                                  Part I

Item 1.   Business

General
Southwest  Oil  &  Gas  Income  Fund  IX-A,  L.P.  (the  "Partnership"   or
"Registrant") was organized as a Delaware limited partnership on  March  9,
1989.   The  offering of limited partnership interests began May 11,  1989,
reached  minimum  capital requirements on October 25,  1989  and  concluded
March 31, 1990.  The Partnership has no subsidiaries.

The  Partnership  has  expended  its  capital  and  acquired  interests  in
producing oil and gas properties.  After such acquisitions, the Partnership
has  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,  with an occasional purchase  of  a  royalty  or
overriding royalty interest.  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  97  individuals,  together  with   certain
independent  consultants  used  on an "as needed"  basis,  perform  various
services on behalf of the Partnership, including the selection of  oil  and
gas properties and the marketing of production from such properties.  H. H.
Wommack,  III,  a  stockholder, director, President and  Treasurer  of  the
Managing  General Partner, is also a general partner.  The Partnership  has
no employees.

Principal Products, Marketing and Distribution
The  Partnership has acquired and holds working interests in  oil  and  gas
properties  located  in  Texas  and New  Mexico.   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>
Oil prices experienced a year of recovery during 1999.  After seeing prices
languish  near  $10  per barrel in December 1998, a rebound  occurred  that
would briefly push NYMEX pricing over $27 in late November 1999.  Crude oil
prices reached $20 per barrel in mid-July and would not fall below $21  the
rest of the year.  There were drastic improvements to the main factors that
gave  rise  to  the worst price depression in history.  These  improvements
provoked a spike in crude oil prices to levels not seen since the Gulf War.
First, OPEC has done a remarkable job of adhering to production cuts agreed
to  in  March, despite the temptation to cheat given current  pricing.   As
prices  have  risen  over  the last twelve months,  OPEC  has  consistently
maintained a compliance rate above 90 percent.  Also, most foreign  markets
are well on their way to recovery, greatly increasing the demand for energy
in   those  countries.   These  and  other  factors  have  eliminated   the
"oversupply"  of  crude oil that we experienced in 1998.   The  near  month
contract for crude oil settled at $25.60 per barrel on December 30, 1999.

In  1999  natural  gas  prices rose 10% to an average of  $2.18/MMBtu,  18 cents
higher  than  the  $2.00/MMBtu average seen in 1998.  Despite  warmer-than-
normal  heating seasons at both ends of the year, 1999 was the fourth  year
in  a  row that prices averaged $2.00/MMBtu or above.  Citing lower storage
levels and a rising demand for natural gas, industry experts are predicting
a "healthy jump" in prices for 2000.  Although higher prices in 1999 fueled
an  increase in production, end of year gas in storage nationwide  is  only
75% of capacity as compared to 87% at the end of 1998.  Further, gas demand
is expected to continue to increase at a faster pace than the amount of gas
being replaced.  A record breaking 70% of single-family homes built in 1999
were equipped with natural gas services ranging from traditional heating to
water   heating,   cooking  and  grilling.   Based  on  these   encouraging
statistics,  we  remain optimistic in our expectation  of  slightly  higher
natural  gas  prices in the coming year, hopefully seeing an average  above
the $2.20/MMBtu level.

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

                                  Oil          Gas

                    1999          61%          39%
                    1998          62%          38%
                    1997          61%          39%

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

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

<PAGE>
Customer Dependence
No  material portion of the Partnership's business is dependent on a single
purchaser,  or a very few purchasers, where the loss of one  would  have  a
material  adverse impact on the Partnership.  Two purchasers accounted  for
72%  of  the  Partnership's  total  oil and  gas  production  during  1999:
Phillips  66  Company  for  60% and Scurlock  Permian  LLC  for  12%.   Two
purchasers  accounted  for  68%  of the Partnership's  total  oil  and  gas
production during 1998:  Phillips 66 Company for 58%, and Scurlock  Permian
Corporation for 10%.  Two purchasers accounted for 69% of the Partnership's
total oil and gas production during 1997:  Phillips 66 Company for 59%, and
Scurlock Permian Corporation 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,  it  is  not
subject  to  competition from other oil and gas property  purchasers.   See
Item 2, Properties.

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

Regulation

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

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

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

Industry  Regulations  and  Guidelines - Certain industry  regulations  and
guidelines  apply to the registration, qualification and operation  of  oil
and  gas programs in the form of limited partnerships.  The Partnership  is
subject  to  these  guidelines  which regulate  and  restrict  transactions
between the Managing General Partner and the Partnership.

The  Partnership  complies with these guidelines and the  Managing  General
Partner  does not anticipate that continued compliance will have a material
adverse effect on Partnership operations.

Partnership Employees
The  Partnership has no employees; however the Managing General Partner has
a  staff of geologists, engineers, accountants, landmen and clerical  staff
who  engage in Partnership activities and operations and perform additional
services  for  the  Partnership as needed.  In  addition  to  the  Managing
General  Partner's  staff, the Partnership engages independent  consultants
such  as petroleum engineers and geologists as needed.  As of December  31,
1999,  there were 97 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.

<PAGE>
As  of December 31, 1999, the Partnership possessed an interest in oil  and
gas  properties  located in Eddy and Lea Counties of New  Mexico;  Andrews,
Crane,  Ector,  Garza, Howard, Martin, Pecos, Reagan, Stonewall,  Ward  and
Winkler  Counties of Texas.  These properties consist of various  interests
in approximately 160 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 has not been any
significant changes in properties during 1999, 1998 and 1997.

During  1999,  four  leases were sold for approximately  $200,950.   During
1998,  fifteen leases were sold for approximately $141,400.   During  1997,
there were no property sales.

<PAGE>
*Donald  R.  Creamer,  P.E., an Independent Registered  Petroleum  Engineer
prepared  the reserve and present value data for the Partnership's existing
properties  as  of  January 1, 2000.  The reserve estimates  were  made  in
accordance  with  guidelines  established by the  Securities  and  Exchange
Commission  pursuant  to Rule 4-10(a) of Regulation S-X.   Such  guidelines
require oil and gas reserve reports be prepared under existing economic and
operating  conditions  with  no provisions for price  and  cost  escalation
except by contractual arrangements.

The  New York Mercantile Exchange price at December 31, 1999 of $25.60  was
used  as the beginning basis for the oil price.  Oil price adjustments from
$25.60  per  barrel were made in the individual evaluations to reflect  oil
quality,  gathering and transportation costs.  The results are  an  average
price received at the lease of $23.73 per barrel in the preparation of  the
reserve report as of January 1, 2000.

In  the  determination of the gas price, the New York  Mercantile  Exchange
price  at December 31, 1999 of $2.33 was used as the beginning basis.   Gas
price   adjustments  from  $2.33  per  Mcf  were  made  in  the  individual
evaluations to reflect BTU content, gathering and transportation costs  and
gas processing and shrinkage.  The results are an average price received at
the  lease of $1.90 per Mcf in the preparation of the reserve report as  of
January 1, 2000.

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 1999.

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

Unanticipated  depletion, if it occurs, will result in lower reserves  than
previously  estimated; thus an ultimately lower return for the Partnership.
Basic  changes in past reserve estimates occur annually.  As  new  data  is
gathered  during the subsequent year, the engineer must revise his  earlier
estimates.  A year of new information, which is pertinent to the estimation
of  future  recoverable volumes, is available during  the  subsequent  year
evaluation.

<PAGE>
In  applying industry standards and procedures, the new data may cause  the
previous  estimates to be revised.  This revision may increase or  decrease
the  earlier estimated volumes.  Pertinent information gathered during  the
year  may  include  actual production and decline  rates,  production  from
offset wells drilled to the same geologic formation, increased or decreased
water  production, workovers, and changes in lifting costs,  among  others.
Accordingly,  reserve estimates are often different from the quantities  of
oil and gas that are ultimately recovered.

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

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

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

Item 3.   Legal Proceedings

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

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

No  matter  was submitted to a vote of security holders during  the  fourth
quarter of 1999 through the solicitation of proxies or otherwise.

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

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

The  Managing  General Partner has the right, but not  the  obligation,  to
purchase limited partnership units should an investor desire to sell.   The
value  of  the unit is determined  by adding the sum of (1) current  assets
less  liabilities  and  (2) the present value of the  future  net  revenues
attributable to proved reserves and by discounting the future net  revenues
at  a rate not in excess of the prime rate charged by NationsBank, N.A.  of
Midland, Texas plus one percent (1%), which value shall be further  reduced
by  a risk factor discount of no more than one-third (1/3) to be determined
by  the  Managing General Partner in its sole and absolute discretion.   In
1999,  30  limited  partner units were tendered to  and  purchased  by  the
Managing  General Partner at an average base price of $63.19 per unit.   In
1998,  68  limited  partner units were tendered to  and  purchased  by  the
Managing  General Partner at an average base price of $66.48 per unit.   In
1997,  16  limited  partner units were tendered to  and  purchased  by  the
Managing General Partner at an average base price of $120.36 per unit.

Number of Limited Partner Interest Holders
As of December 31, 1999, there were 568 holders of limited partner units in
the Partnership.

Distributions
Pursuant  to Article IV, Section 4.01 of the Partnership's Certificate  and
Agreement  of  Limited Partnership "Net Cash Flow" is  distributed  to  the
partners  on  a  monthly basis.  "Net Cash Flow" is defined  as  "the  cash
generated  by  the  Partnership's investments  in  producing  oil  and  gas
properties,  less  (i)  General and Administrative  Costs,  (ii)  Operating
Costs,  and  (iii) any reserves necessary to meet current  and  anticipated
needs  of  the  Partnership, as determined in the sole  discretion  of  the
Managing General Partner."

<PAGE>
During  1999,  distributions  were made totaling  $262,173,  with  $238,173
distributed  to  the limited partners and $24,000 to the general  partners.
For  the  year ended December 31, 1999, distributions of $22.79 per limited
partner   unit   were  made,  based  upon  10,453  limited  partner   units
outstanding.  During 1998, distributions were made totaling $268,773,  with
$244,923  distributed to the limited partners and $23,850  to  the  general
partners.   For the year ended December 31, 1998, distributions  of  $23.43
per limited partner unit were made, based upon 10,453 limited partner units
outstanding.  During 1997, twelve monthly distributions were made  totaling
$442,000, with $397,800 distributed to the limited partners and $44,200  to
the  general partners.  For the year ended December 31, 1997, distributions
of  $38.06  per  limited partner unit were made, based upon 10,453  limited
partner units outstanding.

Item 6.   Selected Financial Data

The  following  selected financial data for the years  ended  December  31,

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  has fluctuated over the past couple of years and is  expected  to
fluctuate in later years based on these factors.

Based  on  current conditions, management anticipates performing  workovers
during 2000 to enhance production.  The partnership may have an increase in
production  volumes for the years 2000 and 2001, otherwise, the partnership
will   most   likely  experience  the  historical  production  decline   of
approximately 7% per year.

A.  General Comparison of the Years Ended December 31, 1999 and 1998

The  following  table  provides certain information  regarding  performance
factors for the years ended December 31, 1999 and 1998:

                                                  Year Ended     Percentage
                                                 December 31,     Increase
                                                1999      1998   (Decrease)
                                                ----      ----   ---------

Average price per barrel of oil            $    16.87     12.41     36%
Average price per mcf of gas               $     1.97      1.55     27%
Oil production in barrels                      26,560    35,100   (24%)
Gas production in mcf                         143,200   173,100   (17%)
Gross oil and gas revenue                  $  729,841   704,238      4%
Net oil and gas revenue                    $  339,531   215,591     57%
Partnership distributions                  $  262,173   268,773    (2%)
Limited partner distributions              $  238,173   244,923    (3%)
Per unit distribution to limited partners  $    22.79     23.43    (3%)
Number of limited partner units                10,453    10,453

Revenues

The  Partnership's oil and gas revenues increased to $729,841 from $704,238
for  the  years ended December 31, 1999 and 1998, respectively, an increase
of  4%.  The principal factors affecting the comparison of the years  ended
December 31, 1999 and 1998 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the year ended December 31, 1999 as compared  to  the
    year ended December 31, 1998 by 36%, or $4.46 per barrel, resulting  in
    an   increase  of  approximately  $156,500  in  revenues.   Oil   sales
    represented  61%  of  total oil and gas sales  during  the  year  ended
    December 31, 1999 as compared to 62% during the year ended December 31,
    1998.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 27%, or $.42 per mcf, resulting  in
    an increase of approximately $72,700 in revenues.

    The  total  increase in revenues due to the change in  prices  received
    from  oil  and  gas production is approximately $229,200.   The  market
    price  for oil and gas has been extremely volatile over the past decade
    and  management expects a certain amount of volatility to  continue  in
    the foreseeable future.

<PAGE>
2.   Oil production decreased approximately 8,540 barrels or 24% during the
   year ended December 31, 1999 as compared to the year ended December  31,
   1998, resulting in a decrease of approximately $144,100 in revenues.

    Gas  production  decreased approximately 29,900 mcf or 17%  during  the
    same  period,  resulting  in  a decrease of  approximately  $58,900  in
    revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $203,000.  The decrease in production is primarily due to
    property sales in 1998 and 1999.

Costs and Expenses

Total  costs and expenses decreased to $497,166 from $701,160 for the years
ended  December 31, 1999 and 1998, respectively, a decrease  of  29%.   The
decrease  is  the result of lower depletion expense, lease operating  costs
and general and administrative costs.

1.    Lease  operating  costs  and production  taxes  were  20%  lower,  or
   approximately $98,300 less during the year ended December  31,  1999  as
   compared  to  the year ended December 31, 1998.  The decrease  in  lease
   operating cost are due primarily to property sales in 1998 and 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 $14,700 during the year ended December 31, 1999 as
    compared to the year ended December 31, 1998.  The decrease of  general
    and  administrative  costs  were due in part to  additional  accounting
    costs  incurred  in  1998  in relation to the outsourcing  of  K-1  tax
    package  preparation and a change in auditors requiring  opinions  from
    both  the  predecessors  and  successor  auditors.   Additionally,  the
    Managing  General  Partner in its effort to cut  back  on  general  and
    administrative costs whenever and wherever possible was able to  reduce
    the  cost  of  reserve reports and K-1 tax package  preparation  during
    1999.

3.  Depletion expense decreased to $28,000 for the year ended December  31,
    1999  from  $119,000 for the same period in 1998.   This  represents  a
    decrease  of 76%.  Depletion is calculated using the units  of  revenue
    method  of  amortization based on a percentage of current period  gross
    revenues  to  total future gross oil and gas revenues, as estimated  by
    the Partnership's independent petroleum consultants.

    A  contributing factor to the 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, 2000 as compared
    to   1999.   Additionally,  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 $50,000 as of December 31, 1998.

B.  General Comparison of the Years Ended December 31, 1998 and 1997

The  following  table  provides certain information  regarding  performance
factors for the years ended December 31, 1998 and 1997:

                                                  Year Ended     Percentage
                                                 December 31,     Increase

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

Average price per barrel of oil            $    12.41     18.52   (33%)
Average price per mcf of gas               $     1.55      2.04   (24%)
Oil production in barrels                      35,100    35,800    (2%)
Gas production in mcf                         173,100   205,200   (16%)
Gross oil and gas revenue                  $  704,238 1,082,153   (35%)
Net oil and gas revenue                    $  215,591   453,599   (52%)
Partnership distributions                  $  268,773   442,000   (39%)
Limited partner distributions              $  244,923   397,800   (38%)
Per unit distribution to limited partners  $    23.43     38.06   (38%)
Number of limited partner units                10,453    10,453

Revenues

The   Partnership's  oil  and  gas  revenues  decreased  to  $704,238  from
$1,082,153 for the years ended December 31, 1998 and 1997, respectively,  a
decrease  of  35%.  The principal factors affecting the comparison  of  the
years ended December 31, 1998 and 1997 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the year ended December 31, 1998 as compared  to  the
    year ended December 31, 1997 by 33%, or $6.11 per barrel, resulting  in
    a   decrease  of  approximately  $218,700  in  revenues.    Oil   sales
    represented  62%  of  total oil and gas sales  during  the  year  ended
    December 31, 1998 as compared to 61% during the year ended December 31,
    1997.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    decreased during the same period by 24%, or $.49 per mcf, resulting  in
    a decrease of approximately $100,500 in revenues.

    The  total  decrease in revenues due to the change in  prices  received
    from  oil  and  gas production is approximately $319,200.   The  market
    price  for oil and gas has been extremely volatile over the past decade
    and  management expects a certain amount of volatility to  continue  in
    the foreseeable future.

<PAGE>
2.   Oil  production decreased approximately 700 barrels or 2%  during  the
   year ended December 31, 1998 as compared to the year ended December  31,
   1997, resulting in a decrease of approximately $8,700 in revenues.

    Gas  production  decreased approximately 32,100 mcf or 16%  during  the
    same  period,  resulting  in  a decrease of  approximately  $49,800  in
    revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $58,500.  The decrease in gas production is due primarily
    to  downtime  on one well and a fairness letter issued on  a  gas  well
    which decreases the Partnerships percentage of ownership.

Costs and Expenses

Total  costs and expenses decreased to $701,160 from $832,286 for the years
ended  December 31, 1998 and 1997, respectively, a decrease  of  16%.   The
decrease  is  the  result of lower depletion expense  and  lease  operating
costs, partially offset by an increase in general and administrative costs.

2.    Lease  operating  costs  and production  taxes  were  22%  lower,  or
   approximately $139,900 less during the year ended December 31,  1998  as
   compared  to  the  year ended December 31, 1997.  The decline  in  lease
   operating  costs are due primarily to property sales and a  decrease  in
   advalorem taxes.

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 $10,800 during the year ended December 31, 1998 as
    compared to the year ended December 31, 1997.

3.  Depletion expense decreased to $119,000 for the year ended December 31,
    1998  from  $121,000 for the same period in 1997.   This  represents  a
    decrease  of  2%.  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.

    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 $8,000 as of December 31, 1997.

C.  Revenue and Distribution Comparison

Partnership net income for the years ended December 31, 1999, 1998 and 1997
was $237,535, $6,584 and $251,561, respectively.  Excluding the effects  of
depreciation,  depletion  and amortization,  net  income  would  have  been
$265,535  in 1999, $125,584 in 1998 and $372,561 in 1997.  Correspondingly,
Partnership distributions for the years ended December 31, 1999,  1998  and
1997 were $262,173, $268,773 and $442,000, respectively.  These changes are
indicative  of the changes in oil and gas prices, production and properties
during 1999, 1998 and 1997.

The  sources  for  the  1999 distributions of $262,173  were  oil  and  gas
operations  of  approximately  $201,300 and  the  change  in  oil  and  gas
properties  $195,800,  resulting  in  excess  cash  for  contingencies   or
subsequent  distributions.   The  sources for  the  1998  distributions  of
$268,773  were  oil and gas operations of approximately  $173,200  and  the
change in oil and gas properties of approximately $91,000, with the balance
from  available cash on hand at the beginning of the period.   The  sources
for  the  1997  distributions of $442,000 were oil and  gas  operations  of
approximately  $470,600  and  the change  in  oil  and  gas  properties  of
approximately  $(16,300),  resulting in excess cash  for  contingencies  or
subsequent distributions.

Total  distributions during the year ended December 31, 1999 were  $262,173
of  which  $238,173 was distributed to the limited partners and $24,000  to
the general partners.  The per unit distribution to limited partners during
the  same  period was $22.79.  Total distributions during  the  year  ended
December  31, 1998 were $268,773 of which $244,923 was distributed  to  the
limited  partners  and  $23,850  to the general  partners.   The  per  unit
distribution to limited partners during the same period was $23.43.   Total
distributions  during  the year ended December 31, 1997  were  $442,000  of
which  $397,800 was distributed to the limited partners and $44,200 to  the
general partners.  The per unit distribution to limited partners during the
same period was $38.06.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $6,178,964  have been made to the partners.  As of December  31,  1999,
$5,619,646 or $537.61 per limited partner unit, has been distributed to the
limited partners, representing a 108% return of the capital contributed.

<PAGE>
Liquidity and Capital Resources

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

Cash flows provided by operating activities were approximately $201,300  in
1999 compared to $173,200 in 1998 and approximately $470,600 in 1997.   The
primary  source  of  the  1999  cash flow  from  operating  activities  was
profitable operations.

Cash   flows   (used   in)  or  provided  by  investing   activities   were
approximately,  $195,800  in  1999  compared  to  $91,000   in   1998   and
approximately  $(16,300) in 1997.  The principal source of  the  1999  cash
flow from investing activities was the sale of oil and gas properties.

Cash flows used in financing activities were approximately $262,700 in 1999
compared to $268,300 in 1998 and approximately $442,000 in 1997.  The  only
use in financing activities was the distributions to partners.

As  of  December  31, 1999, the Partnership had approximately  $252,605  in
working  capital.   The  Managing  General  Partner  knows  of  no  unusual
contractual commitments and believes the revenues generated from operations
are adequate to meet the needs of the Partnership.

Liquidity - Managing General Partner

The  Managing General Partner has a highly leveraged capital structure with
over  $35.1  million principal and $17.5 million interest payments  due  in
2000  on  its  debt  obligations. Due to the severely  depressed  commodity
prices  experienced  during the last quarter of 1997, throughout  1998  and
continuing through the second quarter of 1999 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.

Information Systems for the Year 2000

The  year  2000  issue  referred to the risk of disruptions  of  operations
caused  by  the  failure of computer-controlled systems, including  systems
used  by  third  parties, to properly recognize date sensitive  information
when  the  year changed from 1999 to 2000.  During the year ended  December
31, 1999, the Managing General Partners data processing subsidiary, Midland
Southwest  Software, Inc., installed new software as part  of  an  on-going
project  to upgrade its financial and management information systems.   The
cost  of  upgrading the software occurred in the normal course  of  Midland
Southwest  Software's  business and was not  material  to  the  results  of
operations or financial condition of the Partnership.

The  Partnership  has not experienced any significant business  disruptions
due  to  year  2000 issues causing processing errors in its systems,  or  a
third  party's  systems, during the period of operations after  January  1,
2000 until the filing of the 10-K.

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


We  have  audited the accompanying balance sheets of Southwest  Oil  &  Gas
Income  Fund  IX-A, L.P. (the "Partnership") as of December  31,  1999  and
1998, 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,  1999.  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 generally  accepted  auditing
standards.  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 IX-A, L.P. as of December 31, 1999 and 1998 and the results  of
its  operations and its cash flows for each of the years in the  three-year
period  ended  December  31,  1999 in conformity  with  generally  accepted
accounting principles.

     Southwest  Oil  & Gas Income Fund IX-A, L.P. was organized  under  the
     laws  of  the state of Delaware on March 9, 1989, 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  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.  Revenues, costs  and  expenses  are
     allocated as follows:

2.   Summary of Significant Accounting Policies

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

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

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

     Should the net capitalized costs exceed the estimated present value of
     oil  and  gas reserves, discounted at 10%, such excess costs would  be
     charged  to current expense.  As of December 31, 1999, 1998  and  1997
     the  net capitalized costs did not exceed the estimated present  value
     of oil and gas reserves.

     Estimates and Uncertainties
     The  preparation of financial statements in conformity with  generally
     accepted  accounting principles requires management to make  estimates
     and  assumptions  that  affect  the reported  amounts  of  assets  and
     liabilities and disclosure of contingent assets and liabilities at the
     date  of the financial statements and the reported amounts of revenues
     and expenses during the reporting period.  Actual results could differ
     from those estimates.

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

2.   Summary of Significant Accounting Policies - continued

     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,  1999,  the
     Partnership  was  overproduced by 403 mcf of gas. As of  December  31,
     1998 and 1997 the Partnership was overproduced by 415 mcf of gas.

     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, 1999 and 1998 is $53,388 and $13,955 more, respectively, 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.

2.   Summary of Significant Accounting Policies - continued

     Number of Limited Partner Units
     As  of  December 31, 1999, 1998 and 1997 and there were 10,453 limited
     partner units outstanding held by 568, 575 and 575 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.

3.   Liquidity - Managing General Partner
     The  Managing General Partner has a highly leveraged capital structure
     with  over $35.1 million principal and $17.5 million interest payments
     due  in  2000 on its debt obligations.  Due to the severely  depressed
     commodity  prices  experienced  during  the  last  quarter  of   1997,
     throughout 1998 and continuing through the second quarter of 1999  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.

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, 1999, the Partnership has not been fined, cited or
     notified of any environmental violations and management was 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
     determinable  due to several factors, including the unknown  magnitude
     of  possible  contaminations, the unknown timing  and  extent  of  the
     corrective  actions  which may be required, the determination  of  the
     Partnership's liability in proportion to other responsible parties and
     the  extent to which such expenditures are recoverable from  insurance
     or indemnifications from prior owners of Partnership's properties.

5.   Related Party Transactions
     A  significant  portion  of the oil and gas properties  in  which  the
     Partnership  has  an interest are operated by and purchased  from  the
     Managing General Partner.  As is usual in the industry and as provided
     for  in  the  operating  agreement for each  respective  oil  and  gas
     property  in  which the Partnership has an interest, the  operator  is
     paid  an  amount for administrative overhead attributable to operating
     such  properties,  with such amounts to Southwest Royalties,  Inc.  as
     operator  approximating $77,900, $92,400 and  $95,000  for  the  years
     ended  December 31, 1999, 1998 and 1997, respectively.   In  addition,
     the  Managing  General Partner and certain officers and employees  may
     have  an interest in some of the properties that the Partnership  also
     participates.

     Certain  subsidiaries  or affiliates of the Managing  General  Partner
     perform  various  oilfield  services  for  properties  in  which   the
     Partnership  owns an interest.  Such services aggregated approximately
     $18,500,  $4,100 and $40 for the years ended December 31,  1999,  1998
     and 1997, respectively, and the Managing General Partner believes that
     these  costs are comparable to similar charges paid by the Partnership
     to unrelated third parties.

     Southwest  Royalties,  Inc., the Managing General  Partner,  was  paid
     $73,200  during  1999,  1998  and 1997 as an  administrative  fee  for
     indirect general and administrative overhead expenses.

     Receivables  from  Southwest  Royalties, Inc.,  the  Managing  General
     Partner,  of  approximately $99,200 and $34,900 are from oil  and  gas
     production, net of lease operating costs and production taxes,  as  of
     December 31, 1999 and 1998, 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, 1999, 1998 and 1997.

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.   Two
     purchasers  accounted for 72% of the Partnership's total oil  and  gas
     production  during  1999:  Phillips 66 Company for 60%,  and  Scurlock
     Permian  LLC  for  12%.   Two  purchasers accounted  for  68%  of  the
     Partnership's total oil and gas production during 1998:   Phillips  66
     Company  58%,  and Scurlock Permian Corporation  10%.  Two  purchasers
     accounted  for  69% of the Partnership's total oil and gas  production
     during   1997:    Phillips  66  Company  59%,  and  Scurlock   Permian
     Corporation   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.

     made  in accordance with guidelines established by the Securities  and
     Exchange Commission pursuant to Rule 4-10(a) of Regulation S-X.   Such
     guidelines  require  oil  and gas reserve reports  be  prepared  under
     existing  economic  and operating conditions with  no  provisions  for
     price and cost escalation except by contractual arrangements.

     The  New York Mercantile Exchange price at December 31, 1999 of $25.60
     was  used  as  the  beginning basis for  the  oil  price.   Oil  price
     adjustments  from  $25.60  per  barrel were  made  in  the  individual
     evaluations  to  reflect  oil  quality, gathering  and  transportation
     costs.   The  results are an average price received at  the  lease  of
     $23.73  per  barrel  in the preparation of the reserve  report  as  of
     January 1, 2000.

7.   Estimated Oil and Gas Reserves (unaudited) - continued
     In  the  determination  of  the gas price,  the  New  York  Mercantile
     Exchange price at December 31, 1999 of $2.33 was used as the beginning
     basis.   Gas  price adjustments from $2.33 per Mcf were  made  in  the
     individual   evaluations  to  reflect  BTU  content,   gathering   and
     transportation  costs and gas processing and shrinkage.   The  results
     are  an  average price received at the lease of $1.90 per Mcf  in  the
     preparation of the reserve report as of January 1, 2000.

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

     Unanticipated  depletion, if it occurs, will result in lower  reserves
     than  previously estimated; thus an ultimately lower  return  for  the
     Partnership.  Basic changes in past reserve estimates occur  annually.
     As  new data is gathered during the subsequent year, the engineer must
     revise  his  earlier estimates.  A year of new information,  which  is
     pertinent  to  the  estimation  of  future  recoverable  volumes,   is
     available during the subsequent year evaluation.

     In  applying industry standards and procedures, the new data may cause
     the  previous estimates to be revised.  This revision may increase  or
     decrease   the  earlier  estimated  volumes.   Pertinent   information
     gathered  during  the year may include actual production  and  decline
     rates,  production  from offset wells drilled  to  the  same  geologic
     formation,  increased  or decreased water production,  workovers,  and
     changes   in  lifting  costs,  among  others.   Accordingly,   reserve
     estimates are often different from the quantities of oil and gas  that
     are ultimately recovered.

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

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

fee.

Item 12.  Security Ownership of Certain Beneficial Owners and Management

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

The  Managing  General Partner owns a nine percent interest  as  a  general
partner.   Through repurchase offers to the limited partners, the  Managing
General Partner also owns 292 limited partner units, a 2.8% limited partner
interest.  The Managing General Partner total percentage interest ownership
in the Partnership is 11.5%.

Item 13.  Certain Relationships and Related Transactions

In 1999, the Managing General Partner received $73,200 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 $77,900 for administrative  overhead
attributable to operating such properties during 1999.

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 $18,500  for  the  year
ended December 31, 1999.

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