The present invention relates to cementing operations and, more
particularly, to foamed cement compositions, foaming and stabilizing
additives, and associated methods. A foaming and stabilizing additive,
that comprises a mixture of an alkali salt of an alkyl ether sulfate
surfactant, wherein the alkali salt of the alkyl ether sulfate surfactant
comprises a mixture of an alkali salt of a C.sub.6-10 alkyl ether sulfate
surfactant, and an alkali salt of a C.sub.2-4 alkyl ether sulfate
surfactant, an alkyl or alkene amidopropyl betaine surfactant, an alkyl
or alkene amidopropyl dimethylamine oxide surfactant, sodium chloride,
and water, is provided. Also provided are foamed cement compositions that
comprise the foaming and stabilizing additive, and associated methods.
