STATOIL has wrapped up its 2013-2014 exploration program in the Johan Castberg field with an oil and gas discovery in the Drivis prospect in the Barents Sea.

Well 7220/7-3 S, drilled by the rig West Hercules, has proven a 68 metre gross gas column in the Stø formation and an 86 metre gross oil column in the Stø and Nordmela formations, Statoil said in an announcement.

Statoil estimates the total volumes in Drivis to be between 44 million and 63 million barrels of recoverable oil equivalent, out of which between 42 million and 54 million were barrels of oil.

Comprising five wells, the campaign started in May 2013 with the aim of clarifying additional oil potential in the area, with Statoil senior vice president for exploration in the Norwegian Continental Shelf Irene Rummelhoff saying the campaign had delivered important subsurface information.

“We are certainly glad to have an oil discovery in Drivis. However, the exploration program as a whole has not delivered on volume expectations. Out of the five wells drilled only two have resulted in oil discoveries,” she said.

Statoil said it would now work closely with its partners in production licence PL532, Eni and Petoro, to analyse findings of the program and determine what it meant for the project.
