Patent ID: 8287640

Claim:
A method for preparing a foamed, gelled cement composition comprising: adding a cement to an aqueous fluid, adding a first additive composition comprising: a charged polymer, a stabilizing agent, and water adding a second additive composition comprising an oppositely charged surfactant, where the charged polymer and the oppositely charged surfactant form a pre-foamed, gelled slurry including an ionic gel system comprising the charged polymer ionically bonded to the oppositely charged surfactant, and injecting an amount of a gas sufficient to foam 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 350Â° 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.
