Methods including introducing a pad fluid into a subterranean formation to create or enhance an open fracture at a first treatment interval therein; introducing a treatment fluid into the fracture, wherein the treatment fluid comprises a second base fluid, crushable-proppant particulates (CPPs), and buoyant-proppant particulates (BPPs), and wherein a first specific gravity of the CPPs is at least about 0.3 greater than a second specific gravity of the BPPs; placing the CPPs and the BPPs in the fracture, wherein the CPPs settle to a bottom portion of the fracture and the BPPs neutrally suspend in the treatment fluid in a top portion of the fracture; and reducing the hydraulic pressure, thereby permitting the fracture to close, wherein the CPPs form a crushed-proppant pack in the bottom portion of the fracture and the BPPs form a proppant pack in the top portion of the fracture, thereby forming an arch channel therebetween. |
