  • Cement head system and method for operating a cement head system
    Patent number: 10221647
    Abstract: A cement head system for wellbores and method for maintaining dynamic fluid flow therethrough, wherein a base station wirelessly drives a control sequence to (1) open cement slurry valves to actuate external visual valve indicators, (2) open upper and lower safety valves, to actuate external visual safety valve indicators, (3) open a lower release chamber to actuate an external chamber visual indicator and to release a plug that triggers an external flipper visual indicator, (4) reset the external flipper visual indicator, (5) open an upper release chamber to actuate an external chamber visual indicator and to release a plug that triggers the external flipper visual indicator; and (6) open and close a release mechanism for each of the upper and lower chamber while pumping a flush fluid through the cement head. Each valve, the release mechanisms and flipper have a controller controlled by the base station.
