Published at 08:45AM - 31/08/16

Det norske oljeselskap announced an offshore oil discovery of between 24 and 74 million barrels of oil equivalent (boe) at the Langfjellet prospect, located in the North Sea.

The oil and gas company is the operator of production licence PL 442 and was drilling exploration well 25/2-18 S.

“A technical sidetrack was drilled to collect data and the well is currently being prepared for a sidetrack and well test,” the company informed in a statement.

According to Det norske’s statement, the well encountered a gross oil column of 109 metres (357 feet) in the Vestland Group.

The licensees are now expected to evaluate the finding in terms of a potential development along with other discoveries in the same area, after having identified further prospects in the area.

Drilling is nearly complete and will be finalized according to schedule, as it had initially been estimated that drilling activities would last between 31 and 80 days.

The Norwegian Petroleum Safety Authority (PSA) had granted Det norske consent for exploratory drilling in the production licence earlier this month and a drilling permit had been issued for the well in July.

The production licence is owned by Det norske (90%) with partner LOTOS Exploration and Production Norge AS (10%).

Maersk Interceptor Drills North Sea Well

Det norske had taken operatorship in PL 442 from Centrica in an agreement signed in April this year.

The company used the Maersk Interceptor jack-up rig to drill the Langfjellet prospect. The rig, built by Keppel FELS Shipyard in Singapore in 2014, is operated by Maersk Drilling Norge.

Det norske will use the Maersk Interceptor later this year to drill production wells at Ivar Aasen in the North Sea, also operated by the company.

The jack-up will drill a further three wells for the Ivar Aasen production/drilling/quarters (PDQ) facility in late November, estimated to last until July 2017.
