Abstract
Disclosed are methods of treating a subterranean formation having at least one fracture. The methods include providing a thermal thinning resistant treatment fluid comprising an aqueous base fluid, proppant particulates, and a thermally activated suspending agent, wherein the thermally activated suspending agent is hydratable above a threshold temperature. The thermal thinning resistant treatment fluid is introduced into the subterranean formation and exceeds the threshold temperature so as to hydrate the thermally activated suspending agent. Furthermore, the proppant particulates are placed into the at least one fracture.
