Abstract
An improved method of mixing a fracturing fluid slurry concentrate comprising a hydrophobic solvent base (e.g., diesel No. 2) and a dispersed hydratable polymer (e.g., hydroxypropyl guar) on a real time basis thus continuously producing a fully hydrated fracturing fluid during the actual fracturing of a subterranean earthen formation. Viscosity rise times of less than 5 minutes are achieved in a continuous operation without the use of large volume storage/hydration tanks, employing primarily conventionally necessary pumps.
