The effect of an in house developed CO2 philic surfactant in foam assisted WAG (FAWAG) on CO2 mobility is reported. We reacted methallyl chloride with nonylphenol ethoxylated alcohol and then sulfonated the produced product. The effect of surfactant on IFT between CO2 and brine was investigated in order to measure the affinity of surfactant with CO2. The detailed effects of pressure and temperature on IFT between CO2 / brine / surfactant at the specified pressure and temperature conditions is studied and reported. In-house developed surfactant effectively lowered down the IFT between CO2/brine from 32 mN/m to less than 6.10 mN / m. In addition, the newly developed surfactant was evaluated for its foam stability. The synthesized novel surfactant was further investigated for its effect on CO2 mobility in porous media and the findings are presented here. The in house developed surfactant has a great potential for CO2− EOR applications.
