摘要： Improved methods of forming fractures containing resilient proppant particle packs which prevent the production of sand and fines with produced fluids and prevent proppant flow-back in a subterranean zone penetrated by a well bore are provided. As the fractures are formed, a liquid hardenable resin component is mixed with a liquid hardening agent component and a liquid rubber component to form a hardenable resin composition. The hardenable resin composition is coated onto dry proppant particles which are suspended in the fracturing fluid and placed in the fractures. The hardenable resin composition on the resin composition coated proppant particles is allowed to harden and consolidate the proppant particles into high strength resilient permeable packs.

摘要： 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.
