摘要 |
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.
