New 80-mile pipeline will push natural gas from Haynesville Shale to south Louisiana LNG market


Enterprise Products Partners L.P. is expanding and extending its Acadian natural gas system to deliver growing volumes of natural gas from the Haynesville Shale to the LNG market in south Louisiana.

The project will include construction of an approximately 80-mile pipeline originating near Cheneyville, on Enterprise’s Acadian Haynesville Extension to third party interconnects near Gillis, including multiple pipelines serving LNG export facilities in South Louisiana and southeast Texas.

In aggregate, the LNG export market for this region includes design send out capacity currently operating or under construction of approximately 15 billion cubic feet per day. The Gillis Lateral will have a capacity of approximately 1 billion cubic feet per day.

As part of the project, Enterprise also plans to increase capacity on the Acadian Haynesville Extension by adding horsepower at its Mansfield compressor station in DeSoto Parish. When completed, the expansion and extension project will increase the Acadian system’s capability to transport Haynesville natural gas production from 1.8 billion cubic feet per day to 2.1 billion cubic feet per day. The project is supported by long-term customer contracts and is expected to begin service in mid-2021.

“The Haynesville region currently produces approximately 11 Bcf/d of natural gas, which is expected to grow to approximately 14 Bcf/d by 2025,” A.J. “Jim” Teague, chief executive officer of Enterprise’s general partner, said in a statement. “The expansion and extension of the Acadian system enhances our capability to link supply to some of the most attractive markets in the U.S. Once this project is completed, our Acadian system will be able to deliver a total of 2.1 billion cubic feet per day of Haynesville production into the LNG market, South Louisiana industrial complex and other interconnects that serve attractive southeastern U.S. markets.”

The Legacy Acadian and Haynesville Extension pipelines are part of the Acadian Gas Pipeline System, which is comprised of approximately 1,300 miles of natural gas pipelines. It links natural gas supplies in Louisiana and offshore Gulf of Mexico with local distribution companies, electric utility plants and industrial customers located primarily in the Baton Rouge/New Orleans/Mississippi River corridor area. Enterprise’s 357-mile Haynesville Gathering System has a capacity of approximately 1.3 billion cubic feet per day and can treat up to 810 million cubic feet per day of natural gas.
