“…Studies performed by Curbelo et al (2007;2008) show that solutions of surfactants R200, SB, and OCS injected, individually, had recovery factors (Figure 3.a). However, for synergism to R200/SB mixture, recovery factor increased to 70.0% (Figure 3b).…”

Adsorption of surfactants from aqueous solutions in porous media is fundamental in enhanced oil recovery (EOR) because surfactant loss reduces the effectiveness of the chemical solution injected, making the process economically unfeasible. This paper analyzes surfactants' synergistic effects in adsorption and enhanced oil recovery. This study used nonionic (nonylphenol 20 ethylene oxide -R200) and anionic surfactants (saponified coconut oil -OCS and base soap -SB) with the two mixtures studied (R200/OCS and R200/SB). The mixture R200/SB, due to its higher viscosity because of the presence of SB, saturated the ionic surfactant (SB) faster, reaching a higher oil recovery (70.0%). The addition of SB surfactant in the R200 solution led to an increase in oil recovery (70.0%) when compared to R200 alone (64.5%).

Three different types of surfactants containing an anionic, a cationic and a new nonionic biosurfactant, Zizyphus Spina-Christi extract were used for the purpose of oil recovery in a core flood system. Core flooding tests were conducted on sandstone to test the effectiveness of surfactants in tertiary oil recovery. Extensive research including adsorption behavior of surfactants on the rock surface and interfacial tension (IFT) measurements were used to analyze the surfactant flooding performance. An additional recovery varying between 6.15 % and 12.17 % of original oil in place (OOIP) was obtained by surfactant solution injection. The results indicated that the new biosurfactant can be used as an enhanced oil recovery (EOR) agent either for IFT reduction or wettability alteration purpose. Furthermore, availability and the low cost of the Zizyphus Spina-Christi extract in comparison to common chemical surfactants in petroleum industry make it economically viable for surfactant flooding.
