ABSTRACT:
A system and method for using a pneumatic line to automate the launch a cement plug from a cement head. The pneumatic line is in communication with the valves and retaining devices normally found on a typical cement head. The system ensures that the proper sequence of opening and closing valves in combination with the removal of the retaining device is used to safely launch a cement plug from the cement head. The pressure in the single pneumatic line may be varied to launch multiple cement plugs from a cement head. The system may be used to remotely launch a cement plug from a cement head. A wireless remote may be used to regulate the pressure in the pneumatic line to launch cement plugs from the cement head as desired.
