Assignee: HALLIBURTON ENERGY SERVICES, INC.
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC E  F | IPC E  F

Claim 15:
16. A fracturing fleet system at a wellsite, comprising:
a blender fluidically connected to a manifold;
a plurality of pumping units comprising at least two electric frac pumps fluidically connected to the manifold;
a wellhead connector fluidically connected to the manifold;
an global control process, executing on a computer system, controlling a pumping operation of the fracturing fleet;
wherein the global control process is configured to perform the following:
loading an operating setpoint for an interval of a designed pumping procedure, wherein the operating setpoint comprises a target pressure value, and wherein the designed pumping procedure comprises a plurality of sequential pumping stages;
determining a first unit setpoint and a second unit setpoint, wherein the first unit setpoint is equal to the target pressure value, wherein the second unit setpoint is i) equal to, ii) less than, or iii) greater than the first unit setpoint in response to a probability value indicating that a wellbore pressure is i) equal to, ii) greater than, or iii) less than the target pressure; and
communicating the second unit setpoint to a first electric frac unit and a first unit setpoint to the remaining electric frac units; and
pumping a fracturing treatment into the wellhead connector at the target pressure in response to the first electric frac unit delivering the fracturing treatment at a pressure value i) equal to the target pressure, ii) less than the target pressure, or iii) greater than the target pressure.
