Abstract

Disclosed herein are cement compositions and methods of using set-delayed cement compositions in subterranean formations. An embodiment includes a method of cementing in a subterranean formation comprising: providing a cement composition comprising water, pumice, hydrated lime, a set retarder, and a strength enhancer, wherein the strength enhancer comprises at least one material selected from the group consisting of cement kiln dust, slag, amorphous silica, a pozzolan, and any combination thereof; introducing the cement composition into the subterranean formation; and allowing the cement composition to set in the subterranean formation.

Claims

1. A method of cementing in a subterranean formation comprising:

providing a cement composition comprising water, pumice, hydrated lime, a set retarder, and a strength enhancer, wherein the strength enhancer comprises at least one material selected from the group consisting of cement kiln dust, slag, amorphous silica, a pozzolan, and any combination thereof;

introducing the cement composition into the subterranean formation; and

allowing the cement composition to set in the subterranean formation.

2. The method of claim 1 wherein the strength enhancer comprises the cement kiln dust and wherein the cement kiln dust is present in an amount of about 50% to about 100% by weight of the pumice.

3. The method of claim 1 wherein the strength enhancer comprises the slag and wherein the slag is present in an amount of about 50% to about 100% by weight of the pumice.

4. The method of claim 1 wherein the strength enhancer comprises the pozzolan and wherein the pozzolan is selected from the group consisting of diatomaceous earth, metakolin, fly ash, zeolite, and any combination thereof;

and wherein the pozzolan is present in an amount of about 0.1% to about 20% by weight of the pumice.

5. The method of claim 1 wherein the strength enhancer comprises the pozzolan, wherein the method further comprises preparing the cement composition, the preparing comprises combining an additive comprising a cement set activator and the pozzolan with a set-delayed cement composition.

6. The method of claim 1 wherein the strength enhancer comprises the amorphous silica and wherein the amorphous silica is present in an amount of about 0.1% to about 20% by weight of the pumice.

7. The method of claim 1 wherein the set retarder comprises at least one retarder selected from the group consisting of a phosphate, a phosphonate, a phosphonic acid, a phosphonic acid derivative, a lignosulfonate, a salt, an organic acid, a carboxymethylated hydroxyethylated cellulose, a synthetic co- or ter-polymer comprising sulfonate and carboxylic acid groups, a borate compound, and any mixture thereof.

8. The method of claim 1 wherein the cement composition further comprises a cement set activator selected from the group consisting of zeolites, amines, silicates, Groups IA and IIA hydroxides, monovalent salts, divalent salts, nanosilica, polyphosphates, and any combination thereof.

9. The method of claim 1 wherein the cement composition further comprises a cement set activator comprising a combination of a monovalent salt and the polyphosphate.

10. The method of claim 1 wherein the cement composition further comprises a one dispersant selected from the group consisting of a sulfonated-formaldehyde-based dispersant, a polycarboxylated ether dispersant, and any combination thereof.

11. The method of claim 1 wherein the cement composition is introduced into an annulus between a conduit disposed in a well bore and a wall of the well bore or another conduit.

12. The method of claim 1 further comprising, prior to the introducing step, storing the cement composition for a time period of about 7 days and then adding a cement set activator to the cement composition.

13. A cement composition comprising:

water;

pumice;

hydrated lime;

a set retarder; and

a strength enhancer, wherein the strength enhancer is selected from the group consisting of cement kiln dust, slag, amorphous silica, and a pozzolan.

14. The composition of claim 13 wherein the strength enhance comprises the cement kiln dust and wherein the cement kiln dust is present in an amount of about 50% to about 100% by weight of the pumice.

15. The composition of claim 13 wherein the strength enhancer comprises the slag and wherein the slag is present in an amount of about 50% to about 100% by weight of the pumice.

16. The composition of claim 13 wherein the strength enhancer comprises the pozzolan and wherein the pozzolan is selected from the group consisting of diatomaceous earth, metakaolin, fly ash, zeolite, or any combination thereof;

and wherein the pozzolan is present in an amount of about 0.1% to about 20% by weight of the pumice.

17. The composition of claim 13 wherein the strength enhancer comprises amorphous silica and wherein the amorphous silica is present in an amount of about 0.1% to about 20% by weight of the pumice.

18. The composition of claim 13 wherein the set retarder comprises at least one retarder selected from the group consisting of a phosphate, a phosphonate, a phosphonic acid, a phosphonic acid derivative, a lignosulfonate, a salt, an organic acid, a carboxymethylated hydroxyethylated cellulose, a synthetic co- or ter-polymer comprising sulfonate and carboxylic acid groups, a borate compound, and any mixture thereof.

19. The composition of claim 13 further comprising an additive comprising a cement set activator and the pozzolan.

20. The composition of claim 13 further comprising a cement set activator comprising at least one set activator selected from the group consisting of zeolites, amines, silicates, Groups IA and IIA hydroxides, monovalent salts, divalent salts, nanosilica, polyphosphates, and any combination thereof.

21. The composition of claim 13 wherein the cement composition is capable of remaining in a pumpable fluid state for a period of about 1 day or longer.

22. A cementing system comprising:

a cement composition comprising;

water,

pumice,

hydrated lime,

a set retarder, and

a strength enhancer, wherein the strength enhancer is selected from the group consisting of cement kiln dust, slag, amorphous silica, and a pozzolan; and
