OSLO, Norway – The semisubmersible Deepsea Bergen has finished drilling appraisal well 15/3-11 on the 15/3-4 (Sigrun) oil and gas discovery for Equinor in license PL 025 in the Norwegian North Sea.

The location was drilled in 109 m (357 ft) water depth, 10 km (6.2 mi) southeast of the Gudrun field and roughly 225 km (140 mi) west of Stavanger.

Equinor was seeking to delineate the 1982 15/3-4 discovery in three reservoir zones in the Mid-Jurassic (Hugin formation).

The latest well encountered a 35-m (115-ft) gross oil column in this formation, with a 15-m (49-ft) thick sandstone layer of poor to moderate reservoir quality.

According to the Norwegian Petroleum Directorate, results suggest 1.1-2 MMcmoe recoverable.

The Deepsea Bergen will next drill wildcat well 35/10-4 S for Equinor in PL 360 in the northern Norwegian North Sea.
