Abstract
Methods including introducing a treatment fluid into a subterranean formation having at least one fracture therein, the treatment fluid comprising an aqueous base fluid and brush photopolymerized coated proppant particulates (bPCPPs), and placing the bPCPPs into the at least one fracture to form a proppant pack therein. The bPCPPs comprise proppant modified with a coupling agent photopolymerized to a derivatized hydrophilic polymer, thereby resulting in a brush polymer structure of the derivatized hydrophilic polymer extending from the proppant.
