18/05/2009 Press Release 26/2009 Talisman Energy Norge AS, operator of production licence 038, has concluded the drilling of wildcat well 15/12-21. The well, which proved oil, is located 16 km north of the Varg field and 15 km south of the Sleipner Øst field in the North Sea.

The purpose of the well was to prove petroleum in Middle Jurassic and Upper Triassic reservoir rocks, where a 133-metre oil column was encountered. The size of the discovery has not yet been clarified because the oil/water contact was not proven. An appraisal well will be drilled to determine the size of the oil discovery. If profitable resources are proven, the discovery could be tied in to the Varg field.

Extensive data collection and sampling have been carried out, as well as a successful formation test. The average production rate was 197 cubic metres of oil per day through a 20/64" nozzle opening.

This is the 22nd exploration well in production licence 038, which was awarded in the 3rd licensing round in 1975.

The well was drilled to a vertical depth of 3268 metres below the sea surface, and concluded in the Skagerrak formation in the Upper Triassic.

The well was drilled by the Mærsk Guardian facility in 86 metres of water. The facility will now drill appraisal well 15/12-21 A on the production licence.
