Critical review on the use of natural surfactants in enhanced oil recover

Abstract

The enormous energy demand, wide requirement for progressively crude oil production and the low-productivity of the regular strategies are the reasons of expanding interests to Enhanced Oil Recovery (EOR) techniques for recuperating more oil from the current reservoirs. Elective energy sources have not yet introduced reasonable to satisfy the energy need of the world; in this way crude oil will play a basic job in the energy utilization later on. Considering the way that the effectively recoverable oil is running out and much oil stays in the reservoir after conventional strategies have been depleted, the execution of Enhanced Oil Recovery has gotten essential to ensure a continuing crude oil supply. EOR is a challenging field for several petroleum engineers. One of the most widely recognized strategies for enhanced oil recovery is the use of various sorts of surfactants (manufactured or natural) so as to diminish the oil-water interfacial tension. Be that as it may, the surfactants being utilized today are normally synthetic chemicals and polymers, which are costly, connected to fossil fuels, and unfavorable to the environment. In this review common surfactants are examined. Surfactants were removed from the leaves of the tended to plants and the impact of these surfactants on the interfacial tension between water or brackish water and oil is researched. Using these surfactants reduced the interfacial tension between oil and water and that explained in the discussion by different authors using different natural surfactants from different plants over different years of investigation and reviewing. Provided comparisons of interfacial tension versus different surfactants concentrations. Results of these examinations could help analysts in the future to learn about application of natural surfactants in the Enhanced Oil Recovery focuses in petroleum reservoirs. Plant surfactant flooding is suitable choice for EOR owing to significant reduction in interfacial tension and the amount of residual oil in reservoir.
