Claim 0:
1. A hydraulic fracturing system, comprising:
one or more fracturing rigs;
one or more blending equipment fluidly connected to inlets of the one or more fracturing rigs;
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;
one or more missile valves fluidly connected to outlets of the one or more fracturing rigs;
zipper valves fluidly connected to outlets of the one or more missile valves, the zipper valves including a first zipper valve and a second zipper valve;
one or more well head valves fluidly connected to outlets of the zipper valves;
multiple well heads fluidly connected to outlets of the one or more well head valves; and
a controller, wherein the controller is configured to:
monitor, for two or more well heads of the multiple well heads, an operation or a state of one or more subsystems of the hydraulic fracturing system, and
control, based on an operation schedule for the hydraulic fracturing system, based on one or more of fuel-related information or emissions-related information, and based on monitoring the operation or the state, fluid pressures at the two or more well heads for continuous pumping by opening the second zipper valve before closing the first zipper valve.
