Associated gas production in the Bakken Shale continues to increase and, with more NGL pipeline capacity coming online and a new option on the horizon, there’s a gunfight brewing between two of the U.S.’s largest midstreamers. At one end of a dusty Wild West street stands the sheriff in town, ONEOK, which recently completed an expansion of its Elk Creek NGL Pipeline. At the other is a renowned midstreamer from Texas, Kinder Morgan, which is staking a claim in the Rockies by converting its Double H crude oil pipeline to NGL service — renaming it Hiland Express when it does — and planning an NGL header pipeline. As we discuss in today’s RBN blog, Kinder is the first to challenge ONEOK in this space.
