Equinor Energy AS received consent from the Norwegian Petroleum Directorate to use new pipelines for gas lift to improve recovery in Statfjord Øst field in the Tampen area in the North Sea, 7 km northeast of Statfjord field (OGJ Online, Dec. 23, 2020).
The project mainly consists of a new gas lift pipeline from Statfjord C to existing subsea templates and re-drilling of wells to new locations, completed with gas lift. Equinor estimates that the project will increase recoverable resources by 3.1 million std cu m of oil and 0.8 billion std cu m of gas. Current recoverable reserve estimates are 40.8 million std cu m oil and 5.6 billion std cu m gas.
Total investment for the project is estimated at 3.7 billion kroner. Startup of the new gas lift system is expected to start soon.
Statfjord Øst lies in production licenses 037 and 089 in 150-190 m of water and produces oil from Middle Jurassic sandstone in the Brent Group. The field includes two subsea templates for production and one for water injection. Production is transported via pipeline to Statfjord C for processing, storage, and export. Two production wells have also been drilled from Statfjord C, and the field came on stream in 1994.
Equinor is operator at Statfjord Øst (43.25%) with partners Petoro AS (30%), Vår Energi ASA (20.55%), Inpex Idemitsu Norge AS (4.8%), and Wintershall Dea Norge AS (1.4%).
