Oil and gas discovery northwest of the Draugen field in the Norwegian Sea
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.
There are vast proven gas resources on the Norwegian shelf which are currently without development plans. Much of this gas is located in tight reservoirs – which makes it difficult to produce.
The Norwegian Petroleum Directorate (NPD) has conducted a mapping of gas resources that, for various reasons, have yet to be developed. Several of these discoveries could be produced in a manner that is profitable from a socio-economic perspective.
The Norwegian Petroleum Directorate (NPD) has granted Harbour Energy Norge AS drilling permit for well 15/9-25 in production licence 1138, cf. Section 13 of the Resource Management Regulations.
The Norwegian Petroleum Directorate (NPD) is changing its name to the Norwegian Offshore Directorate as of 1 January 2024. The new name reflects the additional responsibilities assigned to the directorate in recent years.
