Patent attributes
A method of controlling a pumping stage of a fracturing fleet at a wellsite with a set of electric frac pumps to deliver fracturing fluids into a target formation at a steady pressure value. An global control process on a computer system communicatively connected to the plurality of pumping units can communicate a unit setpoint to each pumping unit, monitor the sensor measurements, compare the periodic datasets to a target pressure, and modify the fluid output of the pump units to achieve the target pressure during the pumping operation. The global control process can direct at least one pumping unit to deliver a fracturing treatment at a pressure higher or lower than the target pressure in response to changing wellbore environment pressures.
