concluding April 30, 1992, with 340 limited partners purchasing 5,983 units
for $2,991,500.

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  the  net
proceeds from operations to the limited and general partners.  Net revenues
from  producing  oil  and gas properties will not be  reinvested  in  other
revenue  producing  assets except to the extent that production  facilities
and wells are improved or reworked or where methods are employed to improve
or enable more efficient recovery of oil and gas reserves.

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 farmout 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 next twelve months.  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, 2000, the net capitalized costs  did
not exceed the estimated present value of oil and gas reserves.

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

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

Revenues

The  Partnership's income from net profits interests increased to  $112,639
from   $72,607  for  the  quarters  ended  September  30,  2000  and  1999,
respectively,  an  increase of 55%.  The principal  factors  affecting  the
comparison  of  the  quarters ended September 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 September 30, 2000 as compared  to
     the  quarter ended September 30, 1999 by %, 55%, or $10.39 per barrel,
     resulting in an increase of approximately $90,800 in income  from  net
     profits  interests.  Oil sales represented 85% of total  oil  and  gas
     sales  during the quarter ended September 30, 2000 as compared to  86%
     during the quarter ended September 30, 1999.

     The  average  price  for  an mcf of gas received  by  the  Partnership
     increased  during the same period by 111%, or $2.24 per mcf, resulting
     in  an  increase of approximately $28,800 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
     $119,600.   The  market  price  for oil and  gas  has  been  extremely
     volatile over the past decade, and management expects a certain amount
     of volatility to continue in the foreseeable future.

<PAGE>

2. Oil  production decreased approximately 1,140 barrels or 13% during  the
   quarter  ended  September  30, 2000 as compared  to  the  quarter  ended
   September 30, 1999, resulting in a decrease of approximately $33,200  in
   income from net profits interests.

    Gas production decreased approximately 3,760 mcf or 29% during the same
    period, resulting in a decrease of approximately $16,000 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production is approximately $49,200.  The decrease  in  gas
    production  is primarily due to a non-operated gas well.  The  operator
    performed  a  workover during the last quarter of 1999, which  was  not
    only  unsuccessful, but caused the well to shut down.  The well is  not
    believed  to  be  recoverable, thus the  loss  to  the  Partnership  is
    considered to be permanent.  This well represented approximately  1,220
    mcf a month to the Partnership.

3.  Lease  operating  costs  and  production  taxes  were  21%  higher,  or
    approximately $24,100 more during the quarter ended September 30,  2000
    as  compared  to the quarter ended September 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 increased to $20,265 from $9,935 for the quarters
ended September 30, 2000 and 1999, respectively, an increase of 104%.   The
increase  is  the  result  of  higher 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 increased 3%
    or  approximately $300 during the quarter ended September 30,  2000  as
    compared to the quarter ended September 30, 1999.

2.  Depletion  expense  increased to $10,000  for  the  nine  months  ended
    September  30,  2000. There was no depletion expense recorded  for  the
    quarter ended September 30, 1999.  This represents an increase of 100%.
    Depletion   is  calculated  using  the  units  of  revenue  method   of
    amortization based on a percentage of current period gross revenues  to
    total  future  gross  oil  and  gas  revenues,  as  estimated  by   the
    Partnership's  independent  petroleum  consultants.  The  increase   in
    depletion  expense  is  due to an accrual adjustment,  which  was  made
    during  the  quarter ended September 30, 1999 to adjust  for  the  over
    accrual of depletion in the first two quarters of 1999.  The rapid rise
    in  prices  during  the first three quarters of 1999  from  $14/bbl  to
    $23/bbl  and  from  $1.71/mcf to $2.38/mcf caused an adjustment  to  be
    necessary during the third quarter of 1999.

B.   General Comparison of the Nine Month Periods Ended September 30,  2000
and 1999

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

                                                 Nine Months
                                                    Ended        Percentage

                                                ----      ----   ---------
Average price per barrel of oil            $   27.26     14.50     88%
Average price per mcf of gas               $    3.58      2.02     77%
Oil production in barrels                     23,000    26,340   (13%)
Gas production in mcf                         20,740    38,410   (46%)
Income from net profits interests          $ 273,888    83,782    227%
Partnership distributions                  $ 190,000    24,277    683%
Limited partner distributions              $ 171,000    23,477    628%
Per unit distribution to limited partners  $   28.58      3.92    628%
Number of limited partner units                5,983     5,983

Revenues

The  Partnership's income from net profits interests increased to  $273,888
from  $83,782  for  the  nine months ended September  30,  2000  and  1999,
respectively,  an  increase of 227%.  The principal factors  affecting  the
comparison  of  the nine months ended September 30, 2000 and  1999  are  as
follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    increased  during the nine months ended September 30, 2000 as  compared
    to  the  nine  months ended September 30, 1999 by 88%,  or  $12.76  per
    barrel,  resulting in an increase of approximately $336,100  in  income
    from net profits interests.  Oil sales represented 89% of total oil and
    gas  sales during the nine months ended September 30, 2000 as  compared
    to 83% during the nine months ended September 30, 1999.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased during the same period by 77%, or $1.56 per mcf, resulting in
    an  increase  of  approximately $59,900  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
    $396,000.  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 3,340 barrels or 13% during the
    nine  months  ended September 30, 2000 as compared to the  nine  months
    ended  September  30,  1999, resulting in a decrease  of  approximately
    $91,000 in income from net profits interests.

    Gas  production  decreased approximately 17,670 mcf or 46%  during  the
    same period, resulting in a decrease of approximately $63,300 in income
    from net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change  in  production  is  approximately $154,300.  The  Partnership's
    dramatic decline in gas production was primarily in connection with two
    wells.  During 1999, the Partnership was involved in a lawsuit in order
    to  receive payment for two months of production from the purchaser  at
    that  time.   The  lawsuit was settled in the  current  year  with  the
    Partnership  receiving  less than was owed  from  the  purchaser.   The
    original  accrual  recorded  during the  second  quarter  of  1999  was
    reversed  in the current year.  This reversal represented approximately
    2,800  mcf.   Additionally, the partnership  was  informed  during  the
    current  year  that  a  workover which was performed  during  the  last
    quarter  of  1999 on a non-operated well was not only unsuccessful  but
    caused  the  well  to  shut down.  This well  is  not  believed  to  be
    recoverable,  thus  the loss to the Partnership  is  considered  to  be
    permanent.   This  well represented approximately 1,220  mcf  a  month.
    Total  decline  for  the  partnership  during  the  nine  months  ended
    September  30,  2000  in  connection with this  non-operated  well  was
    approximately 14,850 mcf.

3.  Lease  operating  costs  and  production  taxes  were  14%  higher,  or
    approximately  $51,300 more during the nine months ended September  30,
    2000  as  compared  to the nine months ended September  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 $55,858 from $62,232 for  the  nine
months ended September 30, 2000 and 1999, respectively, a decrease of  10%.
The  decrease is the result of lower general and administrative expense and
depletion 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 4%
    or approximately $1,400 during the nine months ended September 30, 2000
    as compared to the nine months ended September 30, 1999.

2.  Depletion  expense  decreased to $25,000  for  the  nine  months  ended
    September  30,  2000 from $30,000 for the same period  in  1999.   This
    represents a decrease of 17%.  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 and the increase in oil and gas
    revenues received by the Partnerships.

<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 $248,500  in
the  nine  months  ended  September 30, 2000 as compared  to  approximately
$17,800 in the nine months ended September 30, 1999.  The primary source of
the 2000 cash flow from operating activities was profitable operations.

Cash  flows  (used in) provided by investing activities were  approximately
$(5)  in  the  nine  months  ended  September  30,  2000  as  compared   to
approximately $18,800 in the nine months ended September 30, 1999.

Cash flows used in financing activities were approximately $190,000 in  the
nine  months ended September 30, 2000 as compared to approximately  $24,300
in  the  nine  months ended September 30, 1999.  The only use in  financing
activities was the distributions to partners.

Total  distributions during the nine months ended September 30,  2000  were
$190,000  of  which  $171,000 was distributed to the limited  partners  and
$19,000  to  the  general partners.  The per unit distribution  to  limited
partners during the nine months ended September 30, 2000 was $28.58.  Total
distributions during the nine months ended September 30, 1999 were  $24,277
of  which $23,477 was distributed to the limited partners and $800  to  the
general partners.  The per unit distribution to limited partners during the
nine months ended September 30, 1999 was $3.92.

The  sources  for  the  2000 distributions of $190,000  were  oil  and  gas
operations  of  approximately  $248,500,  resulting  in  excess  cash   for
contingencies  or  subsequent  distributions.   The  source  for  the  1999
distributions  of  $24,277  was  oil and gas  operations  of  approximately
$17,800  and  a  change  in oil and gas property of approximately  $18,800,
resulting in excess cash for contingencies or subsequent distributions.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $2,837,245 have been made to the partners.  As of September  30,  2000,
$2,567,005 or $429.05 per limited partner unit has been distributed to  the
limited partners, representing a 86% return of the capital contributed.

As  of  September 30, 2000, the Partnership had approximately  $190,300  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.


<PAGE>
Liquidity - Managing General Partner
The  Managing General Partner has a highly leveraged capital structure with
approximately, $33.8 million of cash interest and $5.9 million of principal
due  within  the  next  twelve  months.  The Managing  General  Partner  is
currently  in  the  process  of renegotiating  the  terms  of  its  various
obligations with its note holders 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  continuing
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.
