Foinaven oilfield is a deep-water oil development approximately 190 kilometres (120 mi) 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.

It is located at a water depth of 400–600 metres (1,300–2,000 ft),[1] and was the first development made beyond the United Kingdom Continental Shelf.

[2] Oil was produced by subsea wells via a manifold, which passed through rigid flowlines and then flexible risers into a Floating Production Storage and Offloading system (FPSO).

[7] BP and its partners have begun evaluating options to develop the estimated remaining resources of up to a possible 200 million barrels from the Foinaven field and surrounding area.
