Statoil makes oil discovery north of the Grane field

STAVANGER -- Statoil is about to complete drilling of wildcat well 25/11-27, which proved oil, in the Grane Unit, where the company is operator.

The well encountered an oil column of about 20 m in the Heimdal formation. Preliminary estimates put the discovery in the range of 18-33 million barrels of recoverable oil. The licensees will consider various development alternatives, based on oil quality and pressure communication with surrounding fields.

The objective of the well was primarily to prove petroleum in Paleocene reservoir rocks (the Heimdal formation), but also to find out if there could be communication with the Grane field, in the event of a discovery.

The well was drilled within license 169 B2, roughly seven km north of the Grane field, in the central part of the North Sea, and about 150 km west of Stavanger. Statoil is operator, with an interest of 36.66%. The partners are Petoro (28.94%), ExxonMobil Exploration & Production Norway (28.22%) and ConocoPhillips Skandinavia (6.17%).

Extensive data acquisition and sampling have been carried out.

This is the fifth exploration well drilled by the licensees in Grane Unit. Well 25/11-27 was drilled to a vertical depth of 1,865 m below the sea surface, and was terminated in the Shetland Group, most likely in the Lower Paleocene, but upper Cretaceous cannot be excluded. The well will now be permanently plugged and abandoned. The water depth is 126 m.

The well was drilled by the Songa Trym vessel, which will now proceed to production license 128 in the Norwegian Sea, to drill appraisal well 6608/11-8, where Statoil is operator.
