Natural Gas Services Group, Inc. (NGS) is a U.S.-based company that specializes in providing natural gas compression solutions and equipment to the energy sector. NGS's activities encompass the full lifecycle of natural gas compressors and associated gear, including their design, manufacturing, rental, and sale. A significant portion of its operations centers on the rental of compression units, which cater to small, medium, and large horsepower requirements, primarily supporting unconventional oil and natural gas extraction. As of December 31, 2021, NGS maintained a substantial rental fleet comprising 2,023 natural gas compression units, collectively generating 418,041 horsepower. Beyond rental, NGS is also involved in the engineering, fabrication, and assembly of compressor components, which are then integrated into full compressor units for either rental or direct sale. The company further designs and manufactures its own range of reciprocating compressor frames, cylinders, and various parts. In addition to compression, NGS extends its expertise to flare stacks. It designs, fabricates, sells, installs, and services flare stacks along with their accompanying ignition and control systems. These systems are crucial for the safe, controlled incineration of various gas compounds – such as hydrogen sulfide, carbon dioxide, natural gas, and liquefied petroleum gases – in both onshore and offshore environments. To complement its product offerings, NGS provides comprehensive customer support for its compressor and flare sales, and it also runs an exchange and rebuild program specifically for small horsepower screw compressors. NGS primarily serves a diverse client base within the energy sector, including exploration and production (E&P) companies utilizing compressor units for artificial lift, E&P firms focused on natural gas-weighted production, and various midstream companies. Established in 1998, Natural Gas Services Group, Inc. is headquartered in Midland, Texas.
