Abstract: A method may include monitoring, for two or more well heads of a hydraulic fracturing system, an operation or a state of one or more subsystems of the hydraulic fracturing system. The hydraulic fracturing system may include one or more fracturing rigs, one or more blending equipment, one or more power sources electrically connected to a first subset of the one or more fracturing rigs, or one or more fuel sources fluidly connected to a second subset of the one or more fracturing rigs, and one or more missile valves. The hydraulic fracturing system may further include one or more zipper valves, one or more well head valves, and multiple well heads. The method may further include controlling, based on an operation schedule for the hydraulic fracturing system and based on monitoring the operation or the state, fluid pressures at the two or more well heads for continuous pumping.

Abstract: A method may include monitoring, by a controller, operation of a pump of at least one hydraulic fracturing rig during ramp-up of the pump. Each of the at least one hydraulic fracturing rig may further include an engine and a transmission. The method may further include detecting, by the controller, an issue in the operation of the pump based on the monitoring of the operation and performing an action based on the detecting of the issue.
