Well control at surface


  • High pressure surface well control
  • Open hole and cased hole drill stem testing
  • Top drive or kelly bushing rig capable
  • Wire line / slick line / coiled tubing
  • Well cleanup
  • Well intervention


  • Torque can be transferred through the flow head via the top drive
  • Remote activation of flow valve
  • Gate valves utilized to increase reliability

The Full Bore Rotating Control Head is a modular high pressure surface control head which can be configured with up to 4 valves and 3 flow lines. Torque can be transferred to the tubing by rotating from above (top drive) or below (rotary table) while the flow lines remain stationary.
