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 67% to $1,698,194 for the nine
months ended September 30, 2000 as compared to $1,014,766 for the same period in
1999.  The increase in revenues  resulted  from higher  average prices received,

                                        7

offset by a decrease in  production.  For the nine months  ended  September  30,
2000,  39,130 barrels of oil, 25,473 barrels of natural gas liquids ("NGLs") and
104,455 mcf of gas were sold, or 82,012 barrel of oil equivalents ("BOEs").  For
the nine months ended September 30, 1999,  37,683 barrels of oil, 29,702 barrels
of NGLs and 127,652 mcf of gas were sold, or 88,660 BOEs.

The average  price  received per barrel of oil  increased  $13.17,  or 85%, from
$15.44  for the nine  months  ended  September  30,  1999 to $28.61 for the same
period in 2000. The average price  received per barrel of NGLs increased  $5.36,
or 65%, from $8.31 during the nine months ended September 30, 1999 to $13.67 for
the same period in 2000. The average price received per mcf of gas increased 51%
from $1.46 during the nine months ended September 30, 1999 to $2.21 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.

Costs and Expenses:

Total  costs and  expenses  increased  to  $829,499  for the nine  months  ended
September  30,  2000 as compared  to  $787,176  for the same period in 1999,  an
increase of $42,323,  or 5%. 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 $691,478 for the nine months ended September 30, 2000 and
$606,234 for the same period in 1999 resulting in an $85,244  increase,  or 14%.
This increase was primarily due to higher production taxes of $55,539 associated
with higher oil and gas prices and additional well maintenance  costs of $21,346
incurred to stimulate well 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,  49% from $37,013 for the nine months ended  September
30,  1999 to  $55,175  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 $82,846 for the nine months ended  September 30, 2000 compared to
$143,929  for the same period in 1999,  representing  a decrease of $61,083,  or
42%. This  decrease was  attributable  to an increase in proved  reserves due to
higher  commodity  prices as compared  to the same period in 1999,  offset by an
increase in oil production of 1,447 barrels for the nine months ended  September
30, 2000 compared to the same period in 1999.

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

Revenues:

The Partnership's  oil and gas revenues  increased 40% to $615,825 for the three
months ended  September  30, 2000 as compared to $441,421 for the same period in
1999. The increase in revenues resulted from  higher  average  prices  received,

                                        8

offset by a decrease in  production.  For the three months ended  September  30,
2000,  12,371  barrels of oil,  9,166 barrels of NGLs and 36,292 mcf of gas were
sold,  or 27,586 BOEs.  For the three months ended  September  30, 1999,  12,626
barrels of oil,  11,309  barrels  of NGLs and  46,764  mcf of gas were sold,  or
31,729 BOEs.

The average  price  received per barrel of oil  increased  $11.33,  or 58%, from
$19.41 for the three months ended  September 30, 1999 compared to $30.74 for the
same period in 2000.  The average  price  received per barrel of NGLs  increased
$4.07,  or 39%, from $10.32 during the three months ended  September 30, 1999 to
$14.39 for the same period in 2000.  The average  price  received per mcf of gas
increased  68% from $1.70 during the three months  ended  September  30, 1999 to
$2.86 for the same period in 2000.

Costs and Expenses:

Total costs and  expenses  increased  to  $271,768  for the three  months  ended
September  30,  2000 as compared  to  $255,255  for the same period in 1999,  an
increase of $16,513,  or 6%. This  increase was due to  increases in  production
costs and G&A, offset by a decline in depletion.

Production costs were $226,699 for the three months ended September 30, 2000 and
$204,910 for the same period in 1999,  resulting in a $21,789 increase,  or 11%.
The increase was primarily due to higher production taxes of $20,195  associated
with higher oil and gas prices,  offset by a decrease in well maintenance  costs
of $7,774.

During this period, G&A increased, in aggregate,  21% from $17,369 for the three
months ended September 30, 1999 to $21,036 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 $24,033 for the three months ended  September 30, 2000 compared to
$32,976 for the same period in 1999, a decrease of $8,943, or 27%. This decrease
was  attributable  to an  increase  in  proved  reserves  as a result  of higher
commodity prices and a decline in oil production of 255 barrels when compared to
the respective information for the same period in 1999.

Liquidity and Capital Resources

Net Cash Provided by Operating Activities

Net cash provided by operating  activities  increased  $642,704  during the nine
months  ended  September  30,  2000  from the same  period  ended in 1999.  This
increase  was due to an  increase  in oil and gas sales  receipts  of  $741,659,
offset by increases in production costs paid of $76,873 and G&A expenses paid of
$22,082.

Net Cash Used in Investing Activities

The Partnership's  principal  investing  activities during the nine months ended
September 30, 2000 and 1999 included  equipment  upgrades on various oil and gas
