Shell selects Williams for Appomattox contract

Offshore staff

TULSA, Oklahoma - Williams Partners has reached an agreement with Shell Offshore Inc. and Nexen Petroleum Offshore USA Inc. to provide deepwater gas gathering services to the Appomattox development.

Williams Partners will provide offshore gas gathering services to its existing Transco lateral, which will provide transmission services onshore to the Mobile Bay processing facility. In addition, it also plans to modify its Main Pass 261 platform and install an alternate delivery route from the platform to the existing Destin Pipeline for transportation to another onshore processing facility.

“We’re pleased to expand our existing infrastructure to serve the growing needs of deepwater producers," said Rory Miller, senior vice president of Williams Partners’ Atlantic-Gulf operating area. "This establishes Williams Partners as the first gas gathering system in a new geographic area with capacity available and opportunities for future tiebacks.”

Located about 80 mi (128 km) offshore Louisiana, Appomattox is in about 7,200 ft (2,194 m) of water. Shell said it is currently the only operator with commercial discoveries in this formation, the Norphlet play, which dates back to the Jurassic period.

Shell announced the final investment decision to advance Appomattox development in the Gulf of Mexico in July 2015. Once completed, it will be home to Shell’s eighth and largest platform in the Gulf of Mexico. The development will initially produce from both the Appomattox and Vicksburg fields, with average peak production estimated to reach about 175,000 boe/d, Shell said.

Operator Shell holds 79% of the Appomattox development. Nexen holds 21%.
