  • Upstream production (gas lift, boil-off / residue gas, natural gas gathering, natural gas liquids, shale, coal bed methane, enhanced oil recovery – CO2 for natural gas injection)
  • Midstream (gas transmission and storage, natural gas gathering, gas injection, fuel gas, natural gas processing – inlet, sales, refrigeration)
  • Downstream processing (petrochemical plant gas-to-liquids, hydrogen production, various other refining applications, cool gas, methanol and ethylene, ammonia, nitric acid, and urea)
  • Power generation through fuel gas.
