Abstract: Intelligent water flooding is method to increase oil recovery during previous years. Amount of injected water salt is key factor to intelligent water flooding process. The tension between salty water and oil is important factor to enhance recovery. In fact intra surface tension is effective on capillary number. Decreasing tension between surfaces, capillary number would be increased. The aim of this study is evaluation of water salt effect on surface tension. The interfacial tension between salty water and oil is calculated using salt density, pressure and temperature. The tension is measured using suspended drop method that is dynamic test. Also the effect of time passing on intra facial tension is evaluated. Findings show the lowest tension is defined between 10000-20000 ppm based on salt density. The effect of temperature is more than pressure. Therefore, in high temperature, the tension would be decreased.
