German oil and gas firm Wintershall has made an oil discovery at its Skarfjell prospect in the Norwegian North Sea.

The company said that the wildcat well 35/9-7, located in production licence 418, found Upper Jurassic reservoir sands of good quality, containing light oil with a significant oil column.

The well was drilled using the Songa Delta Rig, located just north of the Titan discovery and 17km south-west of the Gjøa Field.

Wintershall board member in charge of exploration and production Martin Bachmann said the Skarfjell discovery is another important milestone for the company and adds further growth potential to its portfolio on the Norwegian Continental Shelf.

"We are confident of the quality of our projects both in exploration and development and continue to strongly pursue our ambitious targets for the northern North Sea," said Bachmann.

The well was drilled to a vertical depth of 2,976m below sea level, and finished in the Middle Jurassic Brent Group / Rannoch Formation.

The company estimates a preliminary resource range between 60 and 160 million barrels of recoverable oil.

Due to limitation in the rig slot length, the well was not tested but reservoir and fluid sampling have given valuable data on the new discovery.

The Skarfjell probe will now be permanently plugged and abandoned, after which time the rig will move on to drill an appraisal well 33/6-3S for Suncor Energy.

Wintershall Norge holds a 35% interest in license 418, while Bayerngas Norge and Agora Oil and Gas each have a 20% stake, Edison International Norway has a 15% interest and RWE Dea Norge holds 10%.
