1. A method comprising:
providing a pressurizable delivery manifold at a well site, wherein the pressurizable delivery manifold is continuously equalized with a piping system, and wherein the pressurizable delivery manifold comprises:
a fluid line comprising a fluid inlet and a fluid outlet;
an equalization line coupled to the fluid inlet via a first piping tee and coupled to the fluid outlet via a second piping tee;
one or more pressure chambers coupled to the equalization line;
for each of the one or more pressure chambers, a separate plug coupled to that pressure chamber; and
for each of the one or more pressure chambers, a separate remote plug valve coupled to that pressure chamber and coupled to the fluid line;
providing a pressurized treatment fluid to the pressurizable delivery manifold;
releasing one or more well stimulation materials into the pressurized treatment fluid to create a payload delivery treatment fluid; and
injecting the payload delivery treatment fluid into at least a portion of a subterranean formation.
