ONEOK’s WesTex Transmission, L.L.C. (OWT) system is an intrastate pipeline system operating within Texas. OWT offers both intrastate and NGPA 311 transmission services.

The transmission system consists of approximately 2,217 miles of pipeline of various sizes up to 24 inches in diameter. It operates at pressures up to 1,200 psig and has a peak day capacity of 777 MMcf per day. The pipeline is connected to major natural gas producing areas in the Texas Panhandle, Waha Hub and Permian Basin. OWT transports natural gas between Mid-Continent and Waha pipelines.

In Texas, we are connected to the major natural gas producing areas in the Texas panhandle and the Permian Basin, which provides for natural gas to be moved between the Mid-Continent region and the Waha Hub, where other pipelines may be accessed for transportation east to the Houston Ship Channel and west to the California market.

OWT pipeline system is connected to ONEOK’s Texas Gas Storage facility at Loop, Texas, 20 processing plants, 20 interstate pipeline interconnections and 4 intrastate pipeline interconnections.

The Roadrunner Gas Transmission Pipeline transports up to 640 million cubic feet per day (MMcf/d) of natural gas, with up to 570 MMcf/d transported to Mexico’s growing markets.

The bidirectional pipeline extends from ONEOK Partners’ ONEOK WesTex Transmission natural gas pipeline system at Coyanosa, Texas, to an international border-crossing connection at the U.S. and Mexico border near San Elizario, Texas, where it connects with Fermaca’s Tarahumara Gas Pipeline. 

Mid Continent Market Center, L.L.C. (MCMC) is a 204-mile intrastate pipeline system primarily located in Kingman, Sedgwick and Butler counties in south central Kansas. MCMC offers both intrastate and NGPA 311 transportation services.

Major sources of gas supply for MCMC are the Pioneer Resources’ Spivey plant, Panhandle Eastern Pipeline Company and Southern Star Central Gas Pipeline, Inc. pipeline interconnects.

Markets served include several Wichita, Kansas-area industrial customers and distribution customers. The pipeline operates between 500 and 600 psig. MCMC has two mainline compressor stations, Haysville and Colwich, with a combined total 8,000 horsepower.

MCMC has two storage facilities: Brehm and Konold. Brehm Storage has 1.989 Bcf of working capacity, 1,230 horsepower of compression and the ability to deliver up to 35 MMcf per day and inject up to 20 MMcf per day. Konold Storage has 0.7 Bcf of working capacity, 720 horsepower of compression and the ability to deliver and inject up to 10 MMcf per day.
