%X Surfactants are known for their unique property in lowering the interfacial tension (IFT)  amid fluids injected and heavy crude oil of 22.3°API. In this present work, an original  surfactant was formulated from natural oil (Castor oil) to see its use in enhanced oil  recovery. The results from interfacial tension reduction by the castor oil-based  surfactant were compared to that of the industrial surfactant (Methyl ester sulfonate).  The IFT between the aqueous phases was measured then the effect of the surfactants  was studied in core flooding experiments. The IFT was found to be reduced to as low as  12.1 mN/m using the castor-based surfactant and 12.3 mN/m using the industrial  surfactant. The influence of brine concentration on IFT was also investigated. Results  from core floods showed that the range of oil recovery after waterflood is in the range of  30-40% and the additional recovery from surfactant flooding in the range of 35-46%.
