HOUSTON, Oct. 28 -- Enterprise Products Partners LP and Duncan Energy Partners LP announced plans to extend their jointly owned Acadian Gas LLC subsidiary’s Louisiana intrastate natural gas pipeline system into northwest Louisiana. The expansion will provide producers in the Haynesville shale access to nine interstate pipelines (Florida Gas, Texas Eastern, Transco, Sonat, Columbia Gulf, Trunkline, ANR, Tennessee Gas, and Texas Gas) via Acadian’s existing 1,000-mile south Louisiana network.

The project, dubbed the Haynesville Extension, will have capacity to move 1.4 bcfd throught 249 miles of 36-in. and 30-in. OD pipeline connecting to both Acadian’s system and its affiliated Cypress Gas Pipeline. Acadian will build to new compressor station totaling 67,000 hp as part of the project. Additional long-term commitments could boost capacity to 2 bcfd. Enterprise expects the Haynesville Extension to enter service in September 2011.

The current Acadian system has access to more than 150 end-use markets between Baton Rouge and New Orleans, a rapid-cycle salt dome storage cavern, and the Henry Hub. The Haynesville Extension will intersect with Acadian in Pointe Coupee and Assumption Parishes and with the Cypress system in Point Coupee and West Baton Rouge. Initial upstream connections will include nine Haynesville shale locations in DeSoto and Red River Parishes.

Regency Energy Partners LP, Alinda Capital Partners LLC, and GE Energy Financial Services announced plans in September to construct a $47 million pipeline extension of the Haynesville Expansion Project (HEP) in North Louisiana to increase capacity on the Regency Intrastate Gas System (RIGS). The extension, called the Red River Lateral, will add 100,000 MMbtu/day of capacity to the current project, bringing the total capacity to about 1.2 bcfd. Regency described the Red River Lateral as the first of several opportunities to extend the HEP (OGJ Online, Sept. 14, 2009).

Energy Transfer Partners LP also in September entered into a 10-year contract with a shipper to transport 300 MMcfd of gas on its Tiger Pipeline system, bringing total capacity commitments on the proposed line to not less than 1.8 bcfd. ETP said the new volume commitment further demonstrated the need for additional pipeline capacity out of the Haynesville shale. Pending necessary regulatory approvals, ETP intends to start construction of the line by June 2010 and have it in service in the first half of 2011 (OGJ Online, Sept. 10, 2009).
