     the  laws of the state of Delaware on January 7, 1991 for the  purpose
     of  drilling  developmental and exploratory wells 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.  Revenues,  costs  and
     expenses are allocated as follows:

                                                     Managing

     of  their  capital contributions, the allocation will  change  to  15%

     contributions shall be paid by the Managing General Partner  and  will

offering  period in an amount equal to 1% of its net capital contributions.
The  Managing General Partner's contribution was $9,800.  The total capital
contributions are $1,154,300.

The  Partnership was formed to engage primarily in the business of drilling
developmental  and exploratory wells, to produce and market crude  oil  and
natural  gas produced from such properties, to distribute any net  proceeds
from  operations  to the general and investor partners and  to  the  extent
necessary,  acquire leases which contain drilling prospects.  Net  revenues
will  not  be  reinvested in other revenue producing assets except  to  the
extent  that  performance of remedial work is needed to  improve  a  well's
producing capabilities.  The economic life of the Partnership thus  depends
on  the  period  over  which the Partnership's oil  and  gas  reserves  are
economically recoverable.

The  Partnership has expended its capital and acquired leasehold  interests
and  completed drilling operations.  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,  increases  and decreases in  lease  operating  expenses,
enhanced recovery projects, offset drilling activities pursuant to farm-out
arrangements, sales of properties, and 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 partners  is
therefore expected to fluctuate in later years based on these factors.

Based  on  current  conditions, management anticipates the  possibility  of
performing workovers.  The Partnership could possibly experience  a  normal
decline.

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.

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 September 30, 1999, the net capitalized costs  did
not  exceed the estimated present value of oil and gas reserves.  A  return
to  the oil price environment experienced during the first two quarters  of
1999  would have an adverse affect on the Company's revenues and  operating
cash flow.  Also, further declines in oil prices could result in additional
decreases in the carrying value of the Company's oil and gas properties.

A.  General Comparison of the Quarters Ended September 30, 1999 and 1998

The  following  table  provides certain information  regarding  performance
factors for the quarters ended September 30, 1999 and 1998:

Revenues

The  Partnership's oil and gas revenues increased to $127,204 from  $46,968
for  the  quarters  ended  September 30, 1999 and  1998,  respectively,  an
increase  of 171%.  The principal factors affecting the comparison  of  the
quarters ended September 30, 1999 and 1998 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the quarter ended September 30, 1999 as  compared  to
    the  quarter  ended  September 30, 1998 by 45%, or  $5.55  per  barrel,
    resulting  in  an increase of approximately $17,200 in  revenues.   Oil
    sales  represented  88% of total oil and gas sales during  the  quarter
    ended  September 30, 1999 as compared to 82% during the  quarter  ended
    September 30, 1998.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 3%, or $.05 per mcf, resulting  in
    an increase of approximately $200 in revenues.

    The  total  increase in revenues due to the change in  prices  received
    from oil and gas production is approximately $17,400.  The market price
    for  oil  and gas has been extremely volatile over the past decade  and
    management  expects a certain amount of volatility to continue  in  the
    foreseeable future.

<PAGE>

2.    Oil  production increased approximately 3,120 barrels or 101%  during
    the  quarter ended September 30, 1999 as compared to the quarter  ended
    September  30, 1998, resulting in an increase of approximately  $56,200
    in revenues.

    Gas production increased approximately 3,700 mcf or 77% during the same
    period, resulting in an increase of approximately $6,600 in revenues.

    The  total  increase  in revenues due to the change  in  production  is
    approximately $62,800. The sharp increase in oil and gas production  is
    in  relation  to  a  settlement of royalty on the  Dagger  Draw  Lease.
    Production  interest of approximately 5,000 bbls and  7,230  mcfs  were
    held  in  suspense from 1993 through 1999.  These dollars were received
    and recorded in Partnership during the third quarter of 1999.

Costs and Expenses

Total costs and expenses decreased to $36,724 from $43,516 for the quarters
ended  September 30, 1999 and 1998, respectively, a decrease of  16%.   The
decrease  is  the  result of lower lease operating costs  and  general  and
administrative  expense,  partially offset  by  an  increase  in  depletion
expense.

1.    Lease  operating  costs  and production  taxes  were  24%  lower,  or
   approximately $7,800 less during the quarter ended September 30, 1999 as
   compared  to the quarter ended September 30, 1998. The decline in  lease
   operating  costs  is  primarily in relation to the drop  in  oil  prices
   experienced throughout 1998 and into the first six months of 1999, which
   made  it  uneconomical to perform workovers and major repairs.  Although
   prices  have  increased during the third quarter of 1999,  only  routine
   repairs and maintenance for the most part are being performed.

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
    27% or approximately $1,400 during the quarter ended September 30, 1999
    as  compared  to the quarter ended September 30, 1998. The decrease  of
    general  and  administrative  costs were  in  part  due  to  additional
    accounting costs incurred in 1998 in relation to the outsourcing of K-1
    tax  package preparation; a change in auditors requiring opinions  from
    both  the  predecessors and successor auditors  and  a  new  accounting
    pronouncement requiring review by the independent auditors of  the  10-
    Q's.   The Managing General Partner has also made an effort to cut back
    on general and administrative costs whenever and wherever possible.

3.  Depletion  expense increased to $8,400 for the quarter ended  September
    30,  1999 from $6,000 for the same period in 1998.  This represents  an
    increase  of 40%.  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.   Contributing
    factors  to  the increase in depletion expense between the  comparative
    periods was the increase in the price of oil and gas used to value  the
    reserve  at  October  1, 1999 and the increase in  gross  oil  and  gas
    revenues.

B.   General Comparison of the Nine Month Periods Ended September 30,  1999
and 1998

The  following  table  provides certain information  regarding  performance
factors for the nine month periods ended September 30, 1999 and 1998:

                                                 Nine Months
                                                    Ended        Percentage
                                                September 30,     Increase
                                                1999      1998   (Decrease)
                                                ----      ----   ---------
Average price per barrel of oil            $   16.03     13.19      22%
Average price per mcf of gas               $    1.68      1.66       1%
Oil production in barrels                     11,400     8,800      30%
Gas production in mcf                         17,200    14,100      22%
Gross oil and gas revenue                  $ 211,648   139,584      52%

Partnership distributions                  $  45,000    31,500      43%
Investor partner distributions             $  40,050    28,035      43%
Per unit distribution to investor partners $   34.99     24.50      43%
Number of investor partner units             1,144.5   1,144.5

Revenues

The  Partnership's oil and gas revenues increased to $211,648 from $139,584
for  the  nine  months ended September 30, 1999 and 1998, respectively,  an
increase  of  52%.  The principal factors affecting the comparison  of  the
nine months ended September 30, 1999 and 1998 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the nine months ended September 30, 1999 as  compared
    to  the  nine  months ended September 30, 1998 by  22%,  or  $2.84  per
    barrel,  resulting in an increase of approximately $25,000 in revenues.
    Oil  sales represented 86% of total oil and gas sales during  the  nine
    months  ended  September 30, 1999 as compared to 83%  during  the  nine
    months ended September 30, 1998.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 1%, or $.02 per mcf, resulting  in
    an increase of approximately $300 in revenues.

    The  total  increase in revenues due to the change in  prices  received
    from oil and gas production is approximately $25,300.  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 2,600 barrels or 30% during the
    nine  months  ended September 30, 1999 as compared to the  nine  months
    ended  September  30, 1998, resulting in an increase  of  approximately
    $41,700 in revenues.

    Gas production increased approximately 3,100 mcf or 22% during the same
    period, resulting in an increase of approximately $5,200 in revenues.

    The  total  increase  in revenues due to the change  in  production  is
    approximately $46,900. The sharp increase in oil and gas production  is
    in  relation  to  a  settlement of royalty on the  Dagger  Draw  Lease.
    Production  interest of approximately 5,000 bbls and  7,230  mcfs  were
    held  in  suspense from 1993 through 1999.  These dollars were received
    and recorded in Partnership during the third quarter of 1999.

Costs and Expenses

Total  costs and expenses decreased to $92,319 from $132,582 for  the  nine
months ended September 30, 1999 and 1998, respectively, a decrease of  30%.
The  decrease  is  the result of lower lease operating costs,  general  and
administrative expense and depletion expense.

1. Lease   operating  costs  and  production  taxes  were  27%  lower,   or
   approximately  $22,500 less during the nine months ended  September  30,
   1999  as  compared  to  the nine months ended September  30,  1998.  The
   decline  in lease operating costs is primarily in relation to  the  drop
   in  oil prices experienced throughout 1998 and into the first six months
   of  1999,  which  made  it uneconomical to perform workovers  and  major
   repairs.   Although prices have increased during the  third  quarter  of
   1999,  only routine repairs and maintenance for the most part are  being
   performed.

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
    38%  or approximately $7,800 during the nine months ended September 30,
    1999  as  compared  to the nine months ended September  30,  1998.  The
    decrease  of  general  and administrative costs were  in  part  due  to
    additional  accounting  costs incurred  in  1998  in  relation  to  the
    outsourcing  of  K-1  tax package preparation;  a  change  in  auditors
    requiring  opinions  from both the predecessors and successor  auditors
    and  a new accounting pronouncement requiring review by the independent
    auditors of the 10-Q's.  The Managing General Partner has also made  an
    effort  to  cut back on general and administrative costs  whenever  and
    wherever possible.

3.  Depletion  expense  decreased to $20,000  for  the  nine  months  ended
    September  30,  1999 from $30,000 for the same period  in  1998.   This
    represents a decrease of 33%.  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.
    Contributing  factors to the decline in depletion expense  between  the
    comparative periods were the increase in the price of oil and gas  used
    to determine the Partnership's reserves for October 1, 1999 as compared
    to 1998.

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 $130,000  in
the  nine  months  ended  September 30, 1999 as compared  to  approximately
$55,700 in the nine months ended September 30, 1998.  The primary source of
the 1999 cash flow from operating activities was profitable operations.

Cash flows used in investing activities were approximately $800 in the nine
months ended September 30, 1999 as compared to approximately $21,800 in the
nine  months ended September 30, 1998.  The principle use of the 1999  cash
flow from investing activities was the change in oil and gas properties.

Cash  flows used in financing activities were approximately $47,800 in  the
nine  months ended September 30, 1999 as compared to approximately  $29,400
in  the  nine  months ended September 30, 1998.  The only use in  financing
activities was the distributions to partners.

Total  distributions during the nine months ended September 30,  1999  were
$45,000  of  which  $40,050 was distributed to the  investor  partners  and
$4,950  to  the  Managing General Partner.  The per  unit  distribution  to
investor  partners  during the nine months ended  September  30,  1999  was
$34.99.   Total  distributions during the nine months ended  September  30,
1998 were $31,500 of which $28,035 was distributed to the investor partners
and  $3,465 to the Managing General Partner.  The per unit distribution  to
investor  partners  during the nine months ended  September  30,  1998  was
$24.50.

The source for the 1999 distributions of $45,000 was oil and gas operations
of  approximately  $130,000 and the change in oil  and  gas  properties  of
approximately   $800,  resulting  in  excess  cash  for  contingencies   or
subsequent distributions.  The source for the 1998 distributions of $31,500
was  oil and gas operations of approximately $55,700, and the change in oil
and  gas properties of approximately $21,800, resulting in excess cash  for
contingencies or subsequent distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $1,172,740 have been made to the partners.  As of September  30,  1999,
$1,045,650 or $913.63 per investor partner unit has been distributed to the
investor partners, representing an 91% return of the capital contributed.

As  of  September 30, 1999, the Partnership had approximately  $102,400  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  $21.0 million of interest payments due within the next twelve  months
on  its  debt obligations.  Due to the severely depressed commodity  prices
experienced for the past eighteen monhts, 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  Managing  General Partner provides all data processing  needs  of  the
Partnership.  The Managing General Partner has identified and assessed  its
exposure  to the potential Year 2000 software and imbedded chip  processing
and  date  sensitivity issue.  Through the Managing General  Partners  data
processing  subsidiary,  Midland Southwest  Software,  Inc.,  the  Managing
General   Partner  proactively  initiated  an  internal  plan  to  identify
applicable hardware and software, assess impact and effect, estimate costs,
construct and implement corrective actions, and prepare contingency plans.

Identification & Assessment
The  Managing General Partner currently believes it identified the internal
and  external  software  and  hardware that  had  the  potential  for  date
sensitivity   problems.   Four  critical  systems  and/or  functions   were
identified  and addressed:  (1) the proprietary software of the Partnership
(OGAS)  that  is  used  for  oil & gas property  management  and  financial
accounting  functions, (2) the DEC VAX/VMS hardware and  operating  system,
(3)  various  third-party  application software  including  lease  economic
analysis,   fixed   asset   management,   geological   applications,    and
payroll/human resource programs, and (4) External Agents.

The   proprietary   software  of  the  Partnership   has   met   compliance
requirements.  Since this is an internally generated software package,  the
Managing  General  Partner  incurred approximately  $25,000  in  man-hours.
Modifications were made by internal staff and did not represent  additional
costs  to  the  Partnership.  The Managing General  Partner  has  not  made
contingency  plans at this time since the conversion is ahead  of  schedule
and   being  handled  by  Managing  General  Partner  controlled   internal
programmers.  Given the complexity of the systems that were modified, it is
anticipated  that  some  problems  may arise,  but  having  met  the  early
completion  date,  the Managing General Partner feels  that  adequate  time
remains available to overcome unforeseen delays.




<PAGE>
DEC has released a fully compliant version of its operating system that  is
used  by  the  Partnership on the DEC VAX system.  It  was  installed,  the
Managing  General Partner believes that this solved any potential  problems
on the system.

The  Managing  General Partner has identified various third-party  software
that may have date sensitivity problems and is continuing to work with  the
vendors  to  secure solutions as well as prepare contingency plans.   After
review  and evaluation of the vendor plans and status, the Managing General
Partner believes that the problems will be resolved prior to the year  2000
or   the  alternate  contingency  plan  will  sufficiently  and  adequately
remediate  the problem so that there is no material disruption to  business
functions.

The  External  Agents  of  the  Partnership include  suppliers,  customers,
owners,  vendors, banks, product purchasers including pipelines, and  other
oil  and  gas property operators.  The Managing General Partner is  in  the
process of identifying and communicating with each critical External  Agent
about  its  plan  and progress thereof in addressing the Year  2000  issue.
This process is on schedule and the Managing General Partner, at this time,
believes  that  there  should  be no material  interference  or  disruption
associated with any of the critical External Agent's functions necessary to
the   Partnership's  business.   The  Managing  General  Partner  estimates
completion of this audit by year end 1999 and believes that alternate plans
can  be  devised to circumvent any material problems arising from  critical
External Agent noncompliance.

Cost
To  date,  the Managing General Partner has incurred only minimal  internal
man-hour costs for identification, planning, and maintenance.  The Managing
General  Partner believes that the necessary additional costs will also  be
minimal  and most will fall under normal and general maintenance procedures
and updates.  An accurate cost cannot be determined at this time, but it is
expected  that  the total cost to remediate all systems  to  be  less  than
$50,000.

Risks/Contingency
The  failure to correct critical systems of the Partnership, or the failure
of  a  material business partner or External Agent to resolve critical Year
2000  issues  could  have a serious adverse impact on the  ability  of  the
Partnership  to  continue operations and meet obligations.   Based  on  the
Managing  General  Partner's  evaluation and  assessment  to  date,  it  is
believed  that any interruption in operation will be minor and  short-lived
and  pose no material monetary loss, safety, or environmental risk  to  the
Partnership.   However,  due  to  the  external  nature  of  the  potential
problems,  it  is  impossible to accurately identify  the  risks,  quantify
potential  impacts  or  establish a final contingency  plan.  The  Managing
General Partner believes that its assessment and contingency planning  will
be complete no later than year-end 1999.

Worst Case Scenario
The  Securities  and  Exchange  Commission  requires  public  companies  to
forecast the most reasonably likely worst case Year 2000 scenario, assuming
that  the  Managing  General Partner's Year 2000  plan  is  not  effective.
Analysis  of the most reasonably likely worst case Year 2000 scenarios  the
Partnership  may face leads to contemplation of the following possibilities
which,  though  considered  highly  unlikely,  must  be  included  in   any
consideration  of worst cases: widespread failure of electrical,  gas,  and
similar   supplies   by  utilities  serving  the  Partnership;   widespread
disruption  of  the  services of communications  common  carriers;  similar
disruption to means and modes of transportation for the Partnership and its
employees, contractors, suppliers, and customers; significant disruption to
the  Partnership's  ability to gain access to,  and  continue  working  in,
office  buildings  and other facilities; and the failure, of  third-parties
systems,  the  effects  of which would have a cumulative  material  adverse
impact  on  the  Partnership's  critical systems.   The  Partnership  could
experience  an inability by customers, traders, and others  to  pay,  on  a
timely  basis or at all, obligations owed to the Partnership.  Under  these
circumstances, the adverse effect on the Partnership, and the diminution of
Partnership revenues, could be material, although not quantifiable at  this
time.
