Phase diagrams for pseudo three-component system, brine (0.5wt% NaCl) /2, 2, 4-trimethylpentane/Aerosol OT (sodium 1, 2-bis (2-ethylhexyloxycarbonyl) -1-ethanesulfonate) was studied in a wide range of temperature (2090°C). An excess wate is separated from solubilization curve below 41°C, whereas an excess oil is separated above 45°C. Hence, the solution behavior of Aerosol OT in brine-oil is similar to that of nonionic surfactant in water-oil, but the effect of temperature is in reverse. The amount of solubilized oil or water is not proportional to the concentration of Aerosol OT
