On behalf of the partnership, Equinor has submitted a plan for development and operation (PDO) of the Eirin gas field to the Ministry of Petroleum and Energy.
Recoverable reserves in the field are estimated at 27.6 million barrels of oil equivalent, most of which is gas. The Eirin field, which was discovered in 1978, will be developed as a subsea facility tied to the Gina Krog platform in the North Sea. Total investments are estimated at just over NOK 4 billion (2023 NOK).
Increased gas export from Gina Krog, by exporting gas that was previously injected to improve oil recovery, was an important contribution. At the same time, this brought the need to accelerate projects to extend the field life.
Eirin is a central part of this work, and the project has been matured in record time. Production start-up is expected as early as 2025.
Eirin is a gas field located 250 kilometres west of Stavanger. The field was proven in 1978 and was long part of the Gina Krog field development but was later put on hold and is situated at a depth of approximately 4000 metres. Water depth at the field is approximately 120 metres.
The field will be developed as a subsea facility, which will be adapted and ready for tie-in of future discoveries in the area, including an optional expansion for two to four new wells. The development solution is a subsea template tied back to Gina Krog through a production flowline and an umbilical.
