Our Gathering and Processing segment is an integrated midstream natural gas system that provides the following services to our customers:

• Gathering
• Compression
• Treating
• Processing
• Transportation
• Sales of natural gas, NGLs and condensate.

 

Gloria
The Gloria gathering system provides gathering and compression services through our assets, as well as processing services through third party arrangements. The Gloria system is located in Lafourche, Jefferson, Plaquemines, St. Charles and St. Bernard parishes of Louisiana, gathering natural gas from onshore oil and natural gas wells. The system consists of approximately 110 miles of pipeline and three compressors with a combined capacity of 1,877 horsepower. The design capacity is approximately 90 MMcf/d.

Lafitte
The Lafitte gathering system consists of approximately 40 miles of gathering pipeline, with a design capacity of approximately 71 MMcf/d. The Lafitte system originates onshore in southern Louisiana and terminates in Plaquemines Parish, Louisiana at the Alliance Refinery owned by ConocoPhillips.

Bazor Ridge
The Bazor Ridge gathering and processing system consists of approximately 160 miles of pipeline and three compressor stations with a combined compression capacity of 1,069 horsepower. The system is located in Jasper, Clarke, Wayne and Greene Counties of Mississippi. The system also contains a cryogenic sour natural gas treating and processing plant located in Wayne County, Mississippi with a design capacity of approximately 22 MMcf/d. Our Heidelberg gathering system is also located within the Bazor Ridge area in Jasper County, Mississippi, and has a design capacity of approximately 18 MMcf/d.

In 2010, we built a new eight-inch diameter pipeline consisting of approximately nine miles of pipe, called the Winchester lateral, to serve natural gas wells located in Wayne County, Mississippi. The Winchester lateral allowed us to increase the effective throughput capacity of the Bazor Ridge gathering system by approximately 200% to approximately 25 MMcf/d.

The natural gas supply for our Bazor Ridge system is derived primarily from rich associated natural gas produced from oil wells targeting the mature Upper Smackover formation. Production from the wells drilled in this area is generally stable with relatively modest decline rates.

Quivira
The Quivira gathering system consists of approximately 34 miles of pipeline, with a 12-inch diameter mainline and several laterals ranging in diameter from six to eight inches. The system originates offshore of Iberia and St. Mary Parishes of Louisiana in Eugene Island Block 24 and terminates onshore in St. Mary Parish, Louisiana at a connection with the Burns Point processing plant, a cryogenic processing plant with a design capacity of 160 MMcf/d that is owned and operated by Enterprise. The system has a design capacity of approximately 140 MMcf/d. This system also includes an onshore condensate handling facility at Bayou Sale, Louisiana that is upstream of the Burns Point processing plant.

The Quivira system provides gathering services for natural gas wells and associated natural gas produced from crude oil wells operated by major and independent producers targeting multiple conventional production zones in the shallow waters of the Gulf of Mexico. The natural gas produced from these wells is typically natural gas with condensate.

Offshore Texas
The Offshore Texas system consists of the GIGS and Brazos systems, two parallel systems that provide gathering and dehydration services to natural gas producers in the shallow waters of the Gulf of Mexico region offshore Texas.

The Offshore Texas system consists of approximately 56 miles of pipeline with diameters ranging from six to 16 inches and a design capacity of approximately 100 MMcf/d. Additionally, the Offshore Texas system has two onshore separation and dehydration units, each with a capacity of approximately 40 MMcf/d, that remove water and other impurities from the gathered natural gas before delivering it to our customers. The GIGS system originates offshore of Brazoria County, Texas in Galveston Island Block 343 and connects onshore to the Houston Pipeline system. The Brazos system originates offshore of Brazoria County, Texas in Brazos Block 366 and connects onshore to the Dow Pipeline system.

Alabama
The Alabama Processing system consists of two small skid-mounted treating and processing plants that we refer to, individually, as Atmore and Wildfork. These treating and processing plants are located in Escambia and Monroe Counties of Alabama, respectively, and have design capacities of 3 MMcf/d and 7 MMcf/d, respectively.

The Magnolia gathering system is a Section 311 intrastate pipeline that gathers coalbed methane in Tuscaloosa, Greene, Bibb, Chilton and Hale counties of Alabama and delivers this natural gas to an interconnect with the Transco Pipeline system. The Magnolia system consists of approximately 116 miles of pipeline with small-diameter gathering lines and trunklines ranging from six to 24 inches in diameter and one compressor station with 3,328 horsepower. The Magnolia system has a design capacity of approximately 120 MMcf/d.

The Fayette gathering system is located in Fayette County, Alabama, with a design capacity of approximately 5 MMcf/d.
