HOUSTON, Feb. 11 -- Newfield Exploration Co., Houston, discovered oil and gas in prospects in the UK North Sea and the Gulf of Mexico.
The North Sea find is on its 100%-held Grove prospect on License Area 49/10a in the Southern Gas basin.
The well was drilled to 11,400 ft TD and encountered 120 ft of net gas pay in the Permian Leman and Carboniferous Barren Measures sands. It flowed at a rate of 25 MMcfd of gas and 330 b/d of condensate, constrained by limited equipment capacity.
The well, drilled to appraise a 1971 undeveloped discovery, lies in the six-block Cleaver Bank North section of the 100,000-acre license area. It holds reserves of 75-100 bcf of gas equivalent.
Newfield plans to install production equipment and start production late in 2006.
Newfield made its first deepwater Gulf of Mexico discovery as an operator on its 50%-held Wrigley prospect on Mississippi Canyon Block 506.
Well 1, in 3,700 ft of water, encountered 90 ft of high-quality, gross dry gas pay. A sidetrack, drilled 250 ft updip, found 44 ft of similar quality gross gas pay. The reserves are 55-85 bcf of gas equivalent.
Newfield plans to tie back the well to existing infrastructure and expects first production in mid-2006.
Also in this region, Newfield reported a deepwater discovery on the Anduin prospect, in which it holds a 50% nonoperating interest, on Mississippi Canyon Block 755. The well, in 2,400 ft of water, cut 48 ft of gross oil pay. A sidetrack is planned to define reserve size and development options.
At its La Femme prospect on Mississippi Canyon Block 427, the company drilled a gas well in about 5,800 ft of water. Tests from Well 1 logged about 90 ft of gross hydrocarbon pay.
A second well is planned for mid-2005 to determine field size and commerciality. Newfield is the operator of the prospect, with a 50% working interest.
