Abstract

A method to reduce the viscosity of viscosified treatment fluids is disclosed herein. The method includes a water soluble polymer as viscosifying agent, preferably a synthetic water soluble polymer, optionally a crosslinker for the water soluble polymer, a breaker system containing an organic peroxide, mixing the viscosified treatment fluid and the breaker composition and allowing the viscosified treatment fluid and the breaker composition to interact whereby the viscosity of the viscosified treatment is reduced. The application of the process in the production of oil and gas is also discussed.
