Equinor Energy is concluding the drilling of exploration well 30/11-15 in the North Sea. The well is dry.
The well was drilled by the “Deepsea Stavanger” drilling rig, about 25 km southwest of the Oseberg field in the North Sea and 150 km west of Bergen.
Equinor has drilled the well on behalf of Aker BP, which is the operator of the production licence. The two companies each hold a 50% ownership interest in the licence. This is the 14th exploration well in production licence 035, which was awarded in 1969. Munin was discovered in 2011, and the plan for development and operation (PDO) was approved in June 2023. Following the Munin discovery, an additional seven exploration wells have been drilled in this production licence, three of which have resulted in discoveries.
The primary exploration target for the well was to prove petroleum in Lower Jurassic reservoir rocks in the Statfjord Group. The secondary target was sampling and logging previously proven petroleum deposits from the Middle Jurassic Brent Group.
Well 30/11-15 encountered the Statfjord Group at about 382 meter gross thickness, with reservoir rocks totalling 58 metres with poor reservoir quality. Data acquisition was carried out.
The well encountered the Brent Group with reservoir properties and hydrocarbon columns as expected. The discovery in well 30/11-8 S was proven in 2011. Data acquisition was also carried out in the Brent Group.
Well 30/11-15 was drilled to a vertical depth of 4620 metres below sea level and was terminated in the Eiriksson Formation in the Lower Jurassic.
Water depth at the site is 106 metres. The well has now been permanently plugged and abandoned.
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.
The Norwegian Petroleum Directorate (NPD) has granted Equinor Energy ASA drilling permit for well 35/11-28 S in production licence 248 C, cf. Section 13 of the Resource Management Regulations.
The Norwegian Petroleum Directorate (NPD) has granted Neptune Energy Norge AS drilling permit for well 35/6-4 A in production licence 929, cf. Section 13 of the Resource Management Regulations.
