</Table>

Net income totaled $15.8 million or $0.52 per diluted share, a 56% increase over
last year's quarter. Oil and natural gas revenues achieved $55.7 million during
the quarter and cash flow from operations rose to $43.7 million, increases of
28% and 130%, respectively, from the same period last year. Third quarter
results reflected a 16% increase in average realized prices received on a boe
basis.

During the third quarter of 2003, Encore's average daily production reported
increased to 22,663 boe per day, an increase of 11% over the same period in
2002. The company's growth in production, which is currently 81% oil, was
achieved with the Company's continued development success at both the Cedar
Creek Anticline ("CCA") and the Permian Basin along with successful acquisitions
in the Elm Grove Field (August 2003) and the Paradox Basin (September 2002).
Also contributing to the increase in production was the decline in the Company's
net profits interest payment during the third quarter of 2003 due to the
development capital incurred in the CCA's Pennel unit.

Realized prices adjusted for hedging, averaged $26.52 per barrel and $4.60 per
Mcf during the third quarter 2003, increases of 10% and 46%, respectively, from
the prior year third quarter. On a combined basis, prices increased 16% during
the third quarter of 2003 to $26.73 per boe from $23.14 per boe for the same
period last year.

Lease operating expenses ("LOE") were $4.70 per boe for the third quarter of
2003, lower than anticipated due to decreased maintenance costs and higher
production. General and administrative ("G&A") expenses during the third quarter
of 2003 were $0.96 per boe, an increase of $0.12 from the same period last year
primarily due to an increase in staffing requirements and increased outside
consulting services used in the evaluation of potential acquisitions.
Depreciation, depletion and amortization ("DD&A") was $4.06 per boe during the
three months ended September 30, 2003, compared to $4.80 per boe for the same
period last year. The decrease is attributable to the Company's adoption of
Statement of Financial Accounting Standards No. 143 "Accounting for Asset
Retirement Obligations" in the first quarter of 2003 and the increase in the
Company's reserves at year-end December 31, 2002. Interest expense during the
third quarter of 2003 decreased 3% to $4.0 million from $4.1 million in the same
period last year due to average interest rates partially offset by an increase
in debt balances.



During the third quarter 2003, the Company invested $52.5 million for the Elm
Grove acquisition in Northern Louisiana. Currently two non-operated rigs are
running in this area and are expected to continue through the end of the year.
In addition to the acquisition, the Company invested $25.5 million in its
development and exploitation program, which resulted in 18 (11.9 net) vertical
wells, six (5.4 net) horizontal wells, ten (9.2 net) re-entry wells and five
(5.0 net) service/injection wells.

At September 30, 2003, the Company's long-term debt was $181.0 million, of which
$31.0 million represents debt under the Company's credit facility. The increase
of $31.0 million from June 30, 2003 is attributable to the acquisition of the
Elm Grove properties. As previously mentioned the acquisition price of the Elm
Grove properties was $52.5 million, resulting in approximately 41% of the
purchase price funded by the Company's cash flow from operations. Since quarter
end, debt has been reduced further by $3.0 million. In October 2003, the credit
facility's borrowing base was increased to $270.0 million from $220.0 million
effective December 1, 2003.

Jonny Brumley, President, commented "we had an exceptional quarter and are very
pleased. We continue to generate high returns through our development program,
and we are excited about the high-pressure air injection program that will start
up in Little Beaver during the fourth quarter of this year. The Company's stable
production and strong balance sheet will enable us to implement our strategy of
growing through development drilling, acquisitions, and tertiary projects. The
balance sheet continues to be strong as our cash flow has allowed us to reduce
our debt position since the Elm Grove acquisition".

This press release includes forward-looking statements. Forward-looking

pursuing acquisitions; difficulties integrating acquisitions; complications
resulting from increasing the scope and geographic diversity of our operations ;
inaccuracies in the assessment of reserves and daily and annual production;

expenses, production taxes and other items of income and expense; the amount,
nature and timing of capital expenditures; drilling of wells; timing and amount
of future production of oil and natural gas; operating hazards; operating costs
