Patent
·
OSTI ID:6798095
A process for producing a controlled reduction in viscosity of aqueous gels at elevated temperatures is described wherein t-butyl hydroperoxide is utilized as a chemical breaker. A gel structure having temperature stability properties which are useful for fracturing subterranean formations is described wherein the gel consists of an aqueous liquid, a gelling agent, and t-butyl hydroperoxide. Galactomannin gums are cellulose derivatives, and are examples of water thickeners which can be broken by this chemical. (11 claims)
