The present invention relates to foamed cement slurries, additives and methods. A foamed cement slurry of the invention comprises a hydraulic cement, sufficient water to form a slurry, sufficient gas to form a foam and an environmentally benign foaming and stabilizing additive comprising a mixture of an ammonium salt of an alkyl ether sulfate surfactant, a cocoamidopropyl hydroxysultaine surfactant, a cocoamidopropyl dimethylamine oxide surfactant, sodium chloride and water.

1. A method of cementing comprising the steps of:preparing a foamed cement slurry comprising a hydraulic cement, sufficient water to form a slurry, sufficient gas to form a foam, and a foaming and stabilizing additive comprising a mixture of an ammonium salt of an alkyl ether sulfate surfactant, a cocoamidopropyl hydroxysultaine surfactant, a cocoamidopropyl dimethylamine oxide surfactant, sodium chloride and water;placing the foamed cement slurry in a location to be cemented; andallowing the cement slurry to set.2. The method of claim 1 wherein the hydraulic cement comprises Portland cements, slag cements, silica cements, pozzolana cements or aluminous cements.3. The method of claim 1 wherein the water comprises fresh water, unsaturated salt solutions and saturated salt solutions.4. The method of claim 1 wherein the water in the foamed cement slurry is present in an amount in the range of from about 35% to about 70% by weight of hydraulic cement therein.5. The method of claim 1 wherein the gas comprises air or nitrogen.6. The method of claim 1 wherein the gas in the foamed cement slurry is present in the range of from about 10% to about 80% by volume of the water in the cement slurry.7. The method of claim 1 wherein the ammonium salt of an alkyl ether sulfate surfactant in the foaming and stabilizing additive is a mixture of 30.15% by weight of an ammonium salt of a C6-10 alkyl ether sulfate surfactant containing 1.8 moles of ethylene oxide, 10.05% by weight of an ammonium salt of a C4 alkyl ether sulfate surfactant containing 2 moles of ethylene oxide, and 0.40% by weight of ammonium sulfate.8. The method of claim 1 wherein the cocoamidopropyl hydroxysultaine surfactant in the foaming and stabilizing additive is present in an amount of about 8.54% by weight of the additive.9. The method of claim 1 wherein the cocoamidopropyl dimethylamine oxide surfactant in the foaming and stabilizing additive is present in an amount of about 1.43% by weight of the additive.10. The method of claim 1 wherein the sodium chloride in the foaming and stabilizing additive is present in an amount of about 6.02% by weight of the additive.11. The method of claim 1 wherein the water in the foaming and stabilizing additive is present in an amount of about 43.41% by weight of the additive.12. The method of claim 1 wherein the foaming and stabilizing additive in the foamed cement slurry is present in an amount in the range of from about 0.8% to about 10% by volume of the water in the foamed cement slurry.13. The method of claim 1 wherein the location to be cemented is above ground, below ground or in a well.14. A method of cementing a subterranean zone penetrated by a well bore comprising the steps of:preparing a foamed cement slurry comprising a hydraulic cement, sufficient water to form a slurry, sufficient gas to form a foam, and a foaming and stabilizing additive comprising a mixture of an ammonium salt of an alkyl ether sulfate surfactant, cocoamidopropyl hydroxysultaine surfactant, cocoamidopropyl dimethylamine oxide surfactant, sodium chloride and water;placing the foamed cement slurry in the subterranean zone by way of the well bore; andallowing the foamed cement slurry to set into a hard impermeable mass.15. The method of claim 14 wherein the hydraulic cement comprises Portland cements, slag cements, silica cements, pozzolana cements or aluminous cements.16. The method of claim 14 wherein the water comprises fresh water, unsaturated salt solutions and saturated salt solutions.17. The method of claim 14 wherein the water in the foamed cement slurry is present in an amount in the range of from about 35% to about 70% by weight of hydraulic cement therein.18. The method of claim 14 wherein the gas comprises air or nitrogen.19. The method of claim 14 wherein the gas in the foamed cement slurry is present in the range of from about 10% to about 80% by volume of the water in the cement slurry.20. The method of claim 14 wherein the ammonium salt of an alkyl ether sulfate surfactant in the foaming and stabilizing additive is a mixture of 30.15% by weight of an ammonium salt of a C6-10 alkyl ether sulfate surfactant containing 1.8 moles of ethylene oxide, 10.05% by weight of an ammonium salt of a C4 alkyl ether sulfate surfactant containing 2 moles of ethylene oxide, and 0.40% by weight of ammonium sulfate.21. The method of claim 14 wherein the cocoamidopropyl hydroxysultaine surfactant in the foaming and stabilizing additive is present in an amount of about 8.54% by weight of the additive.22. The method of claim 14 wherein the cocoamidopropyl dimethylamine oxide surfactant in the foaming and stabilizing additive is present in an amount of about 1.43% by weight of the additive.23. The method of claim 14 wherein the sodium chloride in the foaming and stabilizing additive is present in an amount of about 6.02% by weight of the additive.24. The method of claim 14 wherein the water in the foaming and stabilizing additive is present in an amount of about 43.41% by weight of the additive.25. The method of claim 14 wherein the foaming and stabilizing additive in the foamed cement slurry is present in an amount in the range of from about 0.8% to about 10% by volume of the water in the foamed cement slurry.
