ABSTRACT:
A subterranean hydrocarbon-bearing formation is hydraulically fractured using a crosslinked polymer gel as a fracturing fluid. The gel comprises a high molecular weight, water-soluble, carboxylate-containing polymer and a chromic carboxylate complex crosslinking agent. The gel components are premixed at the surface and injected into a wellbore in fluid communication with the formation at a pressure sufficient to hydraulically fracture the formation.
