CALGARY, Canada -- Antrim Energy has submitted a field development plan (FDP) for Phase I of the Causeway field to the UK Department of Energy and Climate Change (DECC).

The FDP, which plans production through a subsea tieback to the Dunlin platform, is for the eastern area of the Causeway field only, and is the first phase of what is anticipated to be several phases of development of the field.

Phase I is anticipated to initially produce 15,000 b/d of oil, accessing approximately 7.3 MMbbl of oil (net 4.8 million) from the east Causeway area. Subsequent phases will access additional reserves in the central and western areas of the Causeway field.

Phase I will involve the subsea completion and tie back of one producer and one pressure maintenance well. The production well, 211/23d-17z, previously tested up to 14,500 b/d of light oil (32º API) from two test intervals totaling 230 ft (70 m) within a 1,177 ft (359 m) net pay interval (measured depth). The well also penetrated an additional section in an adjacent fault block which tested up to 8,100 b/d of oil from a previously drilled well.

Well 211/23d-18 will serve as the pressure maintenance well, with a second production well anticipated one year after first production. The production and injection wells will be tied back 9 km (5.6 mi) subsea to the Dunlin processing facilities to allow crude oil delivery to the Sullom Voe terminal through the Brent pipeline system. The design includes provision for expansion for the further development phases.

Approval of the Causeway FDP is anticipated during 2009.
