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

Results of Operations

Nine months ended  September 30, 2000 compared with nine months ended  September
  30, 1999

Revenues:

The Partnership's oil and gas revenues  increased 59% to $1,716,120 for the nine
months ended September 30, 2000 as compared to $1,077,179 for the same period in
1999.  The increase  in revenues  resulted from  higher average prices received,

offset by a decrease in  production.  For the nine months  ended  September  30,
2000,  38,681 barrels of oil, 23,453 barrels of natural gas liquids ("NGLs") and
103,116 mcf of gas were sold, or 79,320 barrel of oil equivalents ("BOEs").  For
the nine months ended September 30, 1999,  41,744 barrels of oil, 27,047 barrels
of NGLs and 122,076 mcf of gas were sold, or 89,137 BOEs.

The average  price  received per barrel of oil  increased  $13.42,  or 87%, from
$15.35  for the nine  months  ended  September  30,  1999 to $28.77 for the same
period in 2000. The average price  received per barrel of NGLs increased  $5.93,
or 67%, from $8.89 during the nine months ended September 30, 1999 to $14.82 for
the same period in 2000. The average price received per mcf of gas increased 54%
from $1.61 for the nine months  ended  September  30, 1999 to $2.48 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 nine months ended September 30, 2000.

Gain on disposition  of assets of $5,351 was  recognized  during the nine months
ended September 30, 2000 from equipment credits received on one well.

Costs and Expenses:

Total  costs and  expenses  increased  to  $836,923  for the nine  months  ended
September  30,  2000 as compared  to  $814,030  for the same period in 1999,  an
increase of $22,893,  or 3%. This  increase was due to  increases in  production
costs and general and  administrative  expenses ("G&A"),  offset by a decline in
depletion.

Production  costs were $701,985 for the nine months ended September 30, 2000 and
$621,887 for the same period in 1999 resulting in an $80,098  increase,  or 13%.
This increase was primarily due to higher production taxes of $53,590 associated
with higher oil and gas prices and additional well maintenance costs incurred to
stimulate well production of $21,923.

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,  43% from $39,515 for the nine months ended  September
30,  1999 to  $56,487  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 $78,451 for the nine months ended  September 30, 2000 compared to
$152,628  for the same period in 1999,  representing  a decrease of $74,177,  or
49%. This  decrease was  attributable  to an increase in proved  reserves due to
higher commodity prices as compared to the same period in 1999, a decline in oil
production  of 3,063  barrels  for the nine  months  ended  September  30,  2000
compared  to the same  period in 1999 and a  decline  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 September 30, 2000 compared with three months ended September
  30, 1999

Revenues:

The Partnership's  oil and gas revenues  increased 36% to $620,233 for the three
months ended  September  30, 2000 as compared to $456,178 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  September  30,
2000,  12,754  barrels of oil,  7,440 barrels of NGLs and 32,864 mcf of gas were
sold,  or 25,671 BOEs.  For the three months ended  September  30, 1999,  14,014
barrels of oil, 9,892 barrels of NGLs and 42,784 mcf of gas were sold, or 31,037
BOEs.

The average  price  received per barrel of oil  increased  $11.44,  or 59%, from
$19.34 for the three  months  ended  September  30,  1999 to $30.78 for the same
period in 2000. The average price  received per barrel of NGLs increased  $5.84,
or 55%, from $10.54  during the three months ended  September 30, 1999 to $16.38
for the same period in 2000. The average price received per mcf of gas increased
70% from $1.89 for the three  months ended  September  30, 1999 to $3.22 for the
same period in 2000.

Costs and Expenses:

Total costs and  expenses  increased  to  $269,677  for the three  months  ended
September  30,  2000 as compared  to  $255,504  for the same period in 1999,  an
increase of $14,173,  or 6%. This  increase was due to  increases in  production
costs and G&A, offset by a decline in depletion.

Production costs were $221,858 for the three months ended September 30, 2000 and
$204,913 for the same period in 1999 resulting in a $16,945 increase, or 8%. The
increase was primarily  due to higher  production  taxes of $ 19,499  associated
with higher oil and gas prices, offset by a decline in well maintenance costs of
$7,227.

During this period, G&A increased, in aggregate,  19% from $18,189 for the three
months ended September 30, 1999 to $21,699 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 $26,120 for the three months ended  September 30, 2000 compared to
$32,402 for the same period in 1999,  representing a decrease of $6,282, or 19%.
This decrease was  attributable to an increase in proved reserves as a result of
higher commodity prices as compared to the same period in 1999, a decline in oil
production  of 1,260  barrels  for the three  months  ended  September  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.
