Abstract

See full text

A persulfate compound activated by a strong base is used for low-temperature breaking of fluids viscosified with one or more water-soluble synthetic polymers, wherein the water-soluble synthetic polymers are selected from the group consisting of polyacrylamides, copolymers of polyacrylamide, derivatives of polyacrylamide or of copolymers of polyacrylamide, and any combination thereof. The breaker system can be used in an oilfield or pipeline application where such a synthetic polymer, a multi-chain polysaccharide, or combination thereof may be present in a fluid. It is particularly useful at low temperatures of less than 100° F.
