US Patent 9816365 Fracturing treatments in subterranean formations using reducible materials

A method of servicing a wellbore in a subterranean formation comprising placing in the wellbore and/or subterranean formation a pad fluid and forming a fracture in the subterranean formation. Next, a first slurry fluid may be placed into the fracture in the subterranean formation. The first slurry fluid may comprise a reducible material and a first particulate material. Next, a second slurry fluid and a spacer fluid may be placed into the fracture in the subterranean formation in an alternating sequence. The second slurry fluid may comprise a second particulate material. Then, the fracture is allowed to close and the fluids are allowed to break. Finally, the reducible materials degrade, to form a particulate-laden proppant pack (PLPP).
