Abstract: A method and system for increasing fracture conductivity. A slurry, of a solid particulate freely dispersed in fluid spaces around macrostructures suspended in a carrier fluid, is injected into a fracture, the solid particulate is aggregated in the fracture to form clusters, and the pressure reduced to prop the fracture open on the clusters and form interconnected, hydraulically conductive channels between the clusters. The system comprises a subterranean formation, a treatment slurry stage disposed in a wellbore penetrating the formation, and a pump system to inject the treatment fluid stage into a fracture.
