Chevron USA Inc. berencana akan mengembangkan lahan minyak Big Foot di Teluk Mexico dengan dry-tree floating drilling and production facility dalam perairan 5,300 ft.
The company let a contract to KBR Inc. for front-end engineering and design of the topsides of the facility, the hull of which will be an extended tension-leg platform.
Oil and gas processing equipment on the topsides will include inlet separation, gas compression, dehydration and export, oil treatment and export pumping, produced-water treatment, and required utility systems, KBR said. Initial installation will include water injection facilities for reservoir pressure maintenance early in the fieldâ€™s life.
KBR will provide engineering and project management services to develop the process design; specify the required equipment; lay out, modularize, and integrate the decks; perform structural analyses; and provide the electrical power generation and distribution system to support the platform and electrical submersible pumps.
The field, a 2006 discovery, is on Walker Ridge Block 29 about 200 miles from New Orleans and 180 miles offshore. Itâ€™s 35 miles south of Chevronâ€™s Tahiti oil field, where production started in May in 4,100 ft of water from two subsea drill centers tied back to production equipment on a truss spar (OGJ, May 11, 2009, Newsletter).
Production rates havenâ€™t been disclosed.
Chevron, operator, holds 60% working interest in Big Foot. Partners are Statoil Gulf of Mexico LLC and Marubeni Oil & Gas (USA) Inc.
Chevron earlier signed a letter of intent with Enbridge Inc. for a 40-mile, 20-in. OD pipeline to carry Big Foot oil to a connection with existing pipelines (OGJ, Oct. 12, 2009, Newsletter).
