The plan calls for a subsea development with three wells to be drilled and linked to production facilities at the nearby Forties Field, which is said to be the largest oil field in the North Sea operated by Apache Corporation.

Apache also operates and holds a 70% working interest in the Baachus development with the remaining 20% interest held by Shell UK. First production is planned for the first half of 2011.

William Transier, chairman, CEO and president of Endeavour, said: “This is the first approval of four field development plans that Endeavour has submitted for review by the UK government, and we are encouraged that the other three projects will be approved over the next 12 months.”
