Abstract
Methods that comprise: providing a carrier fluid comprising a delayed breaker; providing a plurality of proppant aggregates comprising a binder fluid and a filler material; suspending the plurality of proppant aggregates in the carrier fluid; introducing the carrier fluid into the subterranean formation at or above a pressure sufficient to create or enhance at least one fracture, the carrier fluid comprising the plurality of proppant aggregates suspended therein; allowing the carrier fluid to break so as to reduce the viscosity of the carrier fluid; and recovering at least a portion of the carrier fluid from the at least one fracture wherein at least a substantial portion of the plurality of proppant aggregates remains in the at least one fracture so as to create a high porosity propped fracture.
