HOUSTON – Royal Dutch Shell plc has made the final investment decision to proceed with the Appomattox deepwater development in the Gulf of Mexico. This decision authorizes the construction and installation of Shell’s eighth and largest floating platform in the GoM.
The Appomattox development initially will produce from the Appomattox and Vicksburg fields, with average peak production estimated at 175,000 boe/d.
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.
The Appomattox development host will comprise a semisubmersible, four-column production host platform, a subsea system featuring six drill centers, 15 producing wells, and five water injection wells.
Appomattox is 80 mi (129 km) offshore Louisiana, in approximately 7,200 ft (2,195 m) of water.
The sanctioned project includes capital for the development of 650 MMboe resources at Appomattox and Vicksburg, with start-up estimated around the end of this decade.
The development of Shell’s recent, nearby discoveries at the Gettysburg and Rydberg prospects remains under review. These could become tiebacks to Appomattox, bringing the total estimated discovered resources in the area to more than 800 MMboe.
Shell Pipeline Co. LP also made a final investment decision on the Mattox Pipeline, a 24-in. corridor pipeline to transport crude oil from the Appomattox host to an existing offshore structure in the South Pass area, and then connect onshore through an existing pipeline.
