13. A method of hydraulic fracturing a plurality of wells, comprising:
alternating application of a constant pressure of fracturing fluid to a plurality of
wellheads by opening and closing at least one switching valve to create a pulsed pressure wave in each well associated with the plurality of wellheads for fracturing a subterranean formation associated with each well while outputting the fracturing fluid from a pump at a constant rate into each well.
