Abstract

A fluid composition comprising: (A) a liquid hardenable resin component comprising an epoxy resin; (B) a hardening agent component comprising a hardening agent for the epoxy resin; (C) an impact modifier component comprising an impact modifier selected to impart an increased impact resistance after hardening of the epoxy resin. A method of treating a treatment zone of a well, the method comprising: introducing the treatment fluid into a well bore; and allowing the treatment fluid to form a hardened mass the well bore.

First claim

What is claimed is:

1 . A fluid composition comprising:
(A) a liquid hardenable resin component comprising an epoxy resin; (B) a hardening agent component comprising a hardening agent for the epoxy resin; and (C) an impact modifier component comprising an impact modifier selected to impart an increased impact resistance after hardening of the epoxy resin.

2 . The composition according to claim 2 , wherein the epoxy resin comprises a diglycidyl ether functionalized molecule or a multifunctional glycidyl ether molecule.

3 . The composition according to claim 2 , wherein the diglycidyl ether is selected from the group consisting of: a diglycidyl ether of bisphenol A, optionally blended with butyl glycidyl ether, cyclohexane dimethanol diglycidyl ether, and any combination thereof.

4 . The composition according to claim 1 , wherein the hardening agent is selected from the group consisting of: aliphatic amines, aliphatic tertiary amines, aromatic amines, cycloaliphatic amines, heterocyclic amines, amido amines, polyamides, polyethyl amines, polyether amines, polyoxyalkylene amines, carboxylic anhydrides, triethylenetetraamine, ethylene diamine, N-cocoalkyltrimethylene, isophorone diamine, Naminophenyl piperazine, imidazoline, 1,2-diaminocyclohexane, polytheramine, diethyltoluenediamine, 4,4′-diaminodiphenyl methane, methyltetrahydrophthalic anhydride, hexahydrophthalic anhydride, maleic anhydride, polyazelaic polyanhydride, and phthalic anhydride.

5 . The composition according to claim 1 , wherein the hardening agent component comprises: diethyltoluenediamine.

6 . The composition according to claim 1 , additionally comprising: an accelerator.

7 . The composition according to claim 6 , wherein the accelerator comprises a tertiary amine.

8 . The composition according to claim 6 , wherein the accelerator comprises: 2,4,6 tridimethylaminomethylphenol.

9 . The composition according to claim 1 , wherein the impact modifier comprises a polyethyleneglycol or polypropylene having a functionality selected from the group consisting of: glycidyl ether, epoxide, carboxylic acid, and anhydride.

10 . The composition according to claim 1 , wherein the impact modifier is selected from the group consisting of: polyethyleneglycol diglycidyl ether, polypropyleneglycol diglycidyl ether, and any combination thereof.

11 . A method of treating a treatment zone of a well, the method comprising:
(A) providing a treatment fluid comprising (i) a liquid hardenable resin component comprising an epoxy resin; (ii) a hardening agent component comprising a hardening agent for the epoxy resin; and (iii) an impact modifier component comprising an impact modifier selected to impart an increased impact resistance after hardening of the epoxy resin; (B) introducing the treatment fluid into a well bore; and (C) allowing the treatment fluid to form a hardened mass the well bore.

12 . The method according to claim 11 , wherein the epoxy resin comprises a diglycidyl ether functionalized molecule or a multifunctional glycidyl ether molecule.

13 . The method according to claim 11 , wherein the diglycidyl ether is selected from the group consisting of: a diglycidyl ether of bisphenol A, optionally blended with butyl glycidyl ether, cyclohexane dimethanol diglycidyl ether, and any combination thereof.

14 . The method according to claim 11 , wherein the hardening agent is selected from the group consisting of: aliphatic amines, aliphatic tertiary amines, aromatic amines, cycloaliphatic amines, heterocyclic amines, amido amines, polyamides, polyethyl amines, polyether amines, polyoxyalkylene amines, carboxylic anhydrides, triethylenetetraamine, ethylene diamine, N-cocoalkyltrimethylene, isophorone diamine, Naminophenyl piperazine, imidazoline, 1,2-diaminocyclohexane, polytheramine, diethyltoluenediamine, 4,4′-diaminodiphenyl methane, methyltetrahydrophthalic anhydride, hexahydrophthalic anhydride, maleic anhydride, polyazelaic polyanhydride, and phthalic anhydride.

15 . The method according to claim 11 , wherein the hardening agent component comprises: diethyltoluenediamine.

16 . The method according to claim 11 , additionally comprising: an accelerator.

17 . (canceled)

18 . The method according to claim 11 , wherein the accelerator comprises: 2,4,6 tridimethylaminomethylphenol.

19 . The method according to claim 11 , wherein the impact modifier comprises a polyethyleneglycol or polypropylene having a functionality selected from the group consisting of: glycidyl ether, epoxide, carboxylic acid, and anhydride.

20 . The method according to claim 11 , wherein the impact modifier is selected from the group consisting of: polyethyleneglycol diglycidyl ether, polypropyleneglycol diglycidyl ether, and any combination thereof.

21 . The method according to claim 11 , wherein the introducing of the treatment fluid is into an annulus between a tubing string in the well bore and a subterranean formation; and wherein the allowing the treatment fluid to form a hardened mass the well bore is within the annulus.
