Equinor has been granted consent by the Norwegian offshore safety regulator, Petroleum Safety Authority Norway (PSA), to utilize the COSL Promoter, a semi-submersible rig owned by COSL Drilling. The approval is for drilling two observation wells at the Statfjord satellites area, specifically related to the Statfjord North field.

Situated 17 kilometers north of the Statfjord field in the northern part of the North Sea, Statfjord Nord operates at water depths ranging from 250 to 290 meters. The field's development, approved in 1990 with production commencing in 1995, involves two production templates and one water injection template tied back to the Statfjord C platform.

The broader Statfjord field, discovered in 1974 on the border between the Norwegian and British sectors, comprises three production platforms: Statfjord A, Statfjord B, and Statfjord C. Equinor's Statfjord Nord, along with Statfjord Øst and Sygna, serves as satellite fields connected to the Statfjord C platform. Notably, Statfjord Øst is jointly located in production licenses 037 in block 33/9 (Statfjord area) and 089 in block 34/7 (Snorre area).

The COSL Promoter, constructed in 2012, is a semi-submersible drilling rig engineered for operations in water depths of up to 750 meters.
