Abstract:
1. A method of forming one or more fractures in a subterranean zone penetrated by a well bore and consolidating proppant particles therein comprising the steps of: (a) providing proppant particles pre-coated with a coating composition comprising a hardenable organic resin, a silane coupling agent and a gel breaker; (b) preparing or providing a gelled liquid fracturing fluid; (c) pumping the gelled liquid fracturing fluid into the subterranean zone to form the one or more fractures therein; (d) mixing the proppant particles pre-coated with the coating composition with the fracturing fluid pumped in accordance with step (c) whereby the pre-coated proppant particles are suspended therein; (e) when the pre-coated proppant particles reach the one or more fractures, terminating the pumping of the fracturing fluid; and (f) allowing the coating composition on the pre-coated proppant particles to harden by heat and consolidate the proppant particles into one or more permeable packs.
