Wintershall has made North Sea oil discovery, the Norwegian Petroleum Directorate (NPD) today confirmed.
The operator is currently completing the drilling of four wildcat wells in the North Sea. The wells were drilled about five kilometres southeast of the Vega field in the North Sea and 100 kilometres southwest of Florø.
One of the wells well encountered a total oil column of 33 metres in intra Heather formation sandstone, of which 19 metres were of good reservoir quality. Due to technical issues, it was not possible to reach the Brent group and Cook formation.
A further well was drilled to further delineate the oil discovery in intra Heather formation sandstone.
The NPD said: “The well encountered a total oil column of 46 metres in intra Heather formation sandstone, of which 29 metres were of moderate reservoir quality. A total oil column of 19 metres was encountered in the Tarbert formation in the Brent group, of which 10 metres were of moderate reservoir quality.
“The Cook formation was encountered with a total thickness of about 170 metres with predominantly poor reservoir quality and only traces of petroleum.
“Preliminary estimates place the size of the discovery between 1.5 and 4.5 million standard cubic metres (Sm3) of recoverable oil equivalents.”
Wintershall will now analyse the discovery as well as nearby finds with the view toward potential development.
