limited  partnership interests began October 25, 1993, as part of  a  shelf
offering registered under the name Southwest Royalties Institutional  1992-
93  Income Program.  Minimum capital requirements for the Partnership  were
met on December 8, 1993, with the offering of limited partnership interests
concluding  August  20, 1994, with total limited partner  contributions  of
$2,425,500.

The Partnership was formed to acquire royalty and net profits 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 will not be  reinvested  in  other
revenue producing assets except to the extent that producing facilities and
wells are reworked or where methods are employed to improve or enable  more
efficient  recovery  of oil and gas reserves.  The  economic  life  of  the
Partnership will thus depend on the period over which the Partnership's oil
and gas reserves are economically recoverable.

Increases   or   decreases   in  Partnership   revenues   and,   therefore,
distributions  to partners will depend primarily on changes in  the  prices
received  for  production,  changes in volumes of  production  sold,  lease
operating  expenses, enhanced recovery projects, offset drilling activities
pursuant  to farm-out arrangements, 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 does not  anticipate  performing
workovers  during  the year.  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. The Partnership's capitalized costs did  not  exceed  the
estimated present value of reserves as of June 30, 2000.

A.  General Comparison of the Quarters Ended June 30, 2000 and 1999

The  following  table  provides certain information  regarding  performance
factors for the quarters ended June 30, 2000 and 1999:

Revenues

The  Partnership's income from net profits interests increased  to  $75,605
from  $33,792  for the quarters ended June 30, 2000 and 1999, respectively,
an increase of 124%.  The principal factors affecting the comparison of the
quarters ended June 30, 2000 and 1999 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the quarter ended June 30, 2000 as  compared  to  the
    quarter ended June 30, 1999 by 79%, or $12.50 per barrel, resulting  in
    an  increase  of  approximately $25,000  in  income  from  net  profits
    interests.  Oil sales represented 38% of total oil and gas sales during
    the  quarter ended June 30, 2000 as compared to 43% during the  quarter
    ended June 30, 1999.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 119%, or $2.36 per mcf,  resulting
    in  an  increase  of approximately $49,100 in income from  net  profits
    interests.

    The  total  increase in income from net profits interests  due  to  the
    change  in prices received from oil and gas production is approximately
    $74,100.   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.


2.  Oil  production decreased approximately 400 barrels or 20%  during  the
    quarter  ended June 30, 2000 as compared to the quarter ended June  30,
    1999,  resulting in a decrease of approximately $11,400 in income  from
    net profits interests.

    Gas production decreased approximately 3,500 mcf or 17% during the same
    period, resulting in a decrease of approximately $15,200 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production  is  approximately  $26,600.   The  decrease  in
    production  is primarily due to the occurrence of payout on the  Dagger
    Draw,  upon  occurrence of payout the percentage of ownership  for  the
    Partnership decreased significantly.

3.  Lease  operating  costs  and  production  taxes  were  17%  higher,  or
    approximately  $6,800 more during the quarter ended June  30,  2000  as
    compared  to  the  quarter ended June 30, 1999. The increase  in  lease
    operating  costs  and production taxes is primarily  a  result  of  the
    higher  oil and gas prices received by the Partnership.  Higher  prices
    have  made  it  possible for the Partnership to  perform  needed  major
    repairs  and  maintenance.  Since production taxes are based  on  gross
    revenues,  the  increase in oil and gas prices have directly  increased
    production taxes.

Costs and Expenses

Total costs and expenses decreased to $11,985 from $18,770 for the quarters
ended  June  30,  2000  and 1999, respectively, a  decrease  of  36%.   The
decrease  is  the  result  of  lower  depletion  expense  and  general  and
administrative expense.

1.  General and administrative costs consists of independent accounting and
    engineering  fees,  computer services, postage,  and  Managing  General
    Partner personnel costs.  General and administrative costs decreased 7%
    or  approximately  $800  during the quarter  ended  June  30,  2000  as
    compared to the quarter ended June 30, 1999.

2.    Depletion expense decreased to $2,000 for the quarter ended June  30,
   2000 from $8,000 for the same period in 1999.  This represents a decrease
   of  75%.   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 July
   1, 2000 as compared to 1999.

3. The  Partnership entered into a purchase agreement on the  Kaiser  State
   lease  that guaranteed net income each month for a specified  period  of
   time.    This  income  was  recorded  on  the  Partnerships   books   as
   miscellaneous income.  This property was later sold.



B.  General  Comparison of the Six Month Periods Ended June  30,  2000  and
    1999

The  following  table  provides certain information  regarding  performance
factors for the six month periods ended June 30, 2000 and 1999:

                                                Six Months
                                                  Ended          Percentage

                                              2000       1999    (Decrease)
                                              ----       ----    ----------
Average price per barrel of oil         $     27.90     12.87      117%
Average price per mcf of gas            $      3.78      1.79      111%
Oil production in barrels                     3,600     4,300     (16%)
Gas production in mcf                        36,400    39,100      (7%)
Income from net profits interests       $   146,758    48,533      202%
Partnership distributions               $   110,000    25,699      328%
Limited partner distributions           $    99,000    23,299      325%
Per unit distribution to limited
 partners                               $     20.41      4.80      325%
Number of limited partner units               4,851     4,851

Revenues

The  Partnership's income from net profits interests increased to  $146,758
from $48,533 for the six months ended June 30, 2000 and 1999, respectively,
an increase of 202%.  The principal factors affecting the comparison of the
six months ended June 30, 2000 and 1999 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased during the six months ended June 30, 2000 as compared to  the
    six months ended June 30, 1999 by 117%, or $15.03 per barrel, resulting
    in  an  increase  of approximately $64,600 in income from  net  profits
    interests.  Oil sales represented 42% of total oil and gas sales during
    the  six  months ended June 30, 2000 as compared to 44% during the  six
    months ended June 30, 1999.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 111%, or $1.99 per mcf,  resulting
    in  an  increase  of approximately $77,800 in income from  net  profits
    interests.

    The  total  increase in income from net profits interests  due  to  the
    change  in prices received from oil and gas production is approximately
    $142,400.  The market price for oil and gas has been extremely volatile
    over  the  past  decade, and management expects  a  certain  amount  of
    volatility to continue in the foreseeable future.


2.  Oil  production decreased approximately 700 barrels or 16%  during  the
    six months ended June 30, 2000 as compared to the six months ended June
    30,  1999,  resulting in a decrease of approximately $19,500 in  income
    from net profits interests.

    Gas  production decreased approximately 2,700 mcf or 7% during the same
    period, resulting in a decrease of approximately $10,200 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production  is  approximately  $29,700.  The  decrease   in
    production  is primarily due to the occurrence of payout on the  Dagger
    Draw,  upon  occurrence of payout the percentage of ownership  for  the
    Partnership decreased significantly.

3.  Lease  operating  costs  and  production  taxes  were  18%  higher,  or
    approximately $14,200 more during the six months ended June 30, 2000 as
    compared  to the six months ended June 30, 1999. The increase in  lease
    operating  costs  and production taxes is primarily  a  result  of  the
    higher  oil and gas prices received by the Partnership.  Higher  prices
    have  made  it  possible for the Partnership to  perform  needed  major
    repairs  and  maintenance.  Since production taxes are based  on  gross
    revenues,  the  increase in oil and gas prices have directly  increased
    production taxes.

Costs and Expenses

Total  costs  and expenses decreased to $33,004 from $43,586  for  the  six
months ended June 30, 2000 and 1999, respectively, a decrease of 24%.   The
decrease  is  the  result of lower general and administrative  expense  and
miscellaneous expense.

1.  General and administrative costs consists of independent accounting and
    engineering  fees,  computer services, postage,  and  Managing  General
    Partner  personnel costs.  General and administrative  costs  decreased
    11%  or approximately $2,500 during the six months ended June 30,  2000
    as compared to the six months ended June 30, 1999.

2.    Depletion expense decreased to $13,000 for the six months ended  June
   30,  2000  from $21,000 for the same period in 1999.  This represents  a
   decrease of 38%.  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 July
   1, 2000 as compared to 1999.

3. The  Partnership entered into a purchase agreement on the  Kaiser  State
   lease  that guaranteed net income each month for a specified  period  of
   time.    This  income  was  recorded  on  the  Partnerships   books   as
   miscellaneous income.  This property was later sold.



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 $115,500  in
the six months ended June 30, 2000 as compared to approximately $34,600  in
the  six  months ended June 30, 1999.  The primary source of the 2000  cash
flow from operating activities was profitable operations.

There  were no investing activities in the six months ended June 30,  2000.
Cash flows provided by investing activities were approximately $800 in  the
six months ended June 30, 1999.

Cash flows used in financing activities were approximately $109,900 in  the
six  months ended June 30, 2000 as compared to approximately $25,800 in the
six  months  ended June 30, 1999. The only use in financing activities  was
the distributions to partners.

Total distributions during the six months ended June 30, 2000 were $110,000
of which $99,000 was distributed to the limited partners and $11,000 to the
general partners.  The per unit distribution to limited partners during the
six  months ended June 30, 2000 was $20.41. Total distributions during  the
six  months  ended  June  30,  1999  were  $25,699  of  which  $23,299  was
distributed  to  the limited partners and $2,400 to the  general  partners.
The  per unit distribution to limited partners during the six months  ended
June 30, 1999 was $4.80.

The  source  for  the  2000  distributions of  $110,000  was  oil  and  gas
operations   of   approximately  $115,500.   The  source   for   the   1999
distributions  of  $25,699  was  oil and gas  operations  of  approximately
$34,600 and the net change in oil and gas properties of approximately $800,
resulting in excess cash for contingencies or subsequent distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $1,212,138  have  been made to the partners.   As  of  June  30,  2000,
$1,104,952 or $227.78 per limited partner unit has been distributed to  the
limited partners, representing a 45% return of the capital contributed.

As  of  June 30, 2000, the Partnership had approximately $82,500 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  $50.1  million principal due by December 31, 2000 and  $15.3  million
interest   payments  due  within  the  next  twelve  months  on  its   debt
obligations.  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.
