The Norwegian Petroleum Directorate reported results from an appraisal well drilled in the North Sea by Statoil ASA, operator of production license 035.
Statoil drilled the well to delineate the 30/11-8 S discovery in 2011, about 25 km southwest of the Oseberg Sor field facility in the northern North Sea (OGJ Online, May 10, 2011).
Appraisal well 30/11-10 A was drilled north of the discovery well. The well encountered a total oil column of about 260 m in the Tarbert formation. Preliminary size is calculated at 8-13 million standard cu m of recoverable oil equivalent.
The Transocean Leader semisubmersible rig drilled to a vertical depth of 3,673 m below the sea surface, terminating in the Ness formation in the Middle Jurassic. Water depth is 105 m.
The well will be permanently plugged and abandoned. NPD said it was the ninth well related to exploration drilled in PL 035, which was awarded in the 2nd licensing round in 1969.
