Abstract

A fluid composition comprising: (A) a liquid hardenable resin component comprising a resin; and (B) a hardening agent component comprising a hardening agent for the resin; wherein at least one of the resin or the hardening agent comprises a molecule having at least one heavy atom. The substitution of one or more heavy atoms that have a higher atomic weight than the other atoms of the molecule, increases the molecular mass of the resin or hardening agent, and hence, the density of the fluid composition. 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 method of treating a treatment zone of a well, the method comprising:
(A) providing a treatment fluid comprising (i) a resin; and (ii) a hardening agent for the resin; wherein at least one of the resin or the hardening agent comprises a molecule having at least one heavy atom; (B) introducing the treatment fluid into a well bore; and (C) allowing the treatment fluid to form a hardened mass the well bore.

2 . The method according to claim 1 , wherein the heavy atom is a halogen.

3 . The method according to claim 1 , wherein the resin is an epoxy resin.

4 . The method according to claim 2 , wherein the epoxy resin comprises a diglycidyl ether.

5 . (canceled)

6 . The method according to claim 1 , wherein the resin is selected from the group consisting of: 3,3′,5,5′ tetrabromobisphenol A diglycidyl ether; 3,3′,5,5′ tetrachlorobisphenol A diglycidyl ether; 3,3′,5,5′ tetraiodobisphenol A diglycidyl ether; 4,4′-hexafluoroisopropylidenediphenol diglycidyl ether; a halogenated diglycidyl ether of polyhydroxyl phenol; and any combination thereof.

7 . The method 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, N-aminophenyl piperazine, imidazoline, 1,2-diaminocyclohexane, polytheramine, diethyltoluenediamine, 4,4′-diaminodiphenyl methane, methyltetrahydrophthalic anhydride, hexahydrophthalic anhydride, maleic anhydride, polyazelaic polyanhydride, and phthalic anhydride.

8 . (canceled)

9 . (canceled)

10 . The method according to claim 1 , wherein the fluid composition additionally comprises a solvent selected from the group consisting of: polyethelenglycols, polyethyleneglycol ethers, limonene, propylene carbonate, isopariffinic fluids, and heavy aromatic fluids.

11 . (canceled)

12 . The method according to claim 1 , wherein the fluid composition additionally comprises a reactive diluent.

13 . (canceled)

14 . The method according to claim 1 , wherein the treatment fluid further comprises: an accelerator that comprises 2,4,6 tridimethylaminomethylphenol.

15 . (canceled)

16 . (canceled)

17 . The method according to claim 1 , wherein the hardening agent further comprises a silane coupling agent.

18 . (canceled)

19 . The method according to claim 1 , 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.

20 . The method according to claim 1 , further comprising selecting the molecule having at least one heavy atom to help control the density of the treatment fluid.

21 . A method of treating a treatment zone of a well, the method comprising:
(A) providing a treatment fluid comprising (i) a resin; (ii) a hardening agent for the resin; and (iii) a reactive diluent, wherein at least one of the resin, the hardening agent, or the reactive diluent comprises a molecule having at least one heavy atom; (B) introducing the treatment fluid into a well bore; and (C) allowing the treatment fluid to form a hardened mass the well bore.

22 . The method according to claim 21 , wherein the heavy atom is a halogen.

23 . The method according to claim 21 , wherein the resin is an epoxy resin.

24 . (canceled)

25 . (canceled)

26 . (canceled)

27 . (canceled)

28 . (canceled)

29 . (canceled)

30 . (canceled)

31 . (canceled)

32 . The method according to claim 21 , wherein the reactive diluent is selected from the group consisting of: alkyl glycidyl ethers and phenyl glycidyl ethers.

33 . (canceled)

34 . The method according to claim 21 , wherein the treatment fluid further comprises: an accelerator.

35 . (canceled)

36 . (canceled)

37 . The method according to claim 21 , wherein the hardening agent further comprises a silane coupling agent.

38 . (canceled)

39 . (canceled)

40 . The method according to claim 21 , further comprising selecting the molecule having at least one heavy atom to help control the density of the treatment fluid.

41 . (canceled)

42 . A fluid composition comprising: (A) a resin; and (B) a hardening agent for the resin; and (C) a reactive diluent; wherein at least one of the resin, the hardening agent, or the reactive diluent comprises a molecule having at least one heavy atom.
