LONDON, May 21 -- Talisman Energy Norge AS plans to drill an appraisal well to determine the size of its oil discovery in the Norwegian North Sea.
On test, wildcat well 15/12-21 flowed an average of 197 cu m/day of gas through a 20/64-in. choke. The well found a 133-m column in Middle Jurassic and Upper Triassic reservoir rocks and is 16 km north of Varg field and 15 km south of Sleipner Ost field.
Extensive data collection and sampling have also been carried out. "The size of the discovery has not yet been clarified because the oil-water contact was not proven," said Talisman. If profitable resources are proven, the discovery could be tied in to the Varg field.
Talisman drilled the well to a TVD of 3268 m below the sea surface using the Mærsk Guardian drilling rig and it ended in the Skagerrak formation in the Upper Triassic. The well was drilled in 86 m of water.
The discovery is on production license 038, which was awarded in the third licensing round in 1975.
Maersk Guardian will now drill appraisal well 15/12-21 A on the production license.
