Abstract (en)
A method and apparatus for rapidly hydrating a hydratable gel comprising the steps of introducing a predetermined amount of the gel into a stream of hydrating fluid, pumping the stream into a high shear rate mixer having a shear rate of at least 25,000 s<-1>, and directing the hydrated fluid away from the mixer means for treatment of a subterranean formation. <IMAGE>
