Abstract
A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting a first treatment fluid comprising a gas and substantially free of macroscopic particles through a wellbore to initiate a fracture in a subterranean formation; injecting a second treatment fluid comprising proppant and channelant through the wellbore into the fracture; placing the proppant in the fracture in a plurality of proppant clusters forming pillars spaced apart by the channelant; and removing the channelant to form open channels around the pillars for fluid flow from the subterranean formation through the fracture toward the wellbore.
