OSLO -- Centrica Resources has completed its latest wildcat in the Norwegian sector as a dry well, according to the Norwegian Petroleum Directorate.
The chief target of well 6407/12-3, drilled by the semisub West Alpha in the Norwegian Sea, was to prove petroleum in Upper Jurassic reservoir rocks (Rogn formation). The secondary target was to prove petroleum in Mid-Jurassic reservoir rocks (Garn and Ile formations).
No reservoir sandstone was encountered in the Rogn formation. And although the Garn and Ile formations exhibited the anticipated reservoir quality, in each case the reservoir was thinner than expected.
The well was the first in production license 470, awarded under Norway’s APA 2007 round. The location was 13 km (8 mi) southeast of Norske Shell’s Draugen field. Water depth at the site was 228 m (748 ft).
TheWest Alpha will head next to Statoil’s Alve field in the Norwegian Sea to drill the observation and production wells 6507/3-L-4 H and 6507/3-L-4 AH.
