Aker BP ASA and partners submitted a plan for development and operation (PDO) for Frosk field development to the Norwegian Ministry of Petroleum and Energy.
The field, in an injectite sandstone reservoir in North Sea license PL340 about 25 km southwest of the Alvheim FPSO, will be developed via tieback to existing Bøyla and Alvheim subsea infrastructure. Production is scheduled to start in first-quarter 2023.
Two new production wells will effectively drain the field. The project has matured over the 2 years since test production commenced, and the tieback will fast-track development, the operator said.
An alliance of Aker BP, Odfjell Drilling, and Halliburton will drill and complete the new wells, and an alliance of Aker BP, Subsea 7, and Aker Solutions will execute the subsea workscope.
Total investments will be around NOK 2 billion (about $230 million). Recoverable reserves in Frosk are estimated at around 10 MMboe.
Alvheim field consists of Kneler, Boa, Kameleon, and East Kameleon structures. Viper-Kobra and Gekko structures also reside within the license. The Kobra East and Gekko (KEG) development is expected to come on stream 1 year after Frosk.
Alvheim area also includes satellite fields Bøyla, Vilje, Volund, and Skogul. All are produced via the Alvheim FPSO, which came on stream in June 2008.
When the Alvheim development was originally sanctioned, recoverable resources from the field were estimated at close to 200 million bbl. Since then, more than 500 million bbl have been produced from the area, the operator said.
Aker BP is operator at Frosk (65%) with partners Vår Energi AS (20%) and Lundin Energy Norway AS (15%).
