Norwegian oil exploration and development company Aker BP has completed the drilling of 30/12-2 dry well south of Oseberg field in the North Sea.

The company said that the discovery had moderate reservoir quality. The 30/12-2 well is the first exploration well in production licence (PL) 986, awarded in APA 2018. Aker BP is the operator of PL 986 with 30% ownership interest. Petoro, Wellesley Petroleum and DNO Norge are the other licensees.

In August 2019, the company secured permit from the Norwegian Petroleum Directorate (NPD) pertaining to Section 15 of the Resource Management Regulations to drill wildcat well 30/12-2 using the Deepsea Stavanger drilling facility.

The well was drilled 3,173m deep vertically below the sea surface about 70km from the south of the Oseberg field centre and 160km west of Bergen towards northern region of the North Sea. The drilling was carried out to verify the presence of petroleum in Middle Jurassic reservoir rocks, the Tarbert and Ness formation.

Aker BP claimed the well encountered Tarbert formation with about 95m thickness. Moderate quality aquiferous reservoir rocks formed 20m of the formation.

The Ness formation was encountered with a thickness of about 65m, with moderate quality of 35m of aquiferous reservoir rock. Water depth at the site was 105m and the well, which is dry, has been plugged and abandoned.

The Deepsea Stavanger drilling facility is now drilling well 25/4-14 S in PL 036 C on the Alvheim field in the North Sea. Aker BP is the operator of this licence.
