Abstract

Official abstract text for this publication.

Disclosed is a method of cementing. The method comprises providing a set-delayed cement composition comprising water, pumice, hydrated lime, a set retarder, and a micro-electrical-mechanical system; and allowing the set-delayed cement composition to set.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of cementing comprising: preparing a set-delayed cement composition comprising water, cementitious components, a set retarder, a polycarboxylated ether dispersant, and a micro-electrical-mechanical system, wherein the cementitious components comprise pumice and hydrated lime without any additional components that hydraulically set in the presence of water; and allowing the set-delayed cement composition to set. 2. The method of claim 1 , wherein the micro-electro-mechanical system is about 5 mm 2 or smaller. 3. The method of claim 1 , wherein the micro-electro-mechanical system is present in the set-delayed cement composition in an amount of about 0.01 weight percent to about 25 weight percent. 4. The method of claim 1 , further comprising using the micro-electro-mechanical system to sense one or more parameters. 5. 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. 6. The method of claim 1 wherein the set-delayed cement composition further comprises a cement set activator selected from the group consisting of a zeolite, amine, silicate, Group IA hydroxide, Group IIA hydroxide, monovalent salt, divalent salt, nanosilica, polyphosphate, and any combination thereof. 7. The method of claim 1 wherein the set-delayed cement composition further comprises a cement set activator comprising a combination of a monovalent salt and the polyphosphate. 8. The method of claim 1 wherein the set retarder comprises a phosphonic acid derivative. 9. The method of claim 1 further comprising introducing the set-delayed cement composition into a subterranean formation. 10. The method of claim 9 wherein the set-delayed 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. 11. The method of claim 1 further comprising, prior to the allowing step, storing the set-delayed cement composition for a time period of about 7 days or longer and then adding a cement set activator to the set-delayed cement composition. 12. A method of cementing comprising: preparing a set-delayed cement composition comprising water, a cementitious component comprising pumice and hydrated lime, a set retarder, a dispersant, a micro-electrical-mechanical system, an additional additive, wherein the additional additive is selected from the group consisting of a lightweight additive, a gas-generating additive, a mechanical property enhancing additive, a lost-circulation material, a defoaming agent, a foaming agent, a thixotropic additives, and any combination thereof, wherein the set-delayed cement composition is free of any additional cementitious components other than the pumice and the hydrated lime; adding a cement set activator to the set-delayed cement composition to activate by the set-delayed cement composition; and introducing the activated set-delayed cement composition into a subterranean formation. 13. The method of claim 12 , wherein the micro-electro-mechanical system is about 5 mm 2 or smaller. 14. The method of claim 13 , wherein the micro-electro-mechanical system is present in the set-delayed cement composition in an amount of about 0.01 weight percent to about 25 weight percent. 15. The method of claim 13 , further comprising using the micro-electro-mechanical system to sense one or more parameters. 16. The method 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. 17. The method of claim 13 , wherein the cement set activator comprises at least one cement set activator selected from the group consisting of a zeolite, amine, silicate, Group IA hydroxide, Group IIA hydroxide, monovalent salt, divalent salt, nanosilica, polyphosphate, and any combination thereof. 18. The method of claim 13 , wherein the a cement set activator comprises a combination of a monovalent salt and the polyphosphate. 19. The method of claim 13 , wherein the set retarder comprises a phosphonic acid derivative and the dispersant comprises a polycarboxylated ether dispersant. 20. The method of claim 13 , wherein the activated set-delayed 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, and wherein the method further comprises, prior to the allowing step, storing the set-delayed cement composition for a time period of about 7 days or longer and then the step of adding the cement set activator to the set-delayed cement composition. 21. The method of claim 1 , further comprising: storing the set-delayed cement composition in a pumpable fluid state for a time period of about 1 day or longer; reducing the density of the set-delayed cement composition; and introducing the set-delayed cement composition into a subterranean formation, wherein the storing the set-delayed cement composition occurs prior to the set-delayed cement composing being introduced into the subterranean formation, and wherein the reducing the density occurs after the storing the set-delayed cement composition and before the introducing the set-delayed cement composition into the subterranean formation.
