Abstract

Embodiments relate to cementing operations and, more particularly, in certain embodiments, to settable compositions that comprise kiln dust and wollastonite and methods of use in subterranean formations. An embodiment discloses a method of cementing comprising: providing a settable composition comprising kiln dust, wollastonite, and water; and allowing the settable composition to set.

Claims

1. A method of cementing comprising:

providing a settable composition comprising kiln dust, wollastonite, and water;

wherein the wollastonite is present in the settable composition in an amount in a range of from about 1% to about 75% by weight of a total amount of cementitious components present in the settable composition, wherein the kiln dust is present in the settable composition in an amount in a range of from about 5% to about 90% by weight of a total amount of cementitious components present in the settable composition; and

allowing the settable composition to set, wherein the settable composition is introduced into a subterranean formation.

2. The method of claim 1 wherein the kiln dust comprises at least one partially calcined kiln feed selected from the group consisting of cement kiln dust, lime kiln dust, and a combination thereof.

3. The method of claim 1 wherein the kiln dust comprises SiO₂, Al₂O₃, Fe₂O₃, CaO, MgO, SO₃, Na₂O, and K₂O.

4. The method of claim 1 wherein the kiln dust is present in the settable composition in an amount in a range of from about 5% to about 50% by weight of a total amount of cementitious components present in the settable composition.

5. The method of claim 1 wherein the settable composition further comprises Portland cement.

6. The method of claim 5 wherein the Portland cement is present in the settable composition in an amount in a range of from about 1% to about 75% by weight of a total amount of cementitious components present in the settable composition.

7. The method of claim 6 wherein the Portland cement is present in the settable composition in an amount in a range of from about 10% to about 50% by weight of a total amount of cementitious components present in the settable composition, wherein the kiln dust is present in the settable composition in an amount in a range of from about 10% to about 50% by weight of the total amount of cementitious components present in the settable composition, and wherein the wollastonite is present in the settable composition in an amount in a range of from about 10% to about 50% by weight of the total amount of cementitious components present in the settable composition.

8. The method of claim 1 wherein the water is present in an amount sufficient to form a pumpable slurry.

9. The method of claim 1 wherein the settable composition further comprises at least one additive selected from the group consisting of fly ash, slag, shale, zeolite, metakaolin, pumice, perlite, lime, silica, rice husk ash, small-particle size cement, and any combination thereof.

10. The method of claim 1 wherein the settable composition further comprises at least one additive selected from the group consisting of a dispersant, a strength-retrogression additive, a set accelerator, a set retarder, a weighting agent, a lightweight additive, a gas-generating additive, a Mechanical property enhancing additive, a lost-circulation material, a fluid loss control additive, a foaming additive, a defoaming additive, an oil-swellable particle, a water-swellable particle, a thixotropic additive, crystalline silica, fumed silica, silicates, salts, fibers, hydratable clays, microspheres, diatomaceous earth, elastomers, elastomeric particles, resins, latex and any combination thereof.

11. The method of claim 1 wherein the settable composition is foamed with a foaming agent and a gas.

12. The method of claim 1 wherein the settable composition is used in primary cementing.

13. The method of claim 1 wherein the settable composition is used in remedial cementing.

14. The method of claim 1 wherein the wollastonite is present in the settable composition in an amount of about 10% to about 75% by weight of a total amount of cementitious components present in the settable composition.

15. A method of cementing comprising:

introducing a settable composition into a well bore annulus, wherein the settable composition comprises cement kiln dust, wollastonite, Portland cement, water, and an additive selected from the group consisting of fly ash, slag, shale, zeolite, metakaolin, pumice, perlite, lime, silica, rice husk ash, small-particle size cement, and any combination thereof;

wherein the wollastonite is present in the settable composition in an amount in a range of from about 1% to about 75% b weight of a total amount of cementitious components present in the settable composition, wherein the kiln dust is present in the settable composition in an amount in a range of from about 5% to about 90% by weight of a total amount of cementitious components present in the settable composition; and

allowing the settable composition to set.

16. The method of claim 15 wherein the Portland cement is present in the settable composition in an amount in a range of from about 10% to about 50% by weight of a total amount of cementitious components present in the settable composition, wherein the cement kiln dust is present in the settable composition in an amount in a range of from about 10% to about 50% by weight of the total amount of cementitious components present in the settable composition, and wherein the wollastonite is present in the settable composition in an amount in a range of from about 10% to about 50% by weight of the total amount of cementitious components present in the settable composition.

17. The method of claim 16 wherein the settable composition comprises the metakaolin in an amount in a range of from about 10% to about 50% by weight of the total amount of cementitious components present in the settable composition.

18. The method of claim 15 wherein the woliastonite is present in the settable composition in an amount of about 10% to about 75% by weight of a total amount of cementitious components present in the settable composition.
