BP Norge received consent from the Petroleum Safety Authority Norway (PSA) for a gas lift at the Valhall IP.
Increased water production is expected as a result of the water injection at Valhall, and gas lift is being performed to maintain stable production from the wells at IP.
Valhall is an oil field in the southern North Sea in 70m of water. The field was originally developed with an accommodation facility, a drilling facility and a production facility. In 1996, a wellhead facility (Valhall WP) was installed, with slots for 19 extra wells.
The four facilities are linked by bridges. A water injection facility was installed centrally on the field in 2003. The flank development consists of two wellhead facilities, one to the north and one to the south of the field. The southern facility came on stream in 2003 and the northern facility in 2004.
