Abstract:
Compositions and methods of using such compositions to, for example, reduce the viscosity of treatment fluids are provided. In one embodiment, the methods include: providing a treatment fluid including a base fluid, a viscosifier, and a breaker system including a gel stabilizer; a delayed release oxidative breaker; and a delayed release enzyme breaker; and allowing the breaker system to reduce a viscosity of the treatment fluid.
