UK oil and gas firm BG Group has started producing first oil from the Knarr field in the Norwegian North Sea.
BG Group operates the field, which was discovered in 2008, with a 45% working interest.
Idemitsu Petroleum Norge and Wintershall Norge own 25% and 20% stakes respectively. DEA Norge owns the remaining 10% interest.
The field was drilled using the Petrojarl Knarr floating production, storage and offloading vessel (FPSO), which has a production capacity of 63,000 barrels of oil equivalent per day, and a storage capacity of 800,000 barrels.
The Knarr field is anticipated to remain in production for about 10 years, generating an estimated 80 million barrels of oil equivalent.
The plan for Knarr is the drilling of nine development wells that include four production wells; two at Knarr central and two at Knarr West. The other five wells will be water injectors.
The production wells will be drilled from two drill centres located at water depths of 1,345ft. Oil and gas will be produced via pressure maintenance by water injection.
The produced oil will be exported from the FPSO through shuttle tankers. Gas will be transported through a new 110km long, 12in diameter pipeline to the St Fergus gas terminal, via the Far North Liquids and Associated Gas pipeline system.
