Equinor and its licence partners have decided to invest NOK 3 billion in the North Sea Statfjord Ost field to improve recovery by 23 million barrels of oil equivalent. Written notification of material changes to the Plan for Development and Operation Statfjord Ost was submitted to the Ministry of Petroleum and Energy 16.12.2020.
Statfjord Ost is tied back to the Statfjord C platform by pipelines. A total of four new wells will be drilled from existing subsea templates. The project also includes modifications on Statfjord C and a new pipeline for gas lift.
This decision enables an improvement of the recovery factor on Statfjord Ost and gives an important contribution to extending the life of the Statfjord C platform and the Statfjord Ost field towards 2040.
The original oil volume in place on Statfjord Ost was 415 million barrels of oil. The current recovery factor is 56 percent. As a result of this project, the expected recovery factor is increased to 62 percent.
The Statfjord Ost development comprises subsea installations that include three templates. The field is located five kilometres north-east of Statfjord C. The field came on stream in 1994.
