Project Map
The Rocky Mountain Region is fast becoming one of the leading natural gas and NGL producing areas in the United States.

Jonah Gas Gathering
In 2006, Enterprise formed a joint venture with TEPPCO Partners, L.P. to expand the capacity of the Jonah Gas Gathering system. The Phase V expansion project involves the construction of 87 miles of gathering pipelines and the installation of more than 157,000 horsepower. The initiative, which is expected to be completed in the first quarter of 2008, will increase capacity of the Jonah system from 1.5 Bcf/d of natural gas to 2.3 Bcf/d. Ongoing expansion of Jonah Gas Gathering has nearly quadruped capacity of the system since 2001.
Pioneer
During the first quarter of 2008, Enterprise expects to complete construction of a new, state-of-the-art Pioneer cryogenic natural gas processing plant near Opal, Wyoming. The facility will have the capability to process up to 750 million cubic feet per day (MMcf/d) of natural gas and extract up to 35,000 barrels per day (BPD) of natural gas liquids (NGLs) for delivery into the partnership’s Mid-America Pipeline (MAPL) system. The new cryogenic plant will complement an adjacent silica gel processing facility that Enterprise purchased from TEPPCO and doubled natural gas capacity to 600 MMcf/d.
Meeker
To accommodate the increasing natural gas production in the Piceance Basin, Enterprise constructed the Meeker natural gas processing plant in Rio Blanco County, Colorado. Phase I of the facility, which went into service in October of 2007, is designed to process up to 750 MMcf/d of natural gas and extract as much as 35,000 BPD of NGLs. Phase II, which is expected to begin service in mid-2008, will double capacity of the complex to 1.5 Bcf/d and 70,000 BPD. Meeker, along with other components of its midstream network in the Rockies, is supported by long-term agreements with the region’s largest natural gas producers.
MAPL
Key to Enterprise’s growth initiative in the Rockies is the partnership’s MAPL system, which provides an outlet for NGLs extracted at the Meeker and Pioneer facilities. An expansion of the Rocky Mountain portion of the MAPL system, which was completed in October of 2007, added 50,000 BPD of incremental capacity.
Hobbs
Strategically situated at the interconnection of the MAPL and Seminole Pipeline systems, Enterprise’s Hobbs fractionator provides shippers of Rocky Mountain natural gas with the flexibility to access the largest NGL hub at Mont Belvieu Texas, or the high-demand consuming market via the Conway, Kansas Hub. The facility will complement the partnership’s integrated energy value chain by generating fractionation fees that had previously not been recovered because of capacity constraints at Mont Belvieu. Hobbs, which went into service in August of 2007, has the capacity to separate up to 75,000 BPD of products such as propane, butane and ethane.
