One of enhanced oil recovery techniques to produce more oil production is surfactant flooding. The surfactants are considered as the effective chemicals used in oilfield in Thailand. It is used to lower the interfacial tension (IFT) of two fluids and to increase mobility in the reservoir. For this study, various chemicals such as amine, fatty alcohol and glycerine are applied as the surfactants to reduce IFT between oil and water. Therefore, the aim of this work is to investigate the potential chemicals and measure the IFT reduction based on the conditions of subsurface at the oilfield in Thailand. These parameters such as temperature, pressure as well as the concentration of surfactant are adjusted to investigate the effects on IFT reduction. From the results, it is reported that pressure from 1, 000 to 2, 000 psi and temperature varied from 70 °C to 90 °C can reduce IFT insignificantly. However, types of chemicals and surfactant concentration are the main parameters that impact on the IFT reduction. Monoethanolamine at 4.0 wt. % can greatly decrease IFT up to 87 % for surfactant concentration. Finally, the results can be applied to use in the real field for enhanced oil production in Thailand.
