HOUSTON -- ATP Oil & Gas (UK) has been awarded operatorship of the undeveloped Blythe gas discovery in the UK southern North Sea.
Britain’s Department of Energy and Climate Change assigned ATP a 50% interest in Blythe, in blocks 48/22b and 48/23a, under the UK’s 25th licensing round. The remaining 50% interest went to Ebor Energy.
The field was discovered in 1966 in 76 ft (23 m) water depth. Gas is contained in a Rotliegend sandstone interval at a subsurface depth of 7,200 ft (2,194 m).
Elsewhere in the southern gas basin, ATP drilled and tested an appraisal well on Kilmar in May, and it is currently drilling a sidetrack into a separate fault block.
On completion of this program, the rig will move to Garrow to drill a second development well, which should come on stream in late 2010.
ATP expects to bring the Kilmar well into production in late 2011 following installation of pipelines.
In the northern North Sea, ATP says that construction of the Octabuoy hull, which will be deployed initially on the Cheviot field, remains on schedule for delivery (along with the topsides) in late 2012. Cheviot is the company’s largest UK development in terms of proved and probable reserves.
