Claim 0:
1. A method of modifying a pumping stage of a pumping operation of a fracturing fleet at a wellsite, comprising:
providing a wellbore treatment design and a fracturing fleet at a wellsite, wherein the wellbore treatment design comprises a wellbore treatment blend, a volume of proppant, a designed pumping procedure, or combinations thereof;
receiving, by a global control process executing on a computer system, an operating setpoint for a current stage of the designed pumping procedure, wherein the designed pumping procedure comprises a plurality of sequential stages, and wherein the operating setpoint comprises a target pressure;
communicating, by the global control process, a first unit setpoint to each of a plurality of pump units, wherein the first unit setpoint comprises the target pressure;
pumping, the current stage by the plurality of pump units, a fracturing fluid at a target pressure into a target formation in response to receiving the first unit setpoint;
determining, by the global control process, a second unit setpoint in response to a wellbore pressure change during the current stage;
communicating, by the global control process, the second unit setpoint to at least one of the plurality of pump units; and
pumping, the current stage by the plurality of pump units, the fracturing fluids at the target pressure into the target formation in response to at least one pump unit pumping the fracturing fluids at the second unit setpoint and a remaining portion of the pump units pumping the fracturing fluids at the first unit setpoint, and wherein the second unit setpoint comprises a pressure value greater than or less than the target pressure.
