Williams takes over Shell’s deepwater gathering pipeline in Gulf of Mexico

Natural gas infrastructure provider Williams has acquired and placed into service the Norphlet deepwater gathering pipeline system, constructed by Shell Offshore and CNOOC Petroleum Offshore.

The 16-inch pipeline extends 54 miles from the Shell-operated Appomattox floating production system at a depth of 7,400 feet to the Transco Main Pass 261A junction platform, located south of Mobile, Alabama.

According to Williams, the acquisition expands the reach of its pipeline network by connecting Williams’ existing Transco offshore pipeline lateral to the Jurassic play in the eastern Gulf of Mexico.

“We are excited to participate in this Jurassic development with Shell and CNOOC,” said Alan Armstrong, president and CEO of Williams. “Shell has exhibited a tremendous history of successful large-scale developments across the Gulf of Mexico and early indications here are for that to continue in this Jurassic play with their additional discoveries.”

The Norphlet system is capable of gathering approximately 261-291 million cubic feet per day of natural gas.

Around half of the pipeline’s contractual capacity is still available for future producer discoveries in the Jurassic play area.
