Since the start of the Shale Revolution 15 years ago, U.S. NGL production has increased by an extraordinary 260% to more than 6.5 MMb/d. And it’s not just NGL production that’s up sharply. So are exports of NGL purity products, especially LPG (propane and normal butane) and ethane. All that growth — and the growth that’s still to come — wouldn’t be possible without a seemingly non-stop expansion of NGL-related infrastructure. Everything from gas processing plants and NGL pipelines to salt-dome storage, fractionators and export docks. And much of that infrastructure is in the hands of just a few large midstream companies that over the years have developed “well-to-water” NGL networks that enable their owners to collect multiple fees along the NGL value chain. In today’s RBN blog, we discuss highlights from our new Drill Down Report on NGL networks.
