ABSTRACT:
A tertiary amine/persulfate breaker system is disclosed which effects complete breaks of polysaccharide based water-gels or fluids in the ambient temperature range. Induction time may be controlled over wide permissible limits. The invention claims improved compositions and methods, particularly advantageously applied to the treatment and stimulation of shallow oil and gas wells (formation temperatures from about 50.degree. to 125.degree. F.).
