Talisman Energy Announces Successful Test in Quebec

CALGARY, ALBERTA, Sep 02 (MARKET WIRE) --
Talisman Energy Inc. (TSX: TLM) (NYSE: TLM) announced a successful test
from the Utica shale in its Gentilly well in Quebec. The Gentilly well is
located on the south side of the St. Lawrence River, approximately 100
kilometers south of Quebec City. Talisman holds a 75% interest in the
well and is operator.

The well, which is a re-entry to a previously drilled Trenton-Black River
well, flowed at 800 mcf/d from one completed interval on a sustained
basis during the 18-day test period. At the time of shut in, the well was
still cleaning up and pressures and flow rates were constant.

"We are encouraged by the initial results of this vertical well," said
John A. Manzoni, President and Chief Executive Officer. "We have
additional testing to do on the well, including zones within the Basal
Lorraine and Lorraine shale formation, but this is a very promising start
to our unconventional program in Quebec."

The Lorraine shale sits on top of the Utica and can be up to 6,500 feet
thick. The Utica shale ranges between 300 and 1,000 feet. Early
indications show that both the Lorraine and Utica rocks are thick, porous
and appear brittle and over pressured, all of which are conducive to
artificial fracture stimulation.

Talisman has an extensive land position with an option to earn 760,000
net acres through drilling in Quebec. The Company is in the early stage
of evaluating the rock properties and reservoirs. Talisman will test
three to four pilot areas over the next 18 months, with up to four
additional wells planned prior to year-end.
