Norwegian oil exploration and development company Aker BP has found minor oil while drilling in the Gyda area in the southern Norwegian North Sea.

Maersk Interceptor ultraharsh-environment jack up rig drilled the 2/1-17 S well in production licence (PL) 019 C, 10km south of Gyda field and 280km southwest of Stavanger. It was drilled to a vertical depth of 4,322m and a measured depth of 4,334m subsea.

The well was drilled at a water depth of 66m. The primary exploration target, which was to prove petroleum in Upper Jurassic reservoir rocks, was not met in the well.

According to the Norwegian Petroleum Directorate (NPD), the well found oil in the Eldfisk formations as part of the second exploration target. Eldfisk formation was discovered with a layer of about 5m of oil-bearing good reservoir quality sandstones. Aker BP assessed this minor oil discovery as uncommercial.

In a press statement, NPD said: “The well was not formation-tested, but extensive volumes of data have been collected.”

The exploration well is the second to be drilled in PL 019 C. Early analysis places the size of the discovery at 0.5-1.5 million standard cubic metres of recoverable oil.

The well, which was terminated in the Tyne Group in the Upper Jurassic, will now be permanently plugged and abandoned, noted NPD.

The Maersk Interceptor drilling facility will now drill development wells in PL 001 B on the Ivar Aasen field in the North Sea.
