The proved recoverable resources are provisionally estimated between 37 and 63 million barrels of oil. The volume of associated and free gas is estimated between one to three billion standard cubic metres of gas.

Geir Richardsen, head of exploration for acreage close to the infrastructure in the Norwegian Sea at Statoil, said: “I am pleased that we have made yet another discovery in the area north of the Norne field.”

Last year, Statoil discovered oil on the Dompap prospect, which also lies north of the Norne field.

Mr Richardsen said: “These discoveries demonstrate that also the deeper, western parts of the Norne area remain prospectable. This may well have a bearing on our field longevity work.”

Together with its partners, the company will consider developing the discovery through a tie-in to Norne, where the storage and production ship Norne receives production from seabed templates.

The partners on the PL128 license are: Statoil (operator, 63.95%), Petoro (24.55%) and ENI Norge (11.5%).
