30,  1993.   At  the  conclusion  of the offering  of  limited  partnership
interests, 122 limited partners had purchased 2,821 units for $1,410,500.

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 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  anticipates  performing   some
workovers during the year.

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  cost  did  not  exceed
estimated present value of reserves as of June 30, 2000.

Results of Operations

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 oil and gas revenues increased to $74,641  from  $50,256
for the quarters ended June 30, 2000 and 1999, respectively, an increase of
49%.   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 76%, or $11.29 per barrel, resulting  in
    an   increase  of  approximately  $15,500  in  revenues.    Oil   sales
    represented  42%  of total oil and gas sales during the  quarter  ended
    June  30,  2000  as compared to 40% 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 98%, or $1.97 per mcf, resulting in
    an increase of approximately $29,400 in revenues.

    The  total  increase in revenues due to the change in  prices  received
    from oil and gas production is approximately $44,900.  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 170 barrels or 12%  during  the
    quarter  ended June 30, 2000 as compared to the quarter ended June  30,
    1999, resulting in a decrease of approximately $4,400 in revenues.

    Gas production decreased approximately 4,000 mcf or 27% during the same
    period, resulting in a decrease of approximately $15,900 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $20,300.  The decrease in production is due primarily  to
    sharp natural decline on one major gas lease.  Production on this lease
    fluctuates.

Costs and Expenses

Total costs and expenses increased to $57,956 from $40,208 for the quarters
ended  June  30,  2000  and 1999, respectively, an increase  of  44%.   The
increase is the result of higher lease operating costs, partially offset by
a decrease in general and administrative expense and depletion expense.

1.  Lease  operating  costs  and  production  taxes  were  92%  higher,  or
    approximately $24,700 more during the quarter ended June  30,  2000  as
    compared to the quarter ended June 30, 1999.  The dramatic increase  in
    lease  operating  costs  are the result of costs  associated  with  the
    drilling of an injection well.

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
    18%  or  approximately $900 during the quarter ended June 30,  2000  as
    compared  to the quarter ended June 30, 1999.  The decrease in  general
    and  administrative costs is primarily due to a decrease in  management
    fees charged by the managing general partner.

3.  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.

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

Oil production in barrels                     2,200     2,670     (18%)
Gas production in mcf                        24,000    28,000     (14%)
Gross oil and gas revenue                $  136,028    84,179       62%
Net oil and gas revenue                  $   66,038    30,492      117%
Partnership distributions                $   30,000    54,407     (45%)
Limited partner distributions            $   27,000    51,407     (47%)
Per unit distribution to limited
 partners                                $     9.57     18.22     (47%)
Number of limited partner units               2,821     2,821

Revenues

The  Partnership's oil and gas revenues increased to $136,028 from  $84,179
for  the six months ended June 30, 2000 and 1999, respectively, an increase
of  62%.  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 113%, or $13.62 per barrel, resulting
    in  an  increase  of  approximately $36,400  in  revenues.   Oil  sales
    represented 42% of total oil and gas sales during the six months  ended
    June  30, 2000 as compared to 38% 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 78%, or $1.45 per mcf, resulting in
    an increase of approximately $40,600 in revenues.

    The  total  increase in revenues due to the change in  prices  received
    from oil and gas production is approximately $77,000.  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 470 barrels or 18%  during  the
    six months ended June 30, 2000 as compared to the six months ended June
    30, 1999, resulting in a decrease of approximately $12,100 in revenues.

    Gas production decreased approximately 4,000 mcf or 14% during the same
    period, resulting in a decrease of approximately $13,200 in revenues.

    The  total  decrease  in revenues due to the change  in  production  is
    approximately $25,300.  The decrease in production is due primarily  to
    sharp natural decline on one major gas lease.  Production on this lease
    fluctuates.

Costs and Expenses

Total  costs  and expenses increased to $87,785 from $83,000  for  the  six
months ended June 30, 2000 and 1999, respectively, an increase of 6%.   The
increase is the result of higher lease operating costs, partially offset by
a decrease in general and administrative expense and depletion expense.

1.  Lease  operating  costs  and  production  taxes  were  30%  higher,  or
    approximately $16,300 more during the six months ended June 30, 2000 as
    compared  to the six months ended June 30, 1999. The dramatic  increase
    in  lease  operating costs are the result of costs associated with  the
    drilling of an injection well.

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
    29%  or approximately $3,500 during the six months ended June 30,  2000
    as  compared  to  the six months ended June 30, 1999. The  decrease  in
    general  and  administrative costs is primarily due to  a  decrease  in
    management fees charged by the managing general partner.

3.  Depletion expense decreased to $9,000 for the six months ended June 30,
    2000  from  $17,000  for the same period in 1999.   This  represents  a
    decrease  of 47%.  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.

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 $46,800  in
the six months ended June 30, 2000 as compared to approximately $31,000  in
the  six  months ended June 30, 1999.  The primary source of the 2000  cash
flow from operating activities was profitable operations.

Cash flows used in investing activities were approximately $600 in the  six
months  ended June 30, 2000 as compared to approximately $200  in  the  six
months  ended June 30, 1999.  The principle use of the 2000 cash flow  from
investing activities was the additions to oil and gas properties.

Cash  flows used in financing activities were approximately $30,000 in  the
six  months ended June 30, 2000 as compared to approximately $54,400 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 $30,000
of  which $27,000 was distributed to the limited partners and $3,000 to the
general partners.  The per unit distribution to limited partners during the
six  months ended June 30, 2000 was $9.57.  Total distributions during  the
six  months  ended  June  30,  1999  were  $54,407  of  which  $51,407  was
distributed  to  the limited partners and $3,000 to the  general  partners.
The  per unit distribution to limited partners during the six months  ended
June 30, 1999 was $18.22.

The  sources  for  the  2000  distributions of $30,000  were  oil  and  gas
operations  of  approximately  $46,800  and  the  change  in  oil  and  gas
properties   of  approximately  $(600),  resulting  in  excess   cash   for
contingencies  or  subsequent  distributions.   The  source  for  the  1999
distributions  of  $54,407  was  oil and gas  operations  of  approximately
$31,000,  and  less the change in oil and gas properties  of  approximately
$200, with the balance from available from cash on hand at the beginning of
the period.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $1,017,195  have  been made to the partners.   As  of  June  30,  2000,
$928,645  or $329.19 per limited partner unit has been distributed  to  the
limited partners, representing a 66% return of the capital contributed.

As  of  June 30, 2000, the Partnership had approximately $62,700 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
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.
