Williams Partners has reached an agreement with Shell and Nexen to provide deepwater gas gathering services to the Appomattox development, located 80 miles offshore Louisiana, in approximately 2195 meters of water.

Williams Partners will provide offshore gas gathering services to its existing Transco lateral, which will provide transmission services onshore to its Mobile Bay processing facility.

Williams Partners also plans to make modifications to its Main Pass 261 Platform and install an alternate delivery route for customers 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 tie-backs.”
