Statoil Completes Latest Johan Sverdrup Appraisal Well

Norway's Statoil confirmed Thursday that it has completed its latest appraisal well on the Johan Sverdrup discovery in the Norwegian North Sea.
Late on Wednesday, the Norwegian Petroleum Directorate reported that well 16/2-15 encountered a 99-foot gross oil column in Upper Middle Jurassic reservoir rocks, of which about 65 feet were of "very good reservoir quality". The NPD also reported that the oil/water contact was encountered at the same depth as neighboring wells.
Well 16/2-15 – the 10th exploration well on production license 265, which contains Johan Sverdrup – was drilled approximately three miles southwest of the 16/2-6 discovery well and 1.5 miles south of appraisal well 16/2-11.
The NPD said that extensive data acquisition and sampling have been carried out, with two formation tests conducted in the uppermost part of the Jurassic reservoir, where the reservoir quality "was not good". However, the NPD added that the pressure data indicates that this reservoir zone is in communication with the best part of the reservoir.
On Thursday Gro Haatvedt, Statoil's senior vice president for exploration in Norway commented in a company statement:
"We are satisfied with the results of our appraisal program… We have proven new volumes to Johan Sverdrup in the Geitungen segment, and drilled two important appraisal wells in the central and southern parts of the licence."
Haatvedt also confirmed that Statoil would continue to appraise Johan Sverdrup in 2013 with up to three new wells.
Well 16/2-15 was drilled to a vertical depth of 6,510 feet below the sea surface. It was drille3d with the Ocean Vanguard (mid-water semisub) rig, which will now drill wildcat well 25/11-26 in production license 169.
