costs  from  the  units-of-revenue  method  to  the  units-of-
production method.  The newly adopted accounting principle is preferable in
the  circumstances  because the units-of-production  method  results  in  a
better  matching of the costs of oil and gas production against the related
revenue received in periods of volatile prices for production as have  been
experienced  in  recent  periods.   Additionally,  the  units-of-production
method is the predominant method used by full cost companies in the oil and
gas  industry,  accordingly, the change improves the comparability  of  the
Partnership's financial statements with its peer group.

Revenues

The  Partnership's oil and gas revenues increased to $693,776 from $575,293
for  the  years ended December 31, 2003 and 2002, respectively, an increase
of  21%.  The principal factors affecting the comparison of the years ended
December 31, 2003 and 2002 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the year ended December 31, 2003 as compared  to  the
    year ended December 31, 2002 by 23%, or $5.19 per barrel, resulting  in
    an   increase  of  approximately  $121,400  in  revenues.   Oil   sales
    represented  93%  of  total oil and gas sales  during  the  year  ended
    December 31, 2003 as compared to 91% during the year ended December 31,
    2002.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 27%, or $.69 per mcf, resulting  in
    an increase of approximately $9,900 in revenues.

    The  total  increase in revenues due to the change in  prices  received
    from  oil  and  gas production is approximately $131,300.   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.

<PAGE>
2.  Oil  production  increased approximately 100 barrels or  less  than  1%
    during  the year ended December 31, 2003 as compared to the year  ended
    December 31, 2002, resulting in an increase of approximately $2,200  in
    revenues.

    Gas production decreased approximately 6,300 mcf or 31% during the same
    period, resulting in a decrease of approximately $15,800 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $13,600.  The decrease in gas volumes was the  result  of
    selling two significant leases.

Costs and Expenses

Total  costs and expenses increased to $740,291 from $589,674 for the years
ended  December 31, 2003 and 2002, respectively, an increase of  26%.   The
increase  is  the  result of the addition of accretion expense  and  higher
lease  operating expense and general and administrative expense,  partially
offset by a decrease in depletion expense.

1.    Lease  operating  costs  and production taxes  were  18%  higher,  or
   approximately $91,200 more during the year ended December  31,  2003  as
   compared  to  the year ended December 31, 2002.  The increase  in  lease
   operating costs is the result of well work performed on four leases and the
   increase in production taxes due to an increase in oil and gas commodity
   prices.

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
    13% or approximately $5,500 during the year ended December 31, 2003  as
    compared to the year ended December 31, 2002.  The increase in  general
    and  administrative  expense  is  due to  an  increase  in  independent
    accounting review and audit fees.

3.  Depletion expense decreased to $41,000 for the year ended December  31,
    2003  from  $47,000  for the same period in 2002.   This  represents  a
    decrease  of 13%.  The contributing factor to the decrease in depletion
    expense  is  in relation to the BOE depletion rate for the  year  ended
    December 31, 2003, which was $1.59 applied to 25,800 BOE as compared to
    $1.76 applied to 26,730 BOE for the same period.

Cumulative effect of change in accounting principle - SFAS No. 143
On  January  1,  2003,  the  Partnership  adopted  Statement  of  Financial
Accounting  Standards No. 143, Accounting for Asset Retirement  Obligations
("SFAS  No. 143").  Adoption of SFAS No. 143 is required for all  companies
with fiscal years beginning after June 15, 2002.  The new standard requires
the Partnership to recognize a liability for the present value of all legal
obligations  associated with the retirement of tangible  long-lived  assets
and to capitalize an equal amount as a cost of the asset and depreciate the
additional cost over the estimated useful life of the asset.  On January 1,
2003,  the  Partnership  recorded  additional  costs,  net  of  accumulated
depreciation,  of  approximately  $227,654,  a  long  term   liability   of
approximately  $797,872  and  a  loss of  approximately  $570,218  for  the
cumulative  effect  on depreciation of the additional costs  and  accretion
expense  on the liability related to expected abandonment costs of its  oil
and  natural  gas  producing properties.  At December 31, 2003,  the  asset
retirement  obligation  was $714,041.  The decrease  in  the  balance  from
January  1,  2003  is  due  to property sales, which  decreased  the  asset
retirement obligation by $108,159 and plug and abandonment of oil  and  gas
properties,  which  decreased the asset retirement obligation  by  $35,655,
partially offset by accretion expense of $59,917 and the addition of a well
for  $76.  The pro forma amounts of the asset retirement obligation  as  of
December 31, 2002, 2001 and 2000, were approximately $797,872, $739,149 and
$684,748,  respectively.   The pro forma amounts of  the  asset  retirement
obligation were measured using information, assumptions and interest  rates
as of the adoption date of January 1, 2003.

Revenues

The  Partnership's oil and gas revenues decreased to $575,293 from $648,691
for the years ended December 31, 2002 and 2001, respectively, a decrease of
11%.   The  principal factors affecting the comparison of the  years  ended
December 31, 2002 and 2001 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the year ended December 31, 2002 as compared  to  the
    year  ended December 31, 2001 by 5%, or $1.06 per barrel, resulting  in
    an increase of approximately $24,700 in revenues. Oil sales represented
    91%  of total oil and gas sales during the year ended December 31, 2002
    as compared to 82% during the year ended December 31, 2001.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    decreased during the same period by 29%, or $1.05 per mcf, resulting in
    a decrease of approximately $21,600 in revenues.

    The net total increase in revenues due to the change in prices received
    from  oil and gas production is approximately $3,100.  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>
2.  Oil  production decreased approximately 1,700 barrels or 7% during  the
    year ended December 31, 2002 as compared to the year ended December 31,
    2001, resulting in a decrease of approximately $36,400 in revenues.

    Gas  production  decreased approximately 11,500 mcf or 36%  during  the
    same  period,  resulting  in  a decrease of  approximately  $40,900  in
    revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $77,300.  The decrease in gas production is due primarily
    to  a  well  having mechanical problems during the middle of  2002  and
    another well that was salted up during the first quarter of 2002, which
    has  been  pulled and treated, and is currently producing  at  the  old
    rate.   The decrease in gas production was partially offset by  another
    well coming back online in January of 2002.

Costs and Expenses

Total  costs and expenses decreased to $589,674 from $650,739 for the years
ended  December  31, 2002 and 2001, respectively, a decrease  of  9%.   The
decrease  is  the  result of lower depletion expense  and  lease  operating
expense,  partially  offset  by an increase in general  and  administrative
expense.

2.   Lease operating costs and production taxes were less than 1% lower, or
   approximately  $2,700 less during the year ended December  31,  2002  as
   compared to the year ended December 31, 2001.

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 2%
    or  approximately  $700  during the year ended  December  31,  2002  as
    compared to the year ended December 31, 2001.

3.  Depletion expense decreased to $47,000 for the year ended December  31,
    2002  from  $106,000 for the same period in 2001.   This  represents  a
    decrease  of  56%.   In  the fourth quarter of  2002,  the  Partnership
    changed  methods of accounting for depletion of capitalized costs  from
    the  units-of-revenue  method to the units-of-production  method.   The
    newly  adopted  accounting principle is preferable in the circumstances
    because the units-of-production method results in a better matching  of
    the  costs  of  oil  and  gas production against  the  related  revenue
    received  in  periods of volatile prices for production  as  have  been
    experienced  in  recent periods.  Additionally, the units-of-production
    method is the predominant method used by full cost companies in the oil
    and gas industry, accordingly, the change improves the comparability of
    the Partnership's financial statements with its peer group.  The effect
    of  this  change  in method was to increase 2002 depletion  expense  by
    $22,000  and increase 2002 net income by $106,000.  See Note 4  of  the
    notes to the Partnership's financial statements.

   The  major  factor  in  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, 2003 as compared
   to  2002,  which provided more economically recoverable proved  reserves
   at  January 1, 2003 which caused the depletion rate per equivalent  unit
   produced  to  decline.  Also, as discussed above, the  total  equivalent
   units produced in 2002 declined from 2001.

C.  Revenue and Distribution Comparison

Partnership income (loss) for the years ended December 31, 2003,  2002  and
2001  was  $(563,759),  $139,065 and $125,209,  respectively.   Partnership
distributions  for the years ended December 31, 2003, 2002  and  2001  were
$$205,713,  18,405  and  $361,479,  respectively.   These  differences  are
indicative  of the changes in oil and gas prices, production  and  property
sales.

The  source  for  the  2003  distributions of  $205,713  was  oil  and  gas
operations  of  approximately  $156,600 and  the  change  in  oil  and  gas
properties  of  approximately  $93,200,  resulting  in  excess   cash   for
contingencies  or  subsequent  distributions.   The  source  for  the  2002
distributions  of  $18,405  was  oil and gas  operations  of  approximately
$25,200  and  the  change  in  oil  and  gas  properties  of  approximately
$(21,600), with the balance from available cash on hand at the beginning of
the  period.  The source for the 2001 distributions of $361,479 was oil and
gas  operations  of approximately $331,200 and the change in  oil  and  gas
properties of approximately $(7,200), with the balance from available  cash
on hand at the beginning of the period.

Total  distributions during the year ended December 31, 2003 were  $205,713
of  which  $187,065 was distributed to the limited partners and $18,648  to
the general partners.  The per unit distribution to limited partners during
the  same  period was $29.95.  Total distributions during  the  year  ended
December  31,  2002  were $18,405 of which $16,565 was distributed  to  the
limited  partners  and  $1,840  to  the general  partners.   The  per  unit
distribution  to limited partners during the same period was $2.65.   Total
distributions  during  the year ended December 31, 2001  were  $361,479  of
which  $325,331 was distributed to the limited partners and $36,148 to  the
general partners.  The per unit distribution to limited partners during the
same period was $52.09.

Cumulative  cash distributions of $3,899,919 have been made to the  general
and  limited  partners as of December 31, 2003.  As of December  31,  2003,
$3,530,679 or $565.27 per limited partner unit has been distributed to  the
limited partners, representing a 100% return of capital and a 13% return on
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 $156,600  in
2003 compared to $25,200 in 2002 and approximately $331,200 in 2001.

Cash  flows  provided by (used in) investing activities were  approximately
$93,200 in 2003 compared to $(21,600) in 2002 and approximately $(7,200) in
2001.  The primary source of investing activities was the sales of oil  and
gas properties.

Cash flows used in financing activities were approximately $205,800 in 2003
compared  to $18,400 in 2002 and approximately $361,300 in 2001.  The  only
2003 use in financing activities was the distributions to partners.

As  of  December  31,  2003, the Partnership has approximately  $95,900  in
working  capital.  Although the Partnership held many long-lived properties
at  inception, because of the restrictions on property development  imposed
by  the  partnership  agreement, the Partnership  cannot  develop  its  non
producing properties, if any.  Without continued development, the producing
reserves continue to deplete.  Accordingly, as the Partnership's properties
have  matured  and  depleted, the net cash flows from  operations  for  the
Partnership  has  steadily  declined, except in  periods  of  substantially
increased  commodity pricing.  Maintenance of properties and administrative
expenses for the Partnership are increasing relative to production.  As the
properties   continue   to   deplete,   maintenance   of   properties   and
administrative costs as a percentage of production are expected to continue
to increase.

Liquidity - Managing General Partner
As  of  December 31, 2003, the Managing General Partner is in violation  of
several covenants pertaining to their Amended and Restated Revolving Credit
Agreement  due  June  1, 2006 and their Senior Second Lien  Secured  Credit
Agreement  due  October  15,  2008.  Due to the  covenant  violations,  the
Managing  General  Partner is in default under their Amended  and  Restated
Revolving  Credit  Agreement  and the Senior  Second  Lien  Secured  Credit
Agreement,  and all amounts due under these agreements have been classified
as  a current liability on the Managing General Partner's balance sheet  at
December 31, 2003.  The significant working capital deficit and debt  being
in default at December 31, 2003, raise substantial doubt about the Managing
General Partner's ability to continue as a going concern.

Subsequent  to  December 31, 2003, the Board of Directors of  the  Managing
General  Partner announced its decision to explore a merger,  sale  of  the
stock  or  other transaction involving the Managing General  Partner.   The
Board  has  formed a Special Committee of independent directors to  oversee
the   sales  process.   The  Special  Committee  has  retained  independent
financial  and  legal advisors to work closely with the management  of  the
Managing General Partner to implement the sales process.  There can  be  no
assurance  that a sale of the Managing General Partner will be  consummated
or what terms, if consummated, the sale will be on.

Recent Accounting Pronouncements
The  EITF is considering two issues related to the reporting of oil and gas
mineral  rights.  Issue No. 03-O, "Whether Mineral Rights Are  Tangible  or
Intangible Assets," is whether or not mineral rights are intangible  assets
pursuant  to  SFAS  No.  141,  "Business  Combinations."  Issue  No.  03-S,
"Application of SFAS No. 142, Goodwill and Other Intangible Assets, to  Oil
and  Gas  Companies,"  is, if oil and gas drilling  rights  are  intangible
assets,  whether  those  assets  are  subject  to  the  classification  and
disclosure provisions of SFAS No. 142.  The Partnership classifies the cost
of oil and gas mineral rights as properties and equipment and believes that
this is consistent with oil and gas accounting and industry practice.   The
disclosures required by SFAS Nos. 141 and 142 would be made in the notes to
the  financial  statements. There would be no effect on  the  statement  of
income  or  cash  flows as the intangible assets related  to  oil  and  gas
mineral rights would continue to be amortized under the full cost method of
accounting.

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


We  have  audited the accompanying balance sheets of Southwest  Oil  &  Gas
Income Fund X-C, L.P. (the "Partnership") as of December 31, 2003 and 2002,
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,  2003.   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 X-C, L.P. as of December 31, 2003 and 2002 and the results  of
its  operations and its cash flows for each of the years in the three  year
period  ended  December  31, 2003 in conformity with accounting  principles
generally accepted in the United States of America.

As discussed in Note 4 to the financial statements, the Partnership changed
its method of computing depletion in 2002.  Also, as discussed in Note 3 to
the  financial statements, the Partnership changed its method of accounting
for asset retirement obligations as of January 1, 2003.

                      Notes to Financial Statements

1.   Organization
     Southwest Oil & Gas Income Fund X-C, L.P. was organized under the laws
     of  the  state of Delaware on September 20, 1991, 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  sells  its  oil  and   gas
     production  to  several 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.   Revenues,  costs  and  expenses   are
     allocated as follows:
                              Limited   General
                              Partners  Partners

          contributions  will be paid by the Managing General  Partner  and
          will  be treated as a capital contribution.  The Partnership paid
          the  Managing  General Partner an amount equal to 3%  of  initial
          capital contributions for such organization costs.

          (2)  Administrative costs in any year, which exceed 2% of capital
          contributions shall be paid by the Managing General  Partner  and
          will be treated as a capital contribution.

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.

     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.  In applying the units-of-revenue  method
     for the year ended December 31, 2001, we have not excluded royalty and
     net profit interest payments from gross revenues as all of our royalty
     and  net profit interests have been purchased and capitalized  to  the
     depletion basis of our proved oil and gas properties.  As of  December
     31,  2003, 2002 and 2001 the net capitalized costs did not exceed  the
     estimated present value of the 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.

                      Notes to Financial Statements

2.   Summary of Significant Accounting Policies - continued

     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.

     Revenue Recognition
     We  recognize  oil  and gas sales when delivery to the  purchaser  has
     occurred  and title has transferred.  This occurs when production  has
     been delivered to a pipeline or transport vehicle.

     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,  2003  and  2002,
     there  were no significant amounts of imbalance in terms of  units  or
     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,  2003 and 2002 is $8,739 and $14,368 respectively, less 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.

     Number of Limited Partner Units
     As  of  December  31,  2003, 2002 and 2001 there  were  6,246  limited
     partner units outstanding held by 292, 291 and 291 partners.

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

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

2.   Summary of Significant Accounting Policies - continued

     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
     The EITF is considering two issues related to the reporting of oil and
     gas  mineral  rights.  Issue  No. 03-O, "Whether  Mineral  Rights  Are
     Tangible  or Intangible Assets," is whether or not mineral rights  are
     intangible  assets pursuant to SFAS No. 141, "Business  Combinations."
     Issue  No.  03-S,  "Application of SFAS No. 142,  Goodwill  and  Other
     Intangible  Assets,  to Oil and Gas Companies," is,  if  oil  and  gas
     drilling  rights  are  intangible assets,  whether  those  assets  are
     subject  to the classification and disclosure provisions of  SFAS  No.
     142.   The  Partnership classifies the cost of  oil  and  gas  mineral
     rights  as  properties  and  equipment  and  believes  that  this   is
     consistent  with  oil and gas accounting and industry  practice.   The
     disclosures  required by SFAS Nos. 141 and 142 would be  made  in  the
     notes  to  the financial statements. There would be no effect  on  the
     statement of income or cash flows as the intangible assets related  to
     oil  and  gas mineral rights would continue to be amortized under  the
     full cost method of accounting.

     Depletion Policy
     In  2002,  the Partnership changed methods of accounting for depletion
     of capitalized costs from the units-of-revenue method to the units-of-
     production method. (See Note 4)

3.   Cumulative effect of change in accounting principle - SFAS No. 143
     On  January  1, 2003, the Partnership adopted Statement  of  Financial
     Accounting   Standards  No.  143,  Accounting  for  Asset   Retirement
     Obligations  ("SFAS No. 143").  Adoption of SFAS No. 143  is  required
     for  all  companies with fiscal years beginning after June  15,  2002.
     The new standard requires the Partnership to recognize a liability for
     the  present  value  of  all  legal obligations  associated  with  the
     retirement  of tangible long-lived assets and to capitalize  an  equal
     amount as a cost of the asset and depreciate the additional cost  over
     the  estimated  useful  life of the asset.  On January  1,  2003,  the
     Partnership    recorded   additional   costs,   net   of   accumulated
     depreciation,  of  approximately $227,654, a long  term  liability  of
     approximately  $797,872 and a loss of approximately $570,218  for  the
     cumulative  effect  on  depreciation  of  the  additional  costs   and
     accretion  expense  on  the liability related to expected  abandonment
     costs  of  its oil and natural gas producing properties.  At  December
     31,  2003, the asset retirement obligation was $714,041.  The decrease
     in  the  balance from January 1, 2003 is due to property sales,  which
     decreased  the asset retirement obligation by $108,159  and  plug  and
     abandonment  of  oil  and gas properties, which  decreased  the  asset
     retirement  obligation  by  $35,665,  partially  offset  by  accretion
     expense of $59,917 and the addition of a well for $76.  The pro  forma
     amounts  of the asset retirement obligation as of December  31,  2002,
     2001  and  2000, were approximately $797,872, $739,149  and  $684,748,
     respectively.    The  pro  forma  amounts  of  the  asset   retirement
     obligation  were measured using information, assumptions and  interest
     rates  as  of  the adoption date of January 1, 2003.   The  pro  forma
     amounts  for  the  years ended December 31, 2002 and 2001,  which  are
     presented below, reflect the effect of retroactive application of SFAS
     No. 143.

4.    Cumulative  effect of a change in accounting principle  -  change  in
depletion method
     In  2002,  the Partnership changed methods of accounting for depletion
     of capitalized costs from the units-of-revenue method to the units-of-
     production   method.   The  newly  adopted  accounting  principle   is
     preferable in the circumstances because the units-of-production method
     results  in  a better matching of the costs of oil and gas  production
     against the related revenue received in periods of volatile prices for
     production  as have been experienced in recent periods.  Additionally,
     the  units-of-production method is the predominant method used by full
     cost  companies in the oil and gas industry, accordingly,  the  change
     improves  the comparability of the Partnership's financial  statements
     with  its peer group.  The Partnership adopted the units-of-production
     method  through the recording of a cumulative effect of  a  change  in
     accounting principle in the amount of $128,000 effective as of January
     1,  2002.   The Partnership's depletion for the years ended  2003  and
     2002  have  been calculated using the units-of-production  method  and
     2001 has not been restated.  The pro forma amounts for 2001, which are
     presented below, reflect the effect of retroactive application of  the
     units-of-production method.  See Note 12 for the effects of the change
     in depletion method on the individual quarters of 2002.

5.   Discontinued Operations - Sale of oil and gas leases
     During 2003, the Partnership sold its interest in certain oil and  gas
     wells  for  $142,384  sales  proceeds and retired  $108,159  of  asset
     retirement  obligation  associated with  the  properties.   Since  the
     Partnership  is  under the full cost pool method  of  accounting,  the
     sales  proceeds and asset retirement obligation liability  were  taken
     against  the  oil and gas properties asset account and  therefore,  no
     gain or loss was recorded and shown on the statement of operations  as
     part of the discontinued operations.  Pursuant to the requirements  of
     SFAS  No.  144, the historical operating results from these properties
     have  been  reported  as discontinued operations in  the  accompanying
     statements  of  operations.  The following  table  summarizes  certain
     historical   operating  information  related   to   the   discontinued
     operations:

                    2003       2002      2001

Revenues          $115,834   120,285   222,982
Net income        49,177     25,299    124,296

6.   Liquidity - Managing General Partner
     As  of December 31, 2003, the Managing General Partner is in violation
     of   several  covenants  pertaining  to  their  Amended  and  Restated
     Revolving  Credit Agreement due June 1, 2006 and their  Senior  Second
     Lien  Secured  Credit  Agreement due October 15,  2008.   Due  to  the
     covenant violations, the Managing General Partner is in default  under
     their  Amended and Restated Revolving Credit Agreement and the  Senior
     Second Lien Secured Credit Agreement, and all amounts due under  these
     agreements have been classified as a current liability on the Managing
     General Partner's balance sheet at December 31, 2003.  The significant
     working  capital  deficit and debt being in default  at  December  31,
     2003,  raise  substantial doubt about the Managing  General  Partner's
     ability to continue as a going concern.

     Subsequent  to  December  31, 2003, the  Board  of  Directors  of  the
     Managing  General Partner announced its decision to explore a  merger,
     sale  of the stock or other transaction involving the Managing General
     Partner.   The  Board  has formed a Special Committee  of  independent
     directors  to  oversee the sales process.  The Special  Committee  has
     retained independent financial and legal advisors to work closely with
     the  management of the Managing General Partner to implement the sales
     process.   There  can  be no assurance that a  sale  of  the  Managing
     General Partner will be consummated or what terms, if consummated, the
     sale will be on.

                      Notes to Financial Statements

7.   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, 2003, 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.

8.   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  $136,700,
     $160,900 and $180,000, respectively, for the years ended December  31,
     2003,  2002  and 2001.  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.

     Southwest  Royalties,  Inc., the Managing General  Partner,  was  paid
     $36,000  during  2003,  2002 and 2001, as an administrative  fee,  for
     indirect   general   and   administrative   overhead   expenses.   The
     administrative fees are included in general and administrative expense
     on the statement of operations.

     Receivables  from  Southwest  Royalties, Inc.,  the  Managing  General
     Partner,  of  approximately $38,800 and $82,000 are from oil  and  gas
     production, net of lease operating costs and production taxes,  as  of
     December 31, 2003 and 2002, respectively.

9.   Major Customers
     The  Managing General Partner intends that no material portion of  the
     Partnership's business is dependent on a single purchaser, or  a  very
     few  purchasers,  where the loss of one would have a material  adverse
     impact  on the Partnership.  Two purchasers accounted for 82%  of  the
     Partnership's total oil and gas production during 2003:  Teppco  Crude
     Oil  LLC  for  72%  and Plains Marketing LP for 10%.   Two  purchasers
     accounted  for  80% of the Partnership's total oil and gas  production
     during 2002: Teppco Crude Oil LLC for 68% and Plains Marketing LP  for
     12%.   Three  purchasers accounted for 85% of the Partnership's  total
     oil  and  gas  production during 2001: Teppco Crude Oil LLC  for  60%,
     George  L  Mcleod Inc. for 14% and Plains Marketing LP for  11%.   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.

10.  Subsequent Event
     Subsequent  to  December  31,  2003,  the  Managing  General   Partner
     announced that its Board of Directors had decided to explore a  merger
     or  sale  of  the  stock of the Company.  The Board formed  a  Special
     Committee  of independent directors to oversee the sale process.   The
     Special Committee retained independent financial and legal advisors to
     work closely with management to implement the sale process.

     On  May  3,  2004, the Managing General Partner entered  into  a  cash
     merger  agreement to sell all of its stock to Clayton Williams Energy,
     Inc.  The cash merger price is being negotiated, but is expected to be
     approximately  $45 per share.  The transaction, which  is  subject  to
     approval  by the Managing General Partner's shareholders, is  expected
     to close no later than May 21, 2004.

11.  Estimated Oil and Gas Reserves (unaudited) - continued
     *Ryder Scott Company, L.P. prepared the reserve and present value data
     for  the Partnership's existing properties as of January 1, 2004.  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, 2004, 2003 and  2002  are  an
     average price of $29.48, $27.85 and $18.48 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,  2004, 2003 and 2002 are an average price of $3.83,  $3.58
     and $1.85 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.

     Partnership  has  reserves, which are classified as proved  developed.
     All  of  the proved reserves are included in the engineering  reports,
     which evaluate the Partnership's present reserves.

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

12.  Selected Quarterly Financial Results - (unaudited) - continued
     As  discussed  in Note 4, in 2002 the Partnership changed  methods  of
     accounting  for  depletion  of capitalized costs  from  the  units-of-
     revenue  method to the units-of-production method.  The 2002 quarterly
     financial  results  presented below reflect the  change  in  depletion
     method effective as of January 1, 2002.

     effective  in  ensuring  that  material  information  required  to  be

     the  Exchange  Act was accumulated and communicated  to  the  Managing
     General  Partner's  management,  including  its  President  and  Chief
     Executive Officer and Chief Financial Officer, as appropriate to allow
     timely decisions regarding required disclosure.

engineers   and   geologists  in  connection  with  property  acquisitions,
geological  and  geophysical  analysis,  and  reservoir  engineering.   The

more economically and effectively.

Code of Ethics

Neither the Partnership nor the Managing General Partner has adopted a code
of  ethics  for  employees, or any principal executive officers,  principal
financial officers, principal accounting officers or the Board of Directors
of the Managing General Partner.  The Board of the Managing General Partner
believes  that  the Partnership's existing internal control procedures  and
current business practices are adequate to promote ethical conduct  and  to
deter  wrongdoing  on the part of these executives.  The  Managing  General
Partner  of  the  Partnership intends to implement during 2004  a  code  of
ethics  that will apply to these executives.  In accordance with applicable
SEC rules, the code of ethics will be made publicly available.

10A(m)(3) of the Securities Exchange Act of 1934, as amended, and the rules
and regulations promulgated thereunder.

Item 13.  Certain Relationships and Related Transactions

In 2003, the Managing General Partner received $36,000 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 $136,700 for administrative  overhead
attributable to operating such properties during 2003.

The  terms of the above transactions are similar to ones, which would  have
been  obtained  through arm's length negotiations with  unaffiliated  third
parties.
