Enterprise Products Partners LP on Sept. 19 announced plans to expand and extend 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 a roughly 80-mile pipeline originating near Cheneyville, La., on Enterprise’s Acadian Haynesville Extension to third party interconnects near Gillis, Louisiana, 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 about 15 billion cubic feet per day (Bcf/d). The Gillis Lateral will have a capacity of some 1 Bcf/d.

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 De Soto Parish. When completed, the expansion and extension project will increase the Acadian system’s capability to transport Haynesville natural gas production from 1.8 Bcf/d to 2.1 Bcf/d. 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,” said A.J. Teague, CEO of Enterprise’s general partner. “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 Bcf/d 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 about 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, which has a capacity of about 1.3 Bcf/d and can treat up to 810 million cubic feet per day of natural gas, provides a significant and reliable source of supply for the Acadian system.
