Claim 15:
16. A method, comprising:
receiving produced water from one or more well sites at a centralized facility via one or produced water pipelines;
receiving sand from one or more sand mines at the centralized facility via one or more sand pipelines;
receiving one or more chemicals at the centralized facility; and
conveying the produced water, the sand, and the chemicals from the centralized facility to one or more fracturing sites via one or more fracturing slurry pipelines and processing equipment of the centralized facility, wherein:
movement of the produced water, the sand, and the one or more chemicals through the one or more fracturing slurry pipelines and the processing equipment passively mixes the produced water, the sand, and the one or more chemicals into a fracturing slurry without using active mixing equipment; and
the processing equipment comprises:
a low-shear addition system to add a friction-reducing additive to the fracturing slurry, wherein the low-shear addition system comprises at least one eductor to disperse the friction-reducing additive into the fracturing slurry.
