Patent ID: 8371382

Claim:
A method comprising: providing an aqueous-based fracturing fluid; placing the aqueous-based fracturing fluid into a subterranean formation; placing an erosion agent in the aqueous-based fracturing fluid and/or the subterranean formation; allowing a channel to form within a fracture network in the subterranean formation; providing a plasticity modification fluid that comprises an aqueous fluid and an alkaline embrittlement modification agent; wherein the embrittlement modification agent comprises a base chosen from the group consisting of: an amine; lithium hydroxide; sodium hydroxide; potassium hydroxide; rubidium hydroxide; calcium hydroxide; strontium hydroxide; barium hydroxide; sodium carbonate; lime; and any derivative or combination thereof; placing the plasticity modification fluid into a fracture in the fracture network in the subterranean formation; and embrittling at least one fracture face of the fracture to form an embrittled fracture face.
