ABSTRACT:
An aqueous gel containing a retarded crosslinking composition comprising a zirconium salt or chelate and a polyhydroxyl-containing compound and optionally including an aqueous fluid or an alkanol. The gel is useful for fracturing and placing propping agents within a subterranean formation. The gel has a high viscosity in the formation and has pumping characteristics in turbulent flow similar to those of the base gel.
