  • Patent number: 8360152
    Abstract: A process and process line is provided for preparing a friction-reduced hydraulic fracturing fluid at a central location which can be readily transported to an oil or gas well in a formation at a well site, comprising: preparing a mixture of polymer and water at the central location by shearing the polymer in the water in a high shear environment to create the friction-reduced hydraulic fracturing fluid; pumping the friction-reduced hydraulic fracturing fluid through a series of pumps and pipelines to the well site; and injecting the hydraulic fracturing fluid into the oil or gas well at a pressure sufficient to cause fracturing of the formation.
