Surfactant Interfacial Tension in Varying Salinity and Temperature Condition

Chemical flooding has been studied as an efficient Enhanced Oil Recovery (EOR) method for years and the used of surfactant in the process is one of the promising Chemical EOR methods. Recently, newly designed surfactants known as CL 10 and IL 10 have been proposed in EOR but unfortunately their performance and behaviors are still unknown.
Therefore, this project will investigate their behavior with the crude oil and their ability in reducing Interfacial Tension (IFT) to ensure an efficient CEOR. Even though there are several parameters that can affect the surfactants behavior, temperature and salinity are the most sensitive
parameters which effects will be determined in this project. Since IFT is very significant to show the behavior and performance of surfactants, the pendant drop tensiometer is used to determine the IFT between the surfactant and the crude oil thus getting the results for the project. For the
effect of salinity, both CL10 and IL10 have tolerant to the high salinity while for the effect of temperature, only CL10 show better tolerant to high range of temperature. In conclusion, CL10 is better surfactant that IL10 in
reducing IFT to the lowest.
