Equinor Energy has successfully concluded the drilling of exploration well 30/11-15 in the North Sea. The drilling was conducted by the 'Deepsea Stavanger' drilling rig, located approximately 25 km southwest of the Oseberg field in the North Sea and 150 km west of Bergen.
Equinor carried out the drilling on behalf of Aker BP, the operator of the production license. Both Equinor and Aker BP hold a 50% ownership interest in the license. This marks the 14th exploration well in production license 035, which was originally awarded in 1969. The Munin discovery was made in 2011, and the plan for development and operation (PDO) was approved in June 2023. Since the Munin discovery, seven additional exploration wells have been drilled in this production license, with three leading to discoveries.
The primary objective of well 30/11-15 was to confirm the presence of petroleum in Lower Jurassic reservoir rocks within the Statfjord Group. The secondary goal was to sample and log previously confirmed petroleum deposits in the Middle Jurassic Brent Group.
During drilling, the well encountered the Statfjord Group at a depth of approximately 382 meters, with reservoir rocks totaling 58 meters and exhibiting poor reservoir quality. Data acquisition activities were conducted.
The well also encountered the Brent Group, with reservoir properties and hydrocarbon columns consistent with expectations. The discovery initially made in well 30/11-8 S was confirmed in 2011. Data acquisition was also carried out in the Brent Group.
Well 30/11-15 reached a vertical depth of 4,620 meters below sea level and was terminated in the Eiriksson Formation in the Lower Jurassic.
The water depth at the drilling site is 106 meters, and the well has been permanently plugged and abandoned.
