A surfactant composition including a CAOS and/or CAOS, and an effective amount of at least one solubilizing component so as to increase brine tolerance of the composition is disclosed. The solubilizing component comprises a mixture of where X is H, an alkali metal, alkaline earth metal or ammonium, and R is a linear C-Calkyl group. A method of recovering hydrocarbons from a reservoir during gas injection into said reservoir is also disclosed which involves at least periodically injecting the gas and a foam-forming surfactant composition into the reservoir so as to assist in the recovery of hydrocarbons from the reservoir.

Surfactant formulations for aqueous foam stability at high temperature and high salinity conditions

A surfactant composition including a CAOS and/or CAOS, and an effective amount of at least one solubilizing component so as to increase brine tolerance of the composition is disclosed. The solubilizing component comprises a mixture of

Embodiments of the present disclosure are directed towards methods of enhanced oil recovery from a subterranean reservoir, the method includes co-injecting a gas and a foam formulation into the subterranean reservoir, wherein the gas comprises steam and the foam formulation comprises a sulfonate composition, a glycol compound, and water.

Enhanced oil recovery methods and compositions

The present invention includes a foam-forming composition for use in enhanced heavy oil recovery, and a method of using said foam-forming composition for recovering heavy oil and/or bitumen. The foam-forming composition of the present invention comprises a mixture of (di)alkyl diphenyloxide (di)sulfonate compounds and the process of heavy oil recovery is performed at elevated temperatures using steam.
