ABSTRACT:
Methods and compositions useful in treating subterranean formations, and more particularly, breaker compositions that may be useful in treating subterranean formations wherein synthetic polymers are used, are provided. Of the many methods and compositions provided herein, one composition comprises a source of hydrogen peroxide and an activator. One method comprises providing a polymer breaker composition comprising a source of hydrogen peroxide and an activator; introducing the polymer breaker composition into a well bore which penetrates a subterranean formation; allowing the activator to activate the source of hydrogen peroxide to create an oxidizing species; and allowing the oxidizing species to break synthetic polymers present in the subterranean formation.
