LONDON, Jan. 2 -- Antrim Energy Inc., Calgary, plans to start production from the eastern section of Causeway oil field in the northern North Sea via a subsea, 9-km tieback to the Dunlin platform. It plans to tie back one producer and one pressure maintenance well and will drill a second production well a year after first production begins.
The company will announce a start-up date after the UK Department of Energy and Climate Change (DECC) approves the field development plan (FDP) for the first phase next year. It said it needs favorable economic conditions, including commodity prices and project funding costs, to move ahead with development.
Phase I is expected to produce 15,000 b/d, accessing 7.3 million bbl of oil from the East Causeway area. Subsequent phases will access additional reserves in the central and western areas of Causeway.
"By phasing these developments, the company can minimize the initial capital commitment and can expect to fund subsequent production phases from revenue generated by previous phases, said Antrim Pres. and Chief Executive Stephen Greer. "This is a cautious, conservative approach, well suited to today's uncertain economic climate."
The production well 211/23d-17z previously tested up to 14,500 b/d of 32° oil from two test intervals totaling 230 ft within a 1,177 ft net pay interval (measured depth). "This well also penetrated an additional section in an adjacent fault block, which tested up to 8,100 b/d from a previously drilled well," Antrim said.
Well 211/23d-18 will serve as the pressure maintenance well. From the Dunlin processing facilities, oil will be sent through the Brent pipeline system to the Sullom Voe terminal.
"The design includes provision for expansion for the further development phases," Antrim said.
In the central North Sea, Antrim also expects to file an FDP for its operated Fyne field by mid-2009. Antrim operates Causeway, holding a 65.5% stake.
