Abstract

Methods and compositions for cementing operations that include pumice in geopolymer cement compositions comprising slag.

Claims

1. A method of cementing comprising:

providing a geopolymer cement composition consisting of;

a cementitious component consisting essentially of slag and pumice;

hydrated lime;

an additive selected from the group consisting of crystalline silica, amorphous silica, fumed silica, a fiber, a hydratable clay, calcined shale, vitrified shale, a microsphere, diatomaceous earth, metakaolin, ground perlite, rice husk ash, zeolite, a resin, a dispersant, a defoaming agent, a set retarder, a weighting agent, a lightweight additive, a gas-generating additive, a lost-circulation material, a filtration-control additive, a fluid-loss-control additive, a foaming additive, a thixotropic additive, and any combination thereof; and

water; and

allowing the geopolymer cement composition to set;

wherein the geopolymer cement composition does not comprise a set accelerator.

2. The method of claim 1, wherein the geopolymer cement composition has a density of about 12 pounds per gallon to about 20 pounds per gallon.

3. The method of claim 1, wherein the slag is present in an amount in a range of from about 40% to about 100% by weight of the cementitious component.

4. The method of claim 1, wherein the pumice is present in an amount in a range of from about 0.1% to about 60% by weight of the cementitious component.

5. The method of claim 1, wherein the slag is present in an amount in a range of from about 40% to about 60% by weight of the cementitious component, and wherein the pumice is present in an amount in a range of from about 40% to about 60% by weight of the cementitious component.

6. The method of claim 1, wherein the cementitious component consists of the slag and the pumice.

7. The method of claim 6, wherein the geopolymer cement composition is free of any additional cementitious materials.

8. The method of claim 1, wherein the hydrated lime is present in an amount in a range of from about 0.1% to about 25% by weight of the cementitious component.

9. The method of claim 1, further comprising introducing the geopolymer cement composition into a subterranean formation.

10. The method of claim 9, wherein introducing the geopolymer cement composition into a subterranean formation comprises introducing the geopolymer cement composition into a well-bore annulus.

11. The method of claim 1, wherein the geopolymer cement composition is used in a primary cementing operation.

12. The method of claim 1, wherein inclusion of the pumice in the geopolymer cement composition increases the 24-hour compressive strength of the geopolymer cement composition at 180°

F. in an amount of at least about 5% as compared to replacement of the pumice with additional slag.

13. A method of cementing comprising:

preparing a geopolymer cement composition consisting of water, hydrated lime, an additive, and a cementitious component comprising slag and pumice, wherein the additive is selected from the group consisting of crystalline silica, amorphous silica, fumed silica, a fiber, a hydratable clay, calcined shale, vitrified shale, a microsphere, diatomaceous earth, metakaolin, ground perlite, rice husk ash, zeolite, a resin, a dispersant, a defoaming agent, a set retarder, a weighting agent, a lightweight additive, a gas-generating additive, a lost-circulation material, a filtration-control additive, a fluid-loss-control additive, a foaming additive, a thixotropic additive, and any combination thereof;

introducing the geopolymer cement composition into a subterranean formation; and

allowing the geopolymer cement composition to set;

wherein the geopolymer cement composition does not comprise a set accelerator.

14. The method of claim 13, wherein the slag is present in an amount in a range of from about 40% to about 60% by weight of the cementitious component, and wherein the pumice is present in an amount in a range of from about 40% to about 60% by weight of the cementitious component.

15. The method of claim 13, wherein the cementitious component consists of the slag and the pumice.

16. The method of claim 15, wherein the geopolymer cement composition is free of any additional cementitious materials.

17. The method of claim 13, wherein the hydrated lime is present in an amount in a range of from about 0.1% to about 25% by weight of the cementitious component.

18. The method of claim 13, wherein introducing the geopolymer cement composition into a subterranean formation comprises introducing the geopolymer cement composition into a well-bore annulus.

19. The method of claim 13, wherein inclusion of the pumice in the geopolymer cement composition increases the 24-hour compressive strength of the geopolymer cement composition at 180°

F. in an amount of at least about 5% as compared to replacement of the pumice with additional slag.

20. A method of cementing comprising:

providing a geopolymer cement composition consisting of;

a cementitious component consisting of slag in an amount in a range of from about 40% to about 60% by weight of the cementitious component and pumice in an amount in a range of from about 40% to about 60% by weight of the cementitious component, wherein the geopolymer cement composition is free of any additional cementitious component;

hydrated lime in an amount in a range of from about 0.1% to about 20% by weight of the cementitious component;

an additive selected from the group consisting of crystalline silica, amorphous silica, fumed silica, a fiber, a hydratable clay, calcined shale, vitrified shale, a microsphere, diatomaceous earth, metakaolin, ground perlite, rice husk ash, zeolite, a resin, a dispersant, a defoaming agent, a set retarder, a weighting agent, a lightweight additive, a gas-generating additive, a lost-circulation material, a filtration-control additive, a fluid-loss-control additive, a foaming additive, a thixotropic additive, and any combination thereof; and
