Talisman Makes North Sea Discovery

Talisman Energy (UK) Limited, a wholly owned subsidiary of Talisman Energy Inc., has made a new oil discovery in Block 15/16a of the UK North Sea, adjacent to the Talisman operated Tartan platform.

The TNT-B exploration prospect, which lies entirely within Talisman 100% owned acreage, was successfully tested with an exploration well drilled with the Ocean Princess semi-submersible rig. The well discovered a 302-foot oil column in Jurassic aged Piper sandstones, with porosities of the oil-bearing sands averaging 14%.

The well was tested and flowed at rates to 8,100 bbls/d at a 48/64-inch choke with 1,535 psi tubing head pressure and was constrained by surface testing equipment. The well has been completed as a future subsea producer via a single well tie-back to the Tartan platform, with first production expected in the second half of next year.

"This excellent result from Talisman's latest exploration well reinforces the continuing potential of our North Sea portfolio and the success of our integrated core area strategy," said Dr. Jim Buckee, President and Chief Executive Officer.

Talisman holds a 100% interest in the 15/16a licence Block, which contains the Tartan field and the discovery well.
