Wintershall Norge has completed drilling of two wildcat wells, 35/8-6 S and 35/8-6 A, that are located 5km northwest of Vega field in the North Sea.

The wells were drilled in a bid to discover petroleum in the region’s upper jurassic reservoir rocks.

While drilling 35/8-6 S revealed a poorly developed reservoir, drilling 35/8-6 A unveiled a 3m oil column in the rock’s heather formation.

"Extensive data collection and sampling have been carried out after the drilling."

Preliminary estimates on the size of the discovery range between 0.2 and 1 million standard cubic metres of recoverable oil.

Extensive data collection and sampling have been carried out following the drilling.

The two wells were drilled to a measured depth of 4,043m and 3,800ml and to a vertical depth of 3,713m and 3,529m, respectively.

They have now been permanently plugged and abandoned.

The two wells were drilled by Borgland Dolphin.

The company will now drill wildcat well 35/11-19 S, which also operated by Wintershall Norge under production licence 248.
