Chemical EOR should be optimized by oil companies so that it would be much more widely applicable under different circumstances and conditions. However, the current employed chemical EOR has its limitations such as that the chemicals used in chemical EOR are usually costly and have certain application constraints. In this research, the effect of temperature, salinity, and concentration on the performance of Arginine as a surfactant for IFT reduction in chemical EOR has been investigated. IFT-700 has been used to find the interfacial tension (IFT) at, 40°C and 60°C, using three brine salinities: 10,000 ppm, 30,000 ppm, 50,000 ppm at varying surfactant’s concentrations. At each temperature, the experiment is repeated using different brine salinities and surfactant’s concentrations. Based upon the outcome of this study, it can be proposed that Arginine works best as an IFT reduction chemical at elevated temperature and low salinity environment.
