Aker BP drills dry well in Yggdrasil area

Aker BP drilled a dry well in the Yggdrasil area in the North Sea.

Well 30/11-16 S (Natrudstilen) was drilled in 112 m of water by the Deepsea Stavanger rig in production license (PL) 873, about 1 km east of Fulla and 155 km west of Bergen, the Norwegian Offshore Directorate reported. The well reached a vertical depth of 4,327 m subsea. It was terminated in the Tarbert formation in the Middle Jurassic.

The objective was to prove petroleum in the Natrudstilen prospect. The well encountered about 350 m of the Tarbert formation, 197 m of which were sandstone with moderate to poor reservoir quality. The well is classified as dry with hydrocarbon shows, however hydrocarbon shows were observed in the Hardråde formation and Tryggvason formation in the Upper Cretaceous.

Data was collected, including pressure points in the upper part of the Tarbert formation. The well has now been permanently plugged.
