Fracturing fluid with encapsulated breaker - Halliburton ...

To accelerate fracturing fluid viscosity reduction, a chemical agent referred to as a "breaker" is added to the fracturing fluid. Breakers operate by severing the backbone chain of the hydrated polymer. It is critical that the viscosity breaking process does not occur before the fracturing process is completed.

Fracturing fluid having a delayed enzyme breaker

The invention is directed toward a ,breaker, system for breaking fluids used to fracture subterranean formations. Specifically, the invention relates to a ,breaker, system comprised of an enzyme component and a pH component. The enzyme component is active at only certain pH levels and, at those levels, is able to break the ,fluid,. The ,fluid, is not initially at a pH level at which the enzyme is active.
