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.
Claims20
A method for controlling one or more frac pumps of a fracturing spread, the method comprising:
- 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;
- and
- 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.
A non-transitory, computer-readable medium having instructions stored thereon that are executable by a processor to perform operations comprising:
- determining a total rate setpoint for a fracturing spread configured to hydraulically fracture a subsurface formation, wherein the fracturing spread includes one or more frac pumps;
- identifying one or more target pumps from the one or more frac pumps, wherein a total pump rate of the one or more target pumps is adjusted to achieve the total rate setpoint;
- determining a total rate dip for the one or more target pumps;
- identifying one or more trim pumps from the one or more frac pumps, wherein an additional pump rate of the one or more trim pumps compensates for the total dip rate generated by the one or more target pumps;
- activating the one or more target pumps to adjust the total pump rate;
- and
- activating the one or more trim pumps for the additional pump rate to compensate for the total rate dip when the one or more target pumps are activated.
A system comprising:
- one or more frac pumps of a fracturing spread, wherein the fracturing spread is configured to hydraulically fracture a subsurface formation;
- a processor;
- and
- a computer-readable medium having instructions stored thereon that are executable by the processor to cause the processor to,
- determine a total rate setpoint for the fracturing spread;
- identify one or more target pumps from the one or more frac pumps, wherein a total pump rate of the one or more target pumps is adjusted to achieve the total rate setpoint;
- determine a total rate dip for the one or more target pumps;
- identify one or more trim pumps from the one or more frac pumps, wherein an additional pump rate of the one or more trim pumps compensates for the total dip rate generated by the one or more target pumps;
- activate the one or more target pumps to adjust the total pump rate;
- and
- activate the one or more trim pumps for the additional pump rate to compensate for the total rate dip when the one or more target pumps are activated.
