Enterprise Extending Acadian Gas Pipeline System in Louisiana

P&GJ Staff Report

Enterprise Products Partners said it is responding to higher demand for natural gas in the growing Gulf Coast LNG market by expanding and extending the Acadian pipeline system and boosting its capacity through upgrades to the Mansfield compressor station. 

Houston-based Enterprise plans to construct an 80-mile, 1-Bcf/d intrastate pipeline originating near Cheneyville, Louisiana, on its Acadian Haynesville Extension to third-party interconnects near Gillis, including multiple pipelines serving LNG export facilities in South Louisiana and southeast Texas. 

The company also plans to increase capacity on the 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 capacity by 300 MMcf/d to 2.1 Bcf/d from 1.8 Bcf/d. The project is supported by long-term customer contracts and is expected to begin service in mid-2021, Enterprise said. 

“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. “Jim” Teague, chief executive officer 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." Teague said. "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 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, which has a capacity of approximately 1.3 Bcf/d and can treat up to 810 MMcf/d of natural gas, provides a significant and reliable source of supply for the Acadian system. 

Enterprise Products assets currently include approximately 50,000 miles of pipelines; 260 million barrels of storage capacity for NGLs, crude oil, petrochemicals and refined products; and 14 Bcf of natural gas storage capacity.
