Equinor Energy AS drilled a dry hole in wildcat well 31/2-23 S in North Sea production license (PL) 923, according to a release by the Norwegian Petroleum Directorate June 1. The well was drilled about 3 km west of Troll field and about 120 km northwest of Bergen.
The well, the fifth in the license, was drilled in 343 m of water by the Deepsea Stavanger drilling unit to a vertical depth of 2,333 m subsea. It was terminated in the Drake formation in the Lower Jurassic.
