Chevron North Sea (CNSL) has made the final investment decision (FID) to advance the first phase of the Captain Enhanced Oil Recovery (EOR) project in the UK North Sea.
The project follows multiple EOR pilot programmes at Captain, and is expected to improve the combined recovery rate from the field by leveraging polymer technology.
Stage 1 of the EOR project is an expansion within the existing Captain platform area of the field and will feature up to six long-reach horizontal injection wells.
Chevron Upstream Europe managing director Greta Lydecker said: “Sanctioning Stage 1 EOR at Captain is an important milestone in the development of the technology, which we believe will improve the recovery rate from older fields and help extend the life of assets.
“The application of advanced EOR technology in the North Sea supports the UK Government’s strategy of maximising economic recovery (MER UK) of its offshore energy resource, and this is in direct alignment with Chevron Upstream’s strategy of extracting value from our existing asset base.”
Discovered in 1977, the Captain field is situated in Block 13/22a on the edge of the outer Moray Firth. It started commercial production in March 1997 through horizontal drilling and deploying down-hole pumps.
