Title: METHODS FOR ENHANCING SUSPENSION AND TRANSPORT OF PROPPANT PARTICULATES AND SUBTERRANEAN FORMATION CONDUCTIVITY
Abstract:
Methods including introducing a first particulate-free treatment fluid (first PFTF) into a subterranean formation above the fracture gradient. Alternatingly introducing a first particulate-laden treatment fluid (first PLTF) and a second particulate-laden treatment fluid (second PLTF) into the subterranean formation, wherein the first PLTF comprises nano-particles and degradable particles and the second PLTF comprises proppant particulates, and wherein the alternating introduction causes the proppant particulates in the second PLTF to agglomerate into proppant aggregates being surrounded by the first PLTF. Placing the proppant aggregates into at least one fracture, removing the hydraulic pressure to close the at least one fracture, and degrading the degradable particulates to form at least one channel between adjacent proppant aggregates.
