by foam and it brings down the breakthrough of the inserted gas along with the reduction in the production of gas cap gas. With many advantages of foam it also has a few disadvantages, as instability beneath reservoir situation, For example, maximum salinity, maximum temperature, and particularly in the existence of oil. Incorporation of CO2-philic surfactants promotes the foam stability. Surfactants are very distinctive molecules having a H2O soluble part (head) as well as an oil soluble part (tail). From the generation of foam to IFT reduction, the surfactants tends to play vital roles in increasing oil recovery. For stable foam generation in carbon dioxide mobility control applications the CO2-philic surfactants are employed. Like the other surfactants, these surfactants also have two different parts, tail and head; therefore, the tail for these surfactants has an empathy for carbon dioxide gas to balance the spume [41–45].
