Offshore staff

OSLO, Norway – The semisubmersible Borgland Dolphin is completing a four-well campaign for Wintershall in production license 248 F in the Norwegian North Sea.

All were drilled in 373 m (1,224 ft) of water, around 5 km (3 mi) southeast of the Vega field and 100 km (62 mi) southwest of Florø.

Well 35/11-20 S encountered an 8-m (26-ft) oil column in the secondary exploration target at the top of an intra-Heather formation sandstone, with poor reservoir quality and a total thickness of about 70 m (229 ft).

Well 35/11-20, designed to delineate the discovery, intersected a 33-m (108-ft) oil column in intra Heather formation sandstone, of which 19 m (62 ft) were of good reservoir quality.

However, technical issues prevented drilling into the Brent group and Cook formation.

Well 35/11-20 B encountered a total oil column of 46 m (151 ft) in intra Heather formation sandstone, of which 29 m (95 ft) were of moderate reservoir quality.

The Norwegian Petroleum Directorate assesses reserves in the range of 1.5-4.5 MMcmoe recoverable. Wintershall and its partners will evaluate potential for a development with other nearby discoveries.
