**10. CO2-philic surfactants as potential CO2 gas mobility control agent**

Although carbon dioxide has many advantages as being not-toxic, inexpensive, and gas that is not flammable overall process wipe-out efficiency is limited by the minimum viscosity, low density and the increase movement of the carbon dioxide. Most significantly, the poor process sweep efficiency that is caused due to the low density resulting in high velocity of carbon dioxide gas results in sticky fingering, an soon breakthrough of the inserted carbon dioxide gas and override of gravity. This undesired ratio of movement brings the process to a week wipe-out efficiency and subsequently oil recovery is less anticipated.

To reach the high recovery of oil, concerns regarding carbon dioxide movement have to be solved. By the use of foam the carbon dioxide movement can be efficiently controlled [7–10]. The velocity of carbon dioxide can be reduced

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
