The U.S. frac sand market has been turned on its head. Over the past three years, demand for the sand used in hydraulic fracturing has more than doubled, dozens of new “local” sand mines have been popping up within the Permian and other fast-growing plays, and frac sand prices have fallen sharply from their 2017 highs. The big changes don’t end there. Exploration and production companies (E&Ps), who traditionally left sand procurement to the pressure pumping companies that complete their wells, are taking a more hands-on approach. And everyone is super-focused on optimizing their “last-mile” frac sand logistics — the delivery of sand by truck, plus unloading and storage of sand at the well site — with an eye toward minimizing completion costs and maximizing productivity. Today, we begin a blog series on the major upheavals rocking the frac sand world in 2019.
