WBI Energy provides natural gas transportation through approximately 3,800 miles of regulated pipeline systems primarily in the Rocky Mountain and northern Great Plains regions of the United States. 

WBI Energy’s system is strategically located near five natural gas-producing basins, making natural gas supplies readily available to the company’s transportation and storage customers. The system has 14 interconnecting points with other pipeline facilities, allowing for the receipt and/or delivery of natural gas to and from other regions of the country and Canada. WBI Energy owns the largest natural gas storage field in North America, which is adjacent to the Bakken play.
