Statoil, together with PL272 partners, has discovered gas in the Askja West prospect and oil in the Askja East prospect in the North Sea.

Drilled by the rig Ocean Vanguard, exploration wells 30/11-9 S and 30/11-9 A are located between the Oseberg and Frigg fields, about 13km south-east of the Krafla / Krafla West discoveries operated by Statoil.

The 30/11-9 S Main wellbore, which tested the Askja West prospect, proved a net gas column of 90m in Late and Middle Jurassic rocks.

Testing the Askja East prospect, Side-track 30/11-9 A proved a net oil column of 40m in the same geological formations.

According to the company, the reservoir properties were as expected in both wells and total volumes in Askja West and Askja East are estimated to be in the range of 19 – 44 million barrels of recoverable oil equivalent.

Statoil vice president exploration North Sea May-Liss Hauknes said the highly prolific petroleum basin North Sea has delivered new discoveries consistently for more than four decades.

"We are pleased to start 2014 with a gas and oil find in the Askja West and East prospects, in the very heart of the North Sea," Hauknes added.

The discovery is claimed to demonstrate that even the most mature parts of the NCS still have a value creation potential.

Statoil field development vice president Knut Skjoldli said: "Askja will be considered developed together with the Krafla and Krafla West discoveries made by Statoil in 2011."

Statoil operates the wells with an interest of 50% and partners include Svenska Petroleum Exploration (25%) and Det norske oljeselskap (25%).
