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; (ii) a hardening agent for the resin; and (iii) a reactive diluent, wherein at least one of the resin or the reactive diluent comprises a molecule having four to six heavy atoms; wherein the molecule is selected to control a density of the treatment fluid to at least 10 ppg;
(B) introducing the treatment fluid into a well bore; and
(C) allowing the treatment fluid to form a hardened mass in 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 3 , wherein the epoxy resin comprises a diglycidyl ether.

5. The method according to claim 4 , wherein the diglycidyl ether is selected from the group consisting of: a diglycidyl ether of bisphenol A, cyclohexane dimethanol diglycidyl ether, and any combination thereof.

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: an aliphatic amine, an aliphatic tertiary amine, an aromatic amine, a cycloaliphatic amine, a heterocyclic amine, an amido amine, a polyamide, a polyethyl amine, a polyether amine, a polyoxyalkylene amine, a carboxylic anhydride, 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. The method according to claim 1 , wherein the hardening agent component comprises: a diethyltoluenediamine.

9. The method according to claim 1 , wherein the hardening agent is selected from the group consisting of: tetrabromophthalic anhydride; tetrabromobisphenol A; 4,4′-Methylenebis(3-chloro-2,6-diethylaniline); 4,4′-Methylenebis(3-bromo-2,6-diethylaniline); and 4,4′-Methylenebis[2-chloroaniline]; and any combination thereof.

10. The method according to claim 1 , wherein the fluid composition additionally comprises a solvent.

11. The method according to claim 10 , wherein the solvent is selected from the group consisting of: a polyethyleneglycol, a polyethyleneglycol ether, limonene, propylene carbonate, an isopariffinic fluid, and a heavy aromatic fluid.

12. The method according to claim 1 , wherein the reactive diluent is selected from the group consisting of: an alkyl glycidyl ether and a phenyl glycidyl ether.

13. The method according to claim 1 , wherein the reactive diluent is selected from the group consisting of: a halogenated alkyl glycidyl ether and a halogenated phenyl glycidyl ether.

14. The method according to claim 1 , additionally comprising an accelerator selected from the group consisting of: a tertiary amine; 2,4,6 tridimethylaminomethylphenol; and combinations thereof.

15. The method according to claim 1 , additionally comprising a silane coupling agent.

16. The method according to claim 1 , additionally comprising a solid particulate.

17. 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.

18. The method according to claim 1 wherein the resin has a density of at least 14 ppg.

19. The method according to claim 1 wherein the hardened mass has a homogeneous density.

20. The method according to claim 1 wherein the hardened mass is substantially free of a weighting agent.
