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.
Geological information
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 m, with reservoir rocks totalling 58 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 m below sea level and was terminated in the Eiriksson Formation in the Lower Jurassic.
Water depth at the site is 106 m. The well has now been permanently plugged and abandoned.
