Stillman is the current owner of Stillman Enterprises with over 10 years experience building and operating sand mines. He is credited to be the first to use basin sand in the Eagle Ford basin. Notable achievements in his career include him discovering his Permian Basin mine in early 2016 and had acreage in the Monahans, Seminole, as well as the Big Springs areas. Subsequently he sold the Monahans property to Preferred Sands. In the Eagle Ford, Stillman opened his first sand plant in early 2016, expanded to a second plan in early 2017, a 3rd plant in late 2017, and more recently a 4th plant in April of 2019. Stillman’s business philosophy is to be the lowest provider of frac sand to the well head.
