Williams Cos. Inc. is set to provide a range of midstream services for the Shenandoah development offshore Louisiana in the central Gulf of Mexico.

The Tulsa, Okla.-based pipeline operator said June 16 it had recently reached an export agreement for Shenandoah with Beacon Offshore Energy Development LLC and its co-owner ShenHai LLC, a subsidiary of Navitas Petroleum, through Williams’ Discovery infrastructure.

Located 160 miles off the coast of Louisiana in the Walker Ridge area of the U.S. Gulf, Shenandoah was originally discovered by Anadarko Petroleum in 2009. Since then, the project has changed hands several times, most recently through the sale of LLOG Exploration Co. LLC’s stake in the development to Beacon last year.

Shenandoah is expected to come online by late 2024. As part of its agreement, Williams will provide offshore natural gas gathering and transportation services and onshore natural gas processing services to the Shenandoah development, believed to hold 431 million barrels of oil.

“Our investment in Shenandoah is a strategic expansion of our Gulf of Mexico infrastructure which further strengthens our portfolio of services,” Williams COO Micheal Dunn said in the June 16 release. “We are pleased to provide the entire spectrum of midstream capabilities to Beacon that will capture the full value of these important deepwater resources.”

Located in central Louisiana, Williams’ Discovery System consists of the Larose Gas Plant and Paradis Fractionation Plant, as well as 477 miles of offshore gas transmission and gathering pipe and related infrastructure. Approximately 50 employees support the franchise, which is a 60:40 partnership between Williams and DCP Midstream.

In support of the Shenandoah agreement, Williams said it will install a five-mile offshore lateral pipeline build from the Shenandoah platform to Discovery’s existing Keathley Canyon Connector pipeline, and additional onshore processing facilities to handle the expected rich Shenandoah production.
