ENCORE ACQUISITION COMPANY ANNOUNCES $55 MILLION ACQUISITION, SETS CONFERENCE
CALL TO DISCUSS TRANSACTION

FORT WORTH, Texas - November 9, 2001 - Encore Acquisition Company ("Encore")
(NYSE: EAC) announced today that it has agreed to acquire oil and gas properties
in the Permian Basin from a major integrated oil company. The purchase price is
$55 million, prior to closing adjustments. The two principal operated properties
are the East Cowden Grayburg and the Fuhrman Nix fields, and the non-operated
properties are the Yates and North Cowden fields. These West Texas fields are
located in Ector, Andrews, Crockett and Pecos Counties.

Jon Brumley, Chairman, President and CEO stated, "I like this acquisition. These
properties are exactly what we do best: acquire and enhance existing oil fields.
The properties will have significant in-field drilling opportunities. The
properties meet Encore's business strategy, in that production can be held flat
with less than 1/2 of cash flow and the remaining 1/2 can be used for growth."

The acquisition is accretive to cash flow and allows Encore to continue to
expand future cash flow with internally generated opportunities. Based on its
development plans and a $22.50 oil price, Encore believes that the 2002 cash
flow will exceed $8.5 million and produce around 1,950 barrels of oil equivalent
per day.

Encore estimates that existing proved reserves are in excess of 10 million
barrels. Over 40 development wells have been identified, and the drilling
program will be initiated in the second half of 2002. The revenue mix is 97%
oil, the reserve to production ratio is over 15 years and over 73% of the
acquisition is operated.

For the Permian Basin acquisition, Encore has hedged 1,000 barrels of oil per
day, 52% of the acquisition's expected oil production for 2002, using a collar
with a floor of $20.00 and a cap of $23.73. With these new positions, Encore has
hedged a total of 9,500 barrels of oil per day for 2002 by utilizing swaps,
floors and caps.

For Encore's option-based hedges, the weighted average floor price for 2002 is
$22.60 per barrel with 7,000 barrels of oil per day protected by floors. The
weighted average ceiling price is $26.30 per barrel, with only 2,500 barrels of
oil per day capped. In addition to these hedges, Encore has swapped 2,500
barrels of oil per day for 2002 at a fixed price of $19.47 per barrel. As a
result of this option-based hedging strategy, approximately 58% of Encore's 2002
estimated oil production is protected to the downside, while only 30% of 2002
estimated oil production is subject to a ceiling.

Encore expects to close the transaction, which is subject to due diligence, in
January of 2002 and expects to fund the transaction with bank financing under
its existing credit line. The effective date for this transaction is January 1,
2002.
