Abstract
Methods treating a subterranean formation including providing a one-step acidizing treatment fluid comprising a first aqueous base fluid, a formation stimulation agent, and a stabilizing emulsion, wherein the stabilizing emulsion is an aqueous external emulsion comprising a second aqueous base fluid, a surfactant, and an aqueous-based surface modification agent; introducing the one-step acidizing treatment fluid into the subterranean formation; contacting the formation stimulation agent with the subterranean formation so as to acidize the subterranean formation and create conductive channels therethrough; and contacting the stabilizing emulsion with the subterranean formation so as to release the aqueous-based surface modification agent and stabilize unconsolidated formation particulates therein.
