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
