Wellhead Compression

Cobey’s new wellhead gas compressor is designed for ultimate flexibility, high reliability and fast start up.

  • Base unit capable of 2.66 MMSCFD discharging into a 300 PSIG gathering pipeline, 400 PSIG also available
  • Containerized—The fully-assembled, plug-and-play system is enclosed in an easy-to-ship, 40’ ISO container
  • No loose parts or site assembly required, reducing site commissioning time and cost
  • 530 HP EPA Certified Waukesha Rich-Burn gas engine runs on wellhead gas
  • Capable of a wide range of inlet pressures (3-100 PSIG), using an integral inlet gas regulator
  • Integral hydraulic systems to drive all auxiliary systems (pumps and fans), avoiding any need for additional site power
  • Highly customizable to suit individual users and gas conditions
  • On-board control panel with HMI, accessible from the exterior of the container
  • Built in the USA, in the Marcellus-Utica region

Oil-flooded screw compressor benefit vs. comparable reciprocating options:
  • Operational flexibility, without package modification
  • Higher reliability and longer maintenance intervals
  • Lower maintenance costs, fewer consumable parts
  • Higher compression ratio capability in a single-stage body, compared to 3-4 stage reciprocating options
  • Lower noise and higher frequency, easier to mitigate
  • Low vibration and pulsation, requiring simpler foundation design and eliminating dampening
