The Norwegian Petroleum Directorate reported what it is calling a minor gas discovery made by Centrica Resources Norge AS.
Wildcat 6707/10-3 S was drilled about 20 km northeast of Aasta Hansteen field in the Norwegian North Sea. It was the first exploration well in production license 528 B, which was awarded in the 21st licensing round.
The well encountered a total gas column of about 12 m in the Kvitnos formation in the Upper Cretaceous with good reservoir properties, NPD said. The entire reservoir zone, including the water zone, has a gross thickness of 200 m, it said.
Based on extensive data acquisition and sampling, preliminary calculations of recoverable gas are 2-8 billion standard cu m. The well was not formation tested.
A secondary exploration target in the Upper Cretaceous Lysing formation was tight and aquiferous.
The well was drilled to a vertical depth of 4,264 m below the sea surface by the West Navigator drillship in 1,421 m of water. It was terminated in the Lange formation in the Lower Cretaceous.
