Abstract

The present invention includes methods and compositions that include a latex, and at least one of a natural pozzolan or cement kiln dust. An embodiment includes a method comprising: placing a latex composition in a subterranean formation, wherein the latex composition comprises: latex, a component selected from the group consisting of a natural pozzolan, cement kiln dust, and a combination thereof, and water; and allowing the latex composition to set. Another embodiment of the present invention includes a latex composition comprising: latex, a component selected from the group consisting of a natural pozzolan, cement kiln dust, and a combination thereof.

Claims

1. A method comprising:

placing a latex composition in a subterranean formation, wherein the latex composition comprises;

latex,

a component selected from the group consisting of a natural pozzolan, cement kiln dust, and a combination thereof, and

water; and

allowing the latex composition to set.

2. The method of claim 1 wherein the latex comprises a rubber selected from the group consisting of an ethylene-propylene rubber, a styrene-butadiene rubber, a nitrile rubber, a nitrile butadiene rubber, a butyl rubber, a neoprene rubber, a polybutadiene rubber, an acrylonitrile-styrene-butadiene rubber, a polyisoprene rubber, and an AMPS-styrene-butadiene rubber,

3. The method of claim 1 wherein the latex comprises an AMPS-styrene-butadiene rubber.

4. The method of claim 1 wherein the latex composition comprises the natural pozzolan, and wherein the natural pozzolan comprises pumicite.

5. The method of claim 1 wherein the latex composition comprises the cement kiln dust in an amount of about 1% to about 99% by weight of cementitious components in the latex composition.

6. The method of claim 1 wherein the latex composition further comprises an additive selected from the group consisting of fly ash, slag cement, metakaolin, shale, zeolite, a gas, crystalline silica, amorphous silica, fumed silica, a salt, a fiber, a hydratable clay, a microsphere, rice husk ash, lime, and any combination thereof.

7. The method of claim 1 wherein the latex composition further comprises an additive selected from the group consisting of a latex stabilizer, a strength-retrogression additive, a set accelerator, a set retarder, a set accelerator, a weighting agent, a lightweight additive, a gas-generating additive, a mechanical property enhancing additive, a lost-circulation material, a filtration-control additive, a dispersant, a fluid loss control additive, a defoaming agent, a foaming agent, an oil-swellable particle, a water-swellable particle, a thixotropic additive, and any combination thereof.

8. The method of claim 1 wherein the latex composition is foamed.

9. The method of claim 1 wherein allowing the latex composition to set comprises allowing the latex composition to set in an annulus between the subterranean formation and a conduit disposed in the subterranean formation.

10. A method comprising:

placing a latex composition in a subterranean formation, wherein the latex composition comprises;

latex,

a hydraulic cement,

a component selected from the group consisting of a natural pozzolan, and a combination thereof, and

water; and

allowing the latex composition to set.

11. The method of claim 10 wherein the latex comprises an AMPS-styrene-butadiene rubber.

12. The method of claim 10 wherein the hydraulic cement comprises Portland cement.

13. The method of claim 10 wherein the latex composition comprises the natural pozzolan, and wherein the natural pozzolan comprises pumicite.

14. The method of claim 10 wherein the latex composition comprises the cement kiln dust in an amount of about 1% to about 99% by weight of cementitious components in the latex composition.

15. The method of claim 10 wherein the latex composition further comprises an additive selected from the group consisting of fly ash, slag cement, metakaolin, shale, zeolite, a gas, crystalline silica, amorphous silica, fumed silica, a salt, a fiber, a hydratable clay, a microsphere, rice husk ash, and any combination thereof.

16. The method of claim 10 wherein the latex composition further comprises an additive selected from the group consisting of a latex stabilizer, a strength-retrogression additive, a set accelerator, a set retarder, set accelerator, a weighting agent, a lightweight additive, a gas-generating additive, a mechanical property enhancing additive, a lost-circulation material, a filtration-control additive, a dispersant, a fluid loss control additive, a defoaming agent, a foaming agent, an oil-swellable particle, a water-swellable particle, a thixotropic additive, and any combination thereof.

17. The method of claim 10 wherein the latex composition is foamed.

18. The method of claim 10 wherein allowing the latex composition to set comprises allowing the latex composition to set in an annulus between the subterranean formation and a conduit disposed in the subterranean formation.

19. A latex composition comprising:

latex,

a component selected from the group a natural pozzolan, cement kiln dust, and a combination thereof, and

water.

20. The latex composition of claim 19 further comprising a hydraulic cement.
