Abstract
A method of controlling a pumping stage of a fracturing fleet at a wellsite with a set of diesel pumps and at least one electric pump to reduce the total operating cost by decreasing the flowrate to the pump units with the higher operating cost and increasing the flowrate to the pump units with the lower operating costs. An optimization process on a computer system communicatively connected to the plurality of pumping units can communicate a first interim setpoint to each pumping unit. The optimization process can calculate an operating cost for the diesel frac pumps based on sensor measurements of pressure, flowrate, and motor speed. The optimization process can calculate an operating cost for the electric frac pumps based on the measured power usage and cost of the power. The optimization process can lower the operating cost of fracturing fleet below a threshold operating cost value.
