Natural Gas Services Group, Inc.

A Texas-based company that builds, rents, and services large-horsepower natural gas compression equipment for oil and gas producers. Its rental units help lift gas out of wells, mainly in the Permian Basin, and it also sells compressor parts and maintains customer-owned machines. Founded in 1998 in Midland, Texas, it grew by buying compressor makers such as Screw Compression Systems in 2004, and it also fields its own SMART and eComp emission-reducing technologies.
