Neptune Energy Norge AS, operator of production licence 938, has completed the drilling of wildcat well 6407/8-8 S.

The well was drilled about 14 kilometres northwest of the Draugen field in the Norwegian Sea, and 144 kilometres north of Kristiansund.

The well's primary exploration target was to prove petroleum in Middle Jurassic reservoir rocks belonging to the Garn formation (the Fangst Group). The secondary exploration target was to prove petroleum in Middle to Lower Jurassic reservoir rocks belonging to the Ile and Tilje formations (Fangst and Båt groups).

In the primary exploration target, well 6407/8-8 S encountered an 8-metre thick gas column and a 30-metre thick oil column in the Garn formation, which is a total of 131 metres thick. Reservoir quality in the hydrocarbon column is good to very good. The oil/water contact was encountered at 2998 metres.

In the secondary exploration target, the well encountered aquiferous sandstone reservoirs belonging to the Ile and Tilje formations. Reservoir thickness is 79 metres in the Ile Formation and 145.5 metres in the Tilje Formation. Reservoir quality varies from poor to moderate in both formations.

The preliminary calculation of the size of the discovery is between 1.0 and 3.5 million Sm3 of recoverable oil equivalent. The licensees will assess the discovery with a view toward a possible development using nearby infrastructure.

Extensive data acquisition and sampling have been carried out in the well, including small-scale formation testing in the Garn Formation.
This is the first exploration well in production licence 938, which was awarded in APA 2017.

Well 6407/8-8 S was drilled to a vertical depth of 3496 metres below sea level and was terminated in the Tilje Formation from the Early Jurassic.

The water depth is 271 metres, and the well has now been permanently plugged and abandoned.

Well 6407/8-8 S was drilled by the Deepsea Yantai drilling facility, which is now headed to CCB at Ågotnes.
