Patent ID: 8475585

Claim:
A foamed, gelled cement composition comprising: a foamable composition including: a cement, a water-based fluid present in an amount between about 20 wt. % and about 80 wt. % based on the weight of the cement, a foaming composition comprising (1) a first additive composition including (a) a charged polymer, (b) a stabilizing agent, and (c) a water and (2) a second additive composition comprising an oppositely charged surfactant present in an amount between about 0.05 wt. % and about 10 wt. % of the water-based fluid to form a pre-foamed, gelled slurry including an ionic gel system comprising the charged polymer ionically bonded to the oppositely charged surfactant, and a gas present in an amount between about 5 vol. % and about 85 vol. % based on the pre-foamed, gelled slurry to form the foamed, gelled cement composition, where the foamed, gelled cement composition is stable at temperatures from room temperature up to about 350° F. for a period of time sufficient for cement placement and cement setting and where the foamed, gelled cement composition is compressible prior to setting.
