Item 2.     Management's Discussion and Analysis of Financial Condition
             and Results of Operations (1)

Results of Operations

Six months ended June 30, 2000 compared with six months ended June 30, 1999

Revenues:

The Partnership's  oil and gas revenues  increased 76% to $1,095,887 for the six
months  ended June 30, 2000 as compared to $621,001 for the same period in 1999.
The increase in revenues resulted from higher average prices received, offset by
a decrease in production. For the six months ended June 30, 2000, 25,927 barrels
of oil, 16,013 barrels of  natural gas  liquids  ("NGLs") and  70,252 mcf of gas

                                        7

were sold,  or 53,649  barrel of oil  equivalents  ("BOEs").  For the six months
ended June 30, 1999,  27,730  barrels of oil,  17,155 barrels of NGLs and 79,292
mcf of gas were sold, or 58,100 BOEs.

The average price  received per barrel of oil increased  $14.45,  or 108%,  from
$13.33 for the six months  ended June 30,  1999 to $27.78 for the same period in
2000.  The average price received per barrel of NGLs  increased  $6.16,  or 78%,
from  $7.94  during the six  months  ended June 30,  1999 to $14.10 for the same
period in 2000.  The average  price  received per mcf of gas  increased 47% from
$1.45  during the six months ended June 30, 1999 to $2.13 for the same period in
2000. The market price for oil and gas has been  extremely  volatile in the past
decade and  management expects a certain amount of volatility to continue in the
foreseeable  future.  The  Partnership may therefore sell its future oil and gas
production at average  prices lower or higher than that received  during the six
months ended June 30, 2000.

The volatility of commodity prices has had, and continues to have, a significant
impact on the Partnership's revenues and operating cash flow and could result in
additional  decreases to the  carrying  value of the  Partnership's  oil and gas
properties.

A gain on disposition  of assets of $5,351 was recognized  during the six months
ended June 30, 2000 from equipment credits received on a fully depleted well.

Costs and Expenses:

Total costs and expenses increased to $567,246 for the six months ended June 30,
2000 as compared to $558,526 for the same period in 1999, an increase of $8,720,
or 2%.  This  increase  resulted  from higher  production  costs and general and
administrative expenses ("G&A"), offset by a decline in depletion.

Production  costs  were  $480,127  for the six months  ended  June 30,  2000 and
$416,974 for the same period in 1999  resulting in a $63,153  increase,  or 15%.
The increase was the result of higher  production taxes due to increased oil and
gas  revenues  and  additional  well  maintenance  costs  incurred to  stimulate
production.

G&A's  components are independent  accounting and engineering  fees and managing
general  partner  personnel  and  operating  costs.   During  this  period,  G&A
increased, in aggregate, 63% from $21,326 for the six months ended June 30, 1999
to $34,788 for the same period in 2000  primarily  due to a higher allocation of
the managing general partner's G&A being allocated (limited to 3% of oil and gas
revenues) as a result of increased oil and gas revenues.

Depletion  was  $52,331  for the six months  ended  June 30,  2000  compared  to
$120,226  for the same  period in 1999,  a decrease  of  $67,895,  or 56%.  This
decrease was primarily  attributable  to an increase in proved  reserves for the
period  ended June 30,  2000 due to higher  commodity  prices,  a decline in oil
production  of 1,803  barrels for the six months ended June 30, 2000 compared to
the same  period in 1999 and a reduction  in the  Partnership's  net  depletable
basis from charges taken in accordance  with  Statement of Financial  Accounting
Standards No. 121,  "Accounting for the Impairment of Long-Lived  Assets and for
Long-Lived  Assets to be Disposed Of" ("SFAS 121") during the fourth  quarter of
1999.

Three months ended June 30, 2000 compared with three months ended June 30, 1999

Revenues:

The Partnership's  oil and gas revenues  increased 44% to $545,418 for the three
months  ended June 30, 2000 as compared to $379,880 for the same period in 1999.
The increase in revenues resulted from higher average prices received, offset by
a decrease in  production.  For the three  months  ended June 30,  2000,  12,194
barrels of oil, 7,964 barrels of NGLs and 34,873 mcf of gas were sold, or 25,970
BOEs. For the three months ended June 30, 1999,  13,447  barrels of oil,  10,998
barrels of NGLs and 46,749 mcf of gas were sold, or 32,237 BOEs.

The average  price  received per barrel of oil  increased  $12.86,  or 85%, from
$15.05 for the three  months  ended June 30, 1999 to $27.91 for the three months
ended June 30, 2000.  The average  price  received per barrel of NGLs  increased
$5.38,  or 58%, from $9.34 during the three months ended June 30, 1999 to $14.72
for the same period in 2000. The average price received per mcf of gas increased
58% from $1.60 during the three months ended June 30, 1999 to $2.52 for the same
period in 2000.

A gain on disposition of assets of $1,428 was recognized during the three months
ended June 30, 2000 from equipment credits received on a fully depleted well.

Costs and Expenses:

Total costs and  expenses  increased to $287,547 for the three months ended June
30, 2000 as compared  to  $261,584  for the same period in 1999,  an increase of
$25,963,  or 10%.  This  increase  was due to higher  production  costs and G&A,
offset by a decline in depletion.

Production  costs were  $247,177  for the three  months  ended June 30, 2000 and
$210,785 for the same period in 1999  resulting in a $36,392  increase,  or 17%.
This increase was the result of additional  well  maintenance  costs incurred to
stimulate  production  and  higher  production  taxes due to higher  oil and gas
prices.

During this period, G&A increased, in aggregate,  47% from $12,187 for the three
months ended June 30, 1999 to $17,899 for the same period in 2000  primarily due
to a higher  allocation of the managing  general  partner's G&A being  allocated
(limited to 3% of oil and gas  revenues)  as a result of  increased  oil and gas
revenues.

Depletion  was $22,471  for the three  months  ended June 30,  2000  compared to
$38,612  for the same  period in 1999,  a  decrease  of  $16,141,  or 42%.  This
decrease was primarily attributable to an increase in proved reserves during the
period ended June 30, 2000 as a result of higher commodity  prices, a decline in
oil  production  of 1,253  barrels  for the three  months  ended  June 30,  2000
compared  to the same period in 1999 and a reduction  in the  Partnership's  net
depletable  basis  from  charges  taken in  accordance  with SFAS 121 during the
fourth quarter of 1999.
