Talisman Begins Production at North Tartan in the North Sea

Talisman Energy has commenced production at its North Tartan field at a rate of approximately 6,000 bbls/d. Production began two months ahead of schedule and within budget.

The North Tartan field is located in Block 15/16a adjacent to the Talisman operated Tartan platform, 118 miles northeast of Aberdeen in the Central North Sea. It lies entirely within Talisman 100% owned acreage and was successfully drilled and tested in August 2003 with an exploration well 15/16b-23. The well encountered a 302-foot oil column in high quality Jurassic aged Piper sandstones.

The North Tartan discovery was initially identified as a result of the new high-spec 3D seismic survey that Talisman acquired in 2001. Interpretation of this data set is ongoing and a number of similar opportunities in the Tartan area have been identified. The Tartan North field has been developed initially as a single well sub sea producer tied back to the Talisman 100% owned Tartan platform.

"This type of low cost, quick field development tied back to adjacent infrastructure is something Talisman does very well and, in our view, reflects a large part of the future of the North Sea," said Dr. Jim Buckee, President and Chief Executive Officer. "North Tartan generates high value per boe and boosts Talisman's current North Sea oil production by about four percent. It is a testament to the Talisman team and our key contractors that we have begun production only one year since the discovery well was drilled and tested."
