    摘要: A well treating composition comprising: a gelled carrier; a particulate material; an epoxy resin system including at least one epoxy resin; and a finely-divided hardening agent which, when dissolved, is operable for hardening the epoxy resin. The finely-divided hardening agent is dispersed in the epoxy resin system. A method of treating a subterranean zone located in a well comprising the steps of: (a) preparing the above-described treating composition; (b) injecting the treating composition into the well such that the treating composition is placed in the subterranean zone; and (c) maintaining the finely-divided hardening agent under conditions such that, prior to injecting the treating composition into the well, the finely-divided hardening agent does not substantially dissolve.

    摘要: Methods and compositions are provided for producing a curable resin coated proppant and a crosslinked aqueous gel carrier fluid system. The resin coated proppant and crosslinked aqueous gel carrier fluid system provided may be controllable thinned or "broken" by the addition of a quantity of oxidizing breaker similar to the quantity of oxidizing breaker sufficient to break the carrier fluid in traditional non-resin coated proppant and crosslinked aqueous gel carrier fluid system. A resole resin is the film forming material use to coat the proppant.
