Abstract:
The present disclosure generally relates to a system and methods for breaking friction reducers in subterranean formations in-situ during hydraulic fracturing operations. A method of fracturing a subterranean formation is disclosed, including providing a well treating fluid, adding a friction reducer into a water phase of an emulsion, adding a breaker into the water phase, and injecting the well treating fluid into the subterranean formation at a pressure sufficient to fracture the subterranean formation and invert the emulsion and double emulsion, thereby allowing the breaker to break the friction reducer. A friction reducer-breaker system for breaking a friction reducer polymer in-situ is also disclosed, including an oil phase, a water phase including friction reducer polymers and breakers in double emulsion dispersed throughout the water phase, wherein, the emulsion and double emulsion are configured to invert under shear, thereby providing for mixing between the friction reducer polymers and the breakers.

Claim (Index 4):
The method of  claim 1 , wherein the breaker comprises at least one of an instant breaker and a delayed breaker.
