BP Norge AS has received consent from the Petroleum Safety Authority (PSA) Norway for gas lift at Valhall water injection platform (IP).
Valhall is an oil field in the southern North Sea in 70 metres of water. The field was originally developed with an accommodation platform, a drilling platform and a production platform. In 1996, a wellhead platform (Valhall WP) was installed, with slots for 19 extra wells.
The four platforms are linked by bridges. A water injection platform (IP) was installed centrally on the field in 2003. The flank development consists of two wellhead platforms, one to the north and one to the south of the field. The southern platform came on stream in 2003 and the northern platform in 2004.
According to the PSA, 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.
The PSA has now given BP Norge consent for gas lift at Valhall IP.
