Abstract
The present invention relates to fracturing fluids of the type used in well bore operations and particularly to a method for producing a gradual reduction in the viscosity of a fracturing fluid through the use of slightly water soluble, organic peroxides incorporated in the viscous fluid. The breaker is effective at controlling the rate of viscosity reduction at low temperature and alkaline pH where other chelated metal catalyst fail.
