Abstract
Methods for fracturing a subterranean formation penetrated by a well bore are provided, the method comprising the step of injecting a well treatment fluid into the well bore at a pressure and flow rate sufficient to fracture the subterranean formation, wherein the well treatment fluid comprises one or more iron-containing compounds and one or more booster compounds. The methods can be used to reduce viscosity and to facilitate the decomposition of acrylamide-containing polymers.
