  • Breakers containing iron compounds and their methods of use
    Patent number: 9920241
    Abstract: Methods and well treatment fluids for fracturing a subterranean formation penetrated by a well bore are provided, the method comprising 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 an iron-containing breaker compound. The methods can be used to reduce viscosity of well treatment fluids.
