    摘要: Embodiments of the present disclosure include compositions for use in enhanced oil recovery, and methods of using the compositions for recovering oil. Compositions of the present disclosure include a nonionic, non-emulsifying surfactant having a CO2-philicity in a range of about 1.5 to about 5.0, carbon dioxide in a liquid phase or supercritical phase, and water, where the nonionic, non-emulsifying surfactant promotes a formation of a stable foam formed of carbon dioxide and water.
