Patent ID: 7104325

Claim:
A method of consolidating a subterranean zone penetrated by a well bore comprising the steps of: (a) introducing a brine preflush containing a C 12 -C 22 alkyl phosphonate cationic surfactant into said subterranean zone around and adjacent to said well bore; (b) introducing a hardenable resin composition into said subterranean zone around and adjacent to said well bore, said hardenable resin composition comprising a furan liquid resin mixture, a solvent, an organosilane coupling agent and an acid catalyst wherein said furan liquid resin mixture is present in said hardenable resin composition in an amount in the range of from about 20% to about 60% by weigh thereof; (c) introducing a brine overflush containing a C 12 -C 22 alkyl phosphonate cationic surfactant into said subterranean zone to displace the resin composition from the pore space in said subterranean zone; and (d) allowing said hardenable resin composition consolidated.
