Use of 3D seismic data is paying off for Mobil Exploration & Producing U.S. Inc. in one of its oldest fields in the Gulf of Mexico.
In the latest example, Mobil found a new field pay in the East Cameron area and tested gas at the highest rate in the field's history.
Mobil's East Cameron 64-11 well, 25 miles southeast of Cameron, La., flowed 33.7 MMcfd and 1,200 b/d of condensate through a 1/3 in. choke with 6,756 psi flowing tubing pressure. The well tested two intervals at 11,689-782 feet in middle Miocene LM-1 sand.
Mobil operates the lease with a 62.5% interest. Conoco Inc. holds a 37.5% interest.
Mobil predecessor Magnolia Petroleum Co. and partners acquired a lease on the tract in 1947, but a state-federal jurisdictional dispute prevented a discovery well from being drilled for 10 years. After a platform and pipeline were installed, production began in 1962.
The East Cameron 64-11 well follows the testing of Mobil-Conoco's East Cameron A-8 well on the same tract last year. Also drilled on the basis of 3D seismic data, A-8 flowed at a field record 4,078 b/d of oil through a 20/64 in. choke. It also flowed 9.4 MMcfd of gas with 6,415 psi flowing tubing pressure.
