Independence Contract Drilling, Inc.

A Houston-based contractor that builds and runs a fleet of land drilling rigs for oil and gas producers across the United States. Its rigs, sold under the ShaleDriller brand, are engineered to drill the deep, complex horizontal wells used in shale and tight-oil fields. Founded in 2011 by a group of industry veterans, the company named its rigs ShaleDriller to spotlight their shale focus. A fun quirk: these rigs have a built-in hydraulic "walking" system that lets each one move itself from well to well on a drilling pad without being taken apart.
