The pressure is on to enhance oil and gas well production. Natural Gas Services Group (NGS) manufactures and leases natural gas compressors used to boost oil and gas well production, primarily in non-conventional plays such as coal bed methane, tight gas, and oil and gas shales. The company also provides flare tip burners, ignition systems, and components used to combust waste gases before entering the atmosphere. NGS leases compressors to third parties in Colorado, Kansas, Louisiana, Michigan, New Mexico, Oklahoma, Pennsylvania, Texas, Utah, West Virginia, and Wyoming. In 2012 some 1,756 units of the company's rental fleet of 2,279 compressors were rented out to clients.
