Claim:
1. A method, comprising: placing a downhole completion staging system tool in a wellbore adjacent a subterranean formation; operating the downhole completion staging system tool to establish one or more passages for fluid communication between the wellbore and the subterranean formation in a plurality of wellbore stages spaced along the wellbore; isolating one of the wellbore stages for treatment; injecting an in situ channelization treatment fluid through the wellbore and the one or more passages of the isolated wellbore stage into the subterranean formation to form within a fracture a homogeneous region of continuously uniform distribution of solid particulates and thereafter aggregate the solid particulates to place clusters in the fracture; and repeating the isolation and clusters placement for one or more additional stages wherein the in situ channelization treatment fluid comprises a viscosified carrier fluid, the solid particulates, a breaker, and at least an anchorant, the breaker inducing settling of the solid particulates prior to closure of the fracture.
