Abstract

Methods including preparing a treatment fluid comprising an aqueous base fluid, a gelling agent, and crosslinkable proppant particulates comprising proppant particulates having covalently grafted thereon a boronic acid functional group; crosslinking the crosslinkable proppant particulates with the gelling agent, thereby suspending the crosslinkable proppant particulates in the treatment fluid; introducing the treatment fluid into a subterranean formation having at least one fracture therein; and placing the crosslinkable proppant particulates into the at least one fracture to form a proppant pack therein.
