Foinaven oilfield

Foinaven oil field is deepwater oil development approximately 190km west of the Shetland Islands. Together with Schiehallion, Loyal, Solan, Clair and Lancaster fields it forms the area generally termed as the West of Shetland.Field descriptionFoinaven oil field was discovered in October 1990. It is located in blocks 204/19 and 204/24a of the United Kingdom Continental Shelf in a water depth of 400-. Recoverable oil reserves of Foinaven are estimated to be between 250and.Although the location is described as in the continental shelf block, in practise Foinaven is the first development made beyond the actual reach of continental shelf.ProductionThe Foinaven field is operated by BP Exploration in partnership with Marathon Oil. The development of the field was sanctioned in 1994 and the oil production in Foinaven started in November 1997. The phase 1 with 21 wells was completed in 2000. It has the designed oil production capacity of 85000oilbbl/d of oil.Oil is produced by subsea wells via a manifold, which passes through rigid flowlines and then flexible risers into a Floating Production Storage and Offloading system (FPSO). Surface process facilities consist of two parallel oil separation and gas compression trains with a combined liquid handling capacity of 145000oilbbl/d of crude oil and of associated gas.The FPSO, Petrojarl Foinaven, which is operated by Teekay Petrojarl, has an overall length of and an oil storage capacity of 300000oilbbl. It is permanently stationed in the field and the crude oil is exported by shuttle tankers. Oil is exported primarily to the Flotta oil terminal in Orkney with smaller amount is going to Tranmere Oil Terminal on Merseyside.
