Det norske oljeselskap ASA has, as partner in PL 265 (20 percent), explored a potential on the basement high to the west of the main fault and to the west of the Johan Sverdrup field.
Exploration well 16/2-18 S, the Cliffhanger North prospect, did not find sandstone reservoir from the Jurassic in the primary objective.
Core sampling has confirmed oil shows in basement rocks in the secondary target.
Data sampling and interpretation is still ongoing. Final results are thus not yet available.
