Abstract

An example method of cementing in a subterranean formation includes determining a settable composition for use in the subterranean formation; calculating a total carbon footprint of the settable composition; determining at least one additive for use in the settable composition, wherein the additive replaces at least a portion of the settable composition and reduces the total carbon footprint of the settable composition; preparing the settable composition comprising the additive; placing the settable composition comprising the additive in the subterranean formation; and allowing the settable composition comprising the additive to set in the subterranean formation. Additional embodiments of the present invention include determining an amount of reduction in the carbon footprint of the settable composition; and/or communicating the amount of reduction in the carbon footprint of the settable composition to a customer or end user.

Claims

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

calculating a total carbon footprint of a settable composition comprising hydraulic cement, wherein the calculating the total carbon footprint is based on carbon dioxide produced in production of the hydraulic cement;

reducing the total carbon footprint of the settable composition by replacing at least a portion of the settable composition with an additive, wherein the additive comprises cement kiln dust;

placing the settable composition in the subterranean formation, wherein the placing the settable composition in the subterranean formation comprises placing the settable composition in an annulus between the subterranean formation and a pipe string; and

allowing the settable composition to set in the subterranean formation.

2. The method of claim 1 wherein the hydraulic cement comprises Portland cement in the settable composition.

3. The method of claim 1 wherein the additive is present in the settable composition in an amount sufficient to achieve at least about a 1% reduction in the total carbon footprint of the settable composition.

4. The method of claim 1 wherein the additive is present in the settable composition in an amount sufficient to achieve at least about a 25% reduction in the total carbon footprint of the settable composition.

5. The method of claim 1 wherein the settable composition comprises the hydraulic cement and water.

6. The method of claim 1 further comprising determining an amount of reduction in the carbon footprint of the settable composition based on carbon dioxide produced in production of the replaced portion of the settable composition.

7. The method of claim 6 further comprising communicating the amount of reduction in the carbon footprint of the settable composition to a customer or end user.

13. The method of claim 1 wherein the calculating the total carbon footprint comprises determining the amount of carbon dioxide produced when creating one pound of the hydraulic cement.

14. The method of claim 1 wherein the calculating the total carbon footprint comprises determining carbon input into production of the hydraulic cement.

15. The method of claim 6 wherein the determining the amount of reduction in the total carbon footprint comprises determining a difference in embodied carbon between the replaced portion of the settable composition and the additive.

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

providing a settable composition comprising hydraulic cement;

including an additive in the settable composition, wherein the additive comprises cement kiln dust;

calculating a carbon footprint reduction for the settable composition based on carbon dioxide produced in production of the hydraulic cement and the additive;

placing the settable composition in the subterranean formation, wherein the placing the settable composition in the subterranean formation comprises placing the settable composition in an annulus between the subterranean formation and a pipe string; and

allowing the settable composition to set in the subterranean formation.

9. The method of claim 8 wherein the hydraulic cement comprises Portland cement and the additive replaces at least a portion of the Portland cement in the settable composition.

10. The method of claim 8 wherein the additive is present in the settable composition in an amount sufficient to achieve at least about a 1% carbon footprint reduction.

11. The method of claim 8 wherein the additive is present in the settable composition in an amount sufficient to achieve at least about a 25% carbon footprint reduction.

12. The method of claim 8 further comprising communicating the carbon footprint reduction to a customer or end user.

16. The method of claim 8 wherein the calculating the carbon footprint reduction comprises determining an amount of hydraulic cement replaced by including the additive in the settable composition.

17. The method of claim 16 wherein the calculating the carbon footprint reduction comprises determining a difference in embodied carbon between the amount of hydraulic cement replaced and the additive.
