Methods comprising: (a) introducing a pad fluid into a formation at a rate and pressure sufficient to create or enhance at least one fracture therein, wherein the pad fluid comprises a pad base fluid, micro-proppant particulates, a gas-generating chemical, and an activator, and wherein either the gas-generating chemical or the activator or both are encapsulated; (b) placing the micro-proppant particulates, the gas-generating chemical, and the encapsulated activator into the fracture; (c) releasing the activator from its encapsulation; (d) reacting the gas-generating chemical and the activator in the fracture so as to generate gas and heat, thereby creating or enhancing at least one microfracture therein; (e) introducing a fracturing fluid into the formation, wherein the fracturing fluid comprises a fracturing base fluid and macro-proppant particulates; and (f) placing the macro-proppant particulates into the fracture so as to form a proppant pack therein. |
