Abstract
A method for controlling one or more frac pumps of a fracturing spread. The method comprises adjusting a total pump rate of one or more target pumps of the frac pumps to achieve a total rate setpoint for the frac pumps. The method comprises activating one or more trim pumps for an additional pump rate to compensate for a total rate dip occurring when the total pump rate of the one or more target pumps is adjusted.
Claims8
A method for controlling two or more frac pumps of a fracturing spread, the method comprising:
- obtaining a total rate setpoint for the fracturing spread;
- identifying one or more target pumps of the frac pumps;
- determining a total pump rate adjustment of the one or more target pumps of the frac pumps to achieve the total rate setpoint for the frac pumps;
- determining a total rate dip aggregated across the one or more target pumps associated with the total pump rate adjustment;
- identifying one or more trim pumps of the frac pumps configured to compensate for the total rate dip;
- and
- activating the one or more trim pumps of the frac pumps in response to the aggregated total rate dip, wherein the one or more trim pumps are continuously controlled as the aggregated total rate dip is continuously monitored.
