- E.ON Ruhrgas Drills Duster in North Sea

Norwegian Petroleum Directorate
E.ON Ruhrgas Norge AS, operator of production license 416, has completed the drilling of wildcat well 31/8-1. The well was drilled about 16 kilometers southwest of the Troll field.
The primary exploration target for the well was to prove petroleum in Upper Jurassic reservoir rocks (the Sognefjord formation). The secondary exploration target was to prove petroleum in Middle to Lower Jurassic reservoir rocks (the Fensfjord, Krossfjord and Johansen formations and the Brent group).
Reservoir rocks with expected reservoir quality were encountered in the Sognefjord formation, but the well was dry. No petroleum was proven in the secondary exploration targets either. Data acquisition and sampling have been carried out.
This is the first exploration well in production license 416. The license was awarded in APA 2006.
The well was drilled to a vertical depth of 2598 meters below the sea surface, and was terminated in the Brent group in the Middle Jurassic. Water depth at the site is 304 meters. The well will now be permanently plugged and abandoned.
Well 31/8-1 was drilled by the Borgland Dolphin drilling facility, which will now proceed to production license 471 in the Norwegian Sea to drill wildcat well 6407/5-2 S, where OMV Norge AS is the operator.
