DNO ASA announced a “play opener” oil discovery offshore Norway, its second significant discovery in two years.

The Othello discovery is the first time moveable oil has been encountered in the Borr unit of the Vale Formation, DNO said. Othello was drilled in an eastern section of the basin previously known as “the dry belt.”

The company drilled two wells in the formation, and the shallower prospect hit. Preliminary estimates show gross recoverable resources of 27 MMboe to 57 MMboe, with a mean estimate of 41 MMboe.

DNO holds a 50% operated interest in the license. Aker BP ASA and Petoro AS hold 20% each, and Source Energy AS the remaining 10%. The partners are considering tying back the discovery to existing infrastructure. The ConocoPhillips Ekofisk hub is 25 miles west of Othello and Aker’s Valhall hub is 35 southwest.

Last year, DNO announced the Norma gas condensate discovery in the Norwegian North Sea.
