Abstract

Compositions including a curable resin and organophilically-modified clay for subterranean oil well applications and methods of using the same. A method of treating a subterranean formation including placing in a subterranean formation a curable composition that includes at least one of a curable organic resin and a thermosetting polymer. The curable composition also includes an organophilically-modified clay.

First claim

What is claimed is:

1. A method of treating a subterranean formation, the method comprising:
placing a curable composition in a subterranean formation, wherein the curable composition comprises:
at least one of a curable organic resin and a thermosetting polymer; and
an organophilically-modified clay comprising an organophilic-modification compound or an ion thereof,
wherein the organophilic-modification compound is at least one of a substituted or unsubstituted (C 10 -C 50 ) fatty acid or a salt thereof, a tri- or tetra-(C 1 -C 50 ) hydrocarbylammonium salt, a tri- or tetra-(C 1 -C 50 ) hydrocarbylphosphonium salt, or combinations thereof, and
wherein each tri- or tetra-(C 1 -C 50 ) hydrocarbylammonium salt, and tri- or tetra-(C 1 -C 50 ) hydrocarbylphosphonium salt is independently selected, is substituted or unsubstituted, and is interrupted by 0, 1, 2, or 3 atoms chosen from at least one of —O—, —S—, substituted or unsubstituted —NH—, or combinations thereof.

2. The method of claim 1 , wherein the organophilic-modification compound comprises a (C 10 -C 50 ) fatty acid salt.

3. The method of claim 1 , wherein the organophilic-modification compound comprises magnesium stearate and zinc stearate.

4. The method of claim 1 , wherein the organophilic-modification compound comprises at least one of a tri- or tetra-(C 1 -C 50 ) hydrocarbylammonium salt, a tri- or tetra-(C 1 -C 50 )alkyl- or alkenylphosphonium salt, or a combination thereof.

5. The method of claim 1 , wherein the organophilic-modification compound comprises at least one of a trimethyl stearyl ammonium salt, dodecyltrimethylammonium bromide, hexadecyltrimethylammonium bromide, tetradecyltrimethylammonium bromide, tetraphenylphosphonium bromide, or combinations thereof.

6. The method of claim 1 , wherein the curable composition comprises an amine component that is at least one of diethyltoluenediamine, polyoxypropylene diamine, 2,4,6-tris(dimethylaminomethyl)phenol, or any combination thereof.

7. The method of claim 1 , further comprising curing the curable composition, to provide a cured product of the curable composition, wherein the curing occurs at least partially above-surface.

8. The method of claim 1 , further comprising curing the curable composition, to provide a cured product of the curable composition, wherein the curing occurs at least partially in the subterranean formation.

9. The method of claim 1 , wherein the curable organic resin comprises a diepoxide-substituted phenyl(C 1 -C 10 ) hydrocarbylphenyl, wherein the phenyl and (C 1 -C 10 ) hydrocarbyl are each independently substituted or unsubstituted.

10. The method of claim 1 , wherein the curable organic resin comprises diglycidyl ether of bisphenol A, cyclohexanedimethanol diglycidyl ether, or a combination thereof.

11. The method of claim 1 , wherein the organophilically-modified clay has a density of about 200 kg/m 3 to about 500 kg/m 3 .

12. The method of claim 1 , wherein the organophilically-modified clay has a particle size of about 1 micron to about 500 microns.

13. The method of claim 1 , wherein at least one organophilic-modification compound or an ion thereof is about 10 wt % to about 50 wt % of the at least one organophilically-modified clay.

14. The method of claim 1 , wherein the curable composition has a density of about 200 kg/m 3 to about 3,000 kg/m 3 .

15. The method of claim 1 , wherein the organophilically-modified clay is about 1 wt % to about 20 wt % of the curable composition.

16. The method of claim 1 , wherein the organophilically-modified clay comprises at least one of kaolinite, montmorillonite, illite, and chlorite.

17. The method of claim 1 , further comprising fracturing at least part of the subterranean formation with the curable composition to form at least one subterranean fracture.

18. The method of claim 1 , further comprising cementing or repairing a wellbore in the subterranean formation.

19. A system for performing the method of claim 1 , the system comprising:
a tubular disposed in the subterranean formation; and
a pump configured to pump the curable composition in the subterranean formation through the tubular.

20. A curable composition for treatment of a subterranean formation, composition comprising:
at least one of a curable organic resin and a thermosetting polymer; and
an organophilically-modified clay comprising an organophilic-modification compound or an ion thereof,
wherein the organophilic-modification compound is at least one of a substituted or unsubstituted (C 10 -C 50 ) fatty acid or a salt thereof, a tri- or tetra-(C 1 -C 50 ) hydrocarbylammonium salt, a tri- or tetra-(C 1 -C 50 ) hydrocarbylphosphonium salt, or combinations thereof, and
wherein each tri- or tetra-(C 1 -C 50 ) hydrocarbylammonium salt, and tri- or tetra-(C 1 -C 50 ) hydrocarbylphosphonium salt is independently selected, is substituted or unsubstituted, and is interrupted by 0, 1, 2, or 3 atoms chosen from at least one of —O—, —S—, substituted or unsubstituted —NH—, or combinations thereof.
