Matterhorn Express Pipeline Reaches Final Investment Decision

WhiteWater, EnLink Midstream, LLC (NYSE: ENLC), Devon Energy Corp. (NYSE: DVN), and MPLX LP (NYSE: MPLX) have reached a final investment decision to move forward with the construction of the Matterhorn Express Pipeline after having secured sufficient firm transportation agreements with shippers.

The Matterhorn Express Pipeline has been designed to transport up to 2.5 billion cubic feet per day (Bcf/d) of natural gas through approximately 490 miles of 42-inch pipeline from Waha, Texas, to the Katy area near Houston, Texas. Supply for the Matterhorn Express Pipeline will be sourced from multiple upstream connections in the Permian Basin, including direct connections to processing facilities in the Midland Basin through an approximately 75-mile lateral, as well as a direct connection to the 3.2 Bcf/d Agua Blanca Pipeline, a joint venture between WhiteWater and MPLX.

“WhiteWater is excited to partner with EnLink, Devon, and MPLX to develop incremental gas transportation out of the Permian Basin as production continues to grow in West Texas,” said Christer Rundlof, CEO of WhiteWater. “Matterhorn will provide premium market access with superior flexibility for Permian Basin shippers while playing a critical role in minimizing flared volumes.”

The Matterhorn Express Pipeline is expected to be in service in the third quarter of 2024, pending the receipt of customary regulatory and other approvals.
