MOBIL WELL YIELDS HEFTY GAS FLOW IN GULF OF MEXICO
Mobil Exploration & Producing U.S. Inc. has gauged the company's biggest Gulf of Mexico gas flow.
Mobil's B-7 directional development well in 180 ft of water on East Cameron Block 286, 72 miles south of Cameron, La., flowed 73 MMcfd of gas and 525 b/d of 50 gravity condensate through a 76/64 in. choke with 2,313 psi flowing tubing pressure from an early Pleistocene interval at a measured depth of 10,320-758 ft.
The well cut 1,362 ft of net pay in 11 sands on the way to a total measured depth of 10,805 ft.
True vertical depth of the interval tested was 9,250 ft, the deepest sand encountered by B-7.
B-7 is the third well in a development drilling program that began in late 1992 from Block 286's B platform after 3D seismic data showed multiple structures below B platform's existing productive interval. The two other wells have not been flow tested.
Mobil E&P U.S. Pres. C.E. Spruell said results of the development program show how new oil field technology is expanding understanding of the gulf s geological complexity, even in areas under development for several decades.
Operator Mobil and Chevron U.S.A. Production Co. each own a 50% interest in East Cameron 286. The partners acquired the block in December 1970 for an $8.9 million bonus and started production there in 1973 from an interval at 5,600 ft through 11 wells connected to the tract's A platform.
Before the B platform drilling program, production from the field was 20 MMcfd.
When all three of B platform's deeper wells go on line in August, Mobil and Chevron expect combined flow of 100 MMcfd of gas and 600 b/d of condensate.
