A system and method for operating a fleet of pumps for a turbine driven fracturing pump system used in hydraulic fracturing is disclosed. A method of operating a fleet of pumps associated with a hydraulic fracturing system includes receiving a demand Hydraulic Horse Power (HHP) signal. The demand HHP signal may include the Horse Power (HP) required for the hydraulic fracturing system to operate and may include consideration for frictional and other losses. The method further includes operating all available pump units at a percentage of rating below Maximum Continuous Power (MCP) level, based on the demand HHP signal. Furthermore, the method may include receiving a signal for loss of power from one or more pump units. The method further includes operating one or more units at MCP level and operating one or more units at Maximum Intermittent Power (MIP) level to meet the demand HHP signal.

Methods, systems, and controllers for detecting and mitigating well screen outs may include a controller configured to operate a fracturing pump to supply fluid at a discharge rate to a wellhead at a fracturing well site. The controller may also operate a blender positioned to deliver a blend of proppant and fluid to the fracturing pump. The controller may compare a fluid pressure increase rate to a preselected increase rate indicative of a potential well screen out. The controller may incrementally decrease the discharge rate of the fracturing pump and a flow rate of a blender when the fluid pressure increase rate of the wellhead exceeds the preselected increase rate and the fluid pressure is within a preselected percentage of a maximum wellhead pressure until the fluid pressure of the fluid supplied to the wellhead is stabilized.

Methods for detection and mitigation of well screen out

A system and method of enhancing operation of hydraulic fracturing equipment at a hydraulic fracturing wellsite may include determining if a hydraulic fracturing stage profiles are available for use for hydraulic fracturing equipment at a wellsite.

The method may include, in response to an amendment of one of the hydraulic fracturing stage profiles, prompting acceptance of the amended hydraulic fracturing stage profile as the current hydraulic fracturing stage profile for use in association with the controller. The method may include, when a hydraulic fracturing stage profile is not available, prompting configuration of hydraulic fracturing pumping stage parameters for the current hydraulic fracturing stage profile. The method may include storing the current hydraulic fracturing stage profile as the previous hydraulic fracturing stage profile in association with the controller.
