Abstract

The present invention relates to stable and biodegradable 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 a biodegradable foaming and stabilizing additive comprising a mixture of a capryl/capramido propyl betaine surfactant and a capryl/capramido propyl dimethyl amine oxide surfactant.

Claims (34)

1. 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 a capryl/capramido propyl betaine surfactant and a capryl/capramido propyl dimethyl amine oxide surfactant.
2. The foamed cement slurry of claim 1 wherein the hydraulic cement comprises Portland cement, slag cement, silica cement, pozzolana cement or aluminous cement.
3. The foamed cement slurry of claim 1 wherein the water comprises fresh water, unsaturated salt solutions or saturated salt solutions.
4. The foamed cement slurry of claim 1 wherein the water is present in an amount in the range of from about 35% to about 100% by weight of hydraulic cement therein.
5. The foamed cement slurry of claim 1 wherein the gas comprises air or nitrogen.
6. The foamed cement slurry of claim 1 wherein the gas is present in an amount in the range of from about 10% to about 80% by volume of the cement slurry.
7. The foamed cement slurry of claim 1 wherein the foaming and stabilizing additive is a mixture of 95% by weight capryl/capramido propyl betaine surfactant and 5% by weight capryl/capramido propyl dimethyl amine oxide surfactant.
