This study uses a natural surfactant extracted from Cordia myxa leaf for surfactant flooding, and experimentally demonstrates that it can effectively reduce interfacial tension and improve wettability. Core flooding results show that the use of this surfactant can increase oil recovery and reduce residual oil saturation in porous media.
It is necessary to enhance oil production from reservoir due to increase of the fossil fuel consumption that results of industrial life development. Surfactant flooding is a popular method to enhance oil recovery by IFT reduction and wettability alteration. In this study, a new natural surfactant that extracted from Cordia myxa leaf is used for surfactant flooding. The effect of this natural surfactant on IFT and wettability is investigated experimentally. Then, surfactant flooding is applied in a carbonate core sample. The results show the IFT of solution was reduced from 33/28mN/M at 0?wt% to 16.24 mN/M at 6?wt% by increasing natural surfactant concentration. More than, contact angle was decreased from 137.05? at 0?wt. % to 130.65? at 5.5?wt. %. The core flooding results show C. myxa flooding increased 27% more oil recovery compared to water flooding and reduced residual oil saturation in porous media. The results show C. myxa can be applicable as a green surfactant for enhancing oil recovery.
