Houston-based Enterprise Products Partners LP said Thursday it plans to expand and extend its Acadian natural gas system in Louisiana to deliver 1.8-2.1 Bcf/d from the Haynesville Shale to the Gulf Coast export market.
As designed, an 80-mile-long pipeline would move gas from a point near Cheneyville, LA, on the Acadian Haynesville Extension (AHE), to third-party interconnects near Gillis, LA. The pipe would link to multiple pipelines serving liquefied natural gas (LNG) export facilities in South Louisiana and southeastern Texas. The Gillis Lateral would have 1 Bcf/d capacity.
In aggregate, Enterprise noted, the LNG export market for the region includes design send-out capacity currently operating or under construction of around 15 Bcf/d.
“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 Enterprise general partner CEO A.J. “Jim” Teague. “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.”
As part of the project, Enterprise also plans to increase capacity on AHE by adding horsepower at the Mansfield compressor station in DeSoto Parish, LA. The project, supported by long-term customer contracts, is expected to begin service in mid-2021.
The Legacy Acadian and Haynesville Extension pipelines are part of the Acadian Gas Pipeline System, which comprises 1,300 miles of natural gas pipelines, Enterprise noted. The system links supply in Louisiana and from the Gulf of Mexico with local distribution companies, electric utility plants and industrial customers primarily in the Baton Rouge/New Orleans/Mississippi River corridor area.
Enterprise’s 357-mile Haynesville Gathering System, which has been gathering volumes in the region since the shale play began to prove its production prowess, today as 1.3 Bcf/d of capacity and can treat up to 810 MMcf/d.
During 2Q2019, Enterprise reported its gas pipeline volumes topped previous records to reach 14.5 trillion Btu/d from 13.7 trillion Btu/d in 2Q2018, while natural gas liquids fractionation volumes climbed to 1 million b/d from 927,000 b/d. In the fee-based gas processing business, volumes increased to a record 5.2 Bcf/d from 4.6 Bcf/d.
