    Natural Gas Pipelines & Services

  • Home
  • Operations
  • Natural Gas Pipelines & Services
  • Our Natural Gas Pipelines & Services business segment includes gas pipeline systems that provide for the gathering and transportation of natural gas in Colorado, Louisiana, New Mexico, Texas and Wyoming. We lease underground salt dome natural gas storage facilities located in Texas and Louisiana and own an underground salt dome storage cavern in Texas, all of which are important to our natural gas pipeline operations.

    Our onshore natural gas pipelines receive natural gas from producers, other pipelines or shippers at the wellhead or through system interconnects and redeliver the natural gas to processing facilities, local gas distributors, industrial or municipal customers, storage facilities or to other onshore pipelines.

    This segment also includes our related natural gas marketing activities which generate revenues from the sale and delivery of natural gas to local distribution companies, end-users and others purchased from producers, regional natural gas processing plants and the open market
