Abstract
A system for cementing a borehole with foamed cement includes a gas delivery assembly mounted on a movable support structure, the gas delivery assembly configured to supply a gas to a cement slurry to generate a foamed cement slurry. The gas delivery assembly includes a heating element in thermal communication with a gas supply, a temperature sensor, a pressure sensor, a flow meter, and an automated control valve in fluid communication with the gas supply. The gas delivery assembly also includes a control module including a processing device configured to control a temperature and a flow rate of the gas supplied to the cement slurry based on a desired flow rate and measurements from the temperature sensor, the pressure sensor and the flow meter.
