In one embodiment, the present invention provides a viscosified treatment fluid composition comprising a base fluid, a gelling agent, and a breaker composition that comprises an oxidizing breaker and a breaker activator that comprises a metal and a protein. In another embodiment, the present invention provides a viscosified treatment fluid composition comprising a base fluid, a gelling agent, and a breaker composition that comprises an oxidizing breaker and a breaker activator that comprises iron. In an embodiment, the present invention provides a breaker composition comprising an oxidizing breaker and a breaker activator that comprises a metal and a protein.

Compositions for reducing the viscosity of treatment fluids

Methods of treating a subterranean formation comprising providing a viscosified treatment fluid that comprises a base fluid and a gelling agent, providing a breaker composition that comprises an oxidizing breaker and a breaker activator that comprises a metal and a protein, allowing the viscosified treatment fluid to interact with the breaker composition, treating the subterranean formation with the viscosified treatment fluid, and allowing a viscosity of the viscosified treatment fluid to be reduced. Further, methods of reducing the viscosity of a viscosified treatment fluids and methods of activating oxidizing breakers are also provided.

Methods for reducing the viscosity of treatment fluids

Improved methods for treating and for fracturing subterranean formations and the fluid compositions are provided. The viscosity of a treating fluid containing gelling agents is broken, even at temperatures of about 250&#xb0; F. and lower, utilizing an oxidizing breaker and a reducing sugar to activate the breaker.

Methods and compositions for breaking viscosified fluids

Improved methods for treating and for fracturing subterranean formations and the fluid compositions are provided. A method presented herein is a method of reducing the viscosity of a viscosified treatment fluid that comprises providing a viscosified treatment fluid that comprises a basic fluid and a gelling agent, providing a breaker composition comprising an oxidizing breaker and a breaker activator that comprises a reducing sugar; and allowing the breaker composition and the viscosified treatment fluid to interact so as to reduce the viscosity of the viscosified treatment fluid.
