Abstract
Improved methods and compositions for consolidating proppant in subterranean fractures are provided. In certain embodiments, the hardenable resin compositions may be especially suited for consolidating proppant in subterranean fractures having temperatures above about 200° F. Improved methods include providing proppant particles coated with a hardenable resin composition mixed with a gelled liquid fracturing fluid, and introducing the fracturing fluid into a subterranean zone. The fracturing fluid may form one or more fractures in the subterranean zone and deposit the proppant particles coated with the resin composition therein. Thereafter, the hardenable resin composition on the proppant particles is allowed to harden by heat and to consolidate the proppant particles into degradation resistant permeable packs. The hardenable resin composition may include a liquid bisphenol A-epichlorohydrin resin, a 4,4'-diaminodiphenyl sulfone hardening agent, a solvent, a silane coupling agent, and a surfactant. The solvent may include diethylene glycol monomethyl ether or dimethyl sulfoxide.
