A method of forming a temporary or permanent plug or seal in a wellbore or in one or more subterranean formations penetrated by the wellbore comprising the steps of: a) placing a composition comprising a polymerizable resin, optionally, a polar organic diluent, an oil soluble acid catalyst capable of causing polymerization of the resin at formation temperatures, and 10 to 70% by volume rubber or latex added in said subterranean formations or in said well bore at a desired location therein, and thereafter permitting the furan, rubber system to set, thereby forming in said location a plug or seal which consists of a furan resin/rubber composite.
