ABSTRACT:
Alkaline earth metal or transition metal peroxides are used as a delayed breaker in alkaline aqueous fluids containing a water soluble hydrophilic polysaccharide polymer hydrated therein. The peroxide is activated by increasing the temperature of the fluid. The invention is particularly useful for the delayed break of hydraulic fracturing fluids containing hydroxypropyl guar polymer.
