Claim Text:
1. A method comprising: providing coated proppant particulates comprising proppant particulates wherein the proppant particulates are coated with a binding agent, wherein the binding agent adheres a gas-generating chemical and a delayed encapsulated activator to the particulates, and wherein the delayed encapsulated activator comprises an activator surrounded by an encapsulating material; suspending the coated proppant particulates having the gas-generating chemical and the delayed encapsulated activator adhered thereto in a treatment fluid; placing the treatment fluid into at least one fracture in a subterranean formation; releasing the activator from its encapsulation within the at least one fracture; and reacting the adhered gas-generating chemical with the released activator so as to produce a gas within the at least one fracture and form a proppant pack therein, the reacting occurring while the gas-generating chemical is still adhered to the binding agent on the coated proppant particulates, wherein the gas acts specifically upon the coated proppant particulates.
