Talisman Energy (UK) Ltd. 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 is on Talisman 100% owned acreage, was tested with an exploration well drilled with theOcean Princess semisubmersible rig.
Talisman discovered a 302-ft 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 b/d on a 48/64-in. 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 tieback to the Tartan platform, with first production expected in the second half of 2004.
