Shell has reported that the Appomattox semisubmersible production platform has departed Ingleside, Texas, and is on its way to its final location in the Gulf of Mexico.
Sanctioned in July 2015, Appomattox is 80 mi (129 km) offshore Louisiana, in approximately 7,200 ft (2,195 m) of water.
The development initially will produce from the Appomattox and Vicksburg fields and will consist of a semisubmersible, four-column production host platform, a subsea system featuring six drill centers, 15 producing wells, and five water injection wells.
The platform and the Appomattox and Vicksburg fields will be owned by Shell (79%) and Nexen Petroleum Offshore U.S.A. Inc. (21%), a wholly owned subsidiary of CNOOC Ltd.
Production is expected to begin by the end of 2019. At peak it should produce 175,000 boe/d.
According to Shell, the Appomattox project will cost 30% less than originally expected when sanctioned.
