ABSTRACT:
An aqueous fluid having a viscosity greater than the viscosity of water is contacted with a water soluble material for a time and at a temperature sufficient to reduce the viscosity of the aqueous fluid to a value which is less than about 10 percent of the initial viscosity of the aqueous fluid. The water soluble material is an alkali metal peroxide or a combination of an alkali metal peroxide and a transition metal-containing compound.
