OSLO, Norway – Equinor Energy has discovered commercial oil in an accumulation northwest of the Vigdis West field in the northern Norwegian North Sea.
The semisubmersible Transocean Norge drilled well 34/7-E-4 AH AS in production license 089 in 283 m (928 ft) of water, and 160 km (99.4 mi) west of Florø. It was a shallow side track from development well 34/7-E-4 H on the Vigdis field.
According to the Norwegian Petroleum Directorate (NPD), the side track penetrated a 20-m (65.6-ft) oil column in the mid-Jurassic Rannoch formation, most of which was sandstone of good reservoir quality. The oil/water contact was at a depth of 2,479 m (8,133 ft).
The NPD assesses recoverable reserves in the range 0.9-1.5 MMcm, which could be developed via a tie-in to the Vigdis facilities.
The Transocean Norge will next drill a development well on the Visund South field, again for Equinor.
