Abstract

These days, Enhanced Oil Recovery (EOR) technology is commonly applied in mature fields. Chemical flooding is one of the many kinds of EOR technology. It uses chemical substances such as Surfactant, Alkali, Polymer and Low-Salinity water for improving oil recovery. Surfactant can reduce oil/water IFT (lnterfacial of tension) to increase oil recovery. IFT can be measured through phase behavior experiments. Phase behavior of surfactant solutions has been studied in the literature such as Levitt et al. (2006), Zhao et al. (2008). By conducting phase behavior experiments, an effective surfactan for specific oil was determinated. Generally, solubilization ratio will become over IO for reducing IFT in that case oil's mobility will increases. In the experiments, it was used the mixtures of single-tail anionic surfactant (LAS : Linear Alkylbenze Sulphonate) and double-tail anionic surfactant (DOSS : Dioctyl Sodium Sulfosuccinate) from AK company. And it was used Medium-heavy which bas 25° A.PI and l 2cp viscosity in the 25 °C. In the results, the mixture of Surfactants, in which double-tail anionic surfactant concentration is higher than single-tail anionic surfactant concentration, shows high solubilization ratio. But 4-5 solubilization ratio was measured in the experiments. It was estimated that surfactant from household detergents was used in the research. So synthesized EOR surfactant will be used to achieve better result for next study.
