Abstract: Foam Flooding is an effective process in enhanced oil re-covery for the favorable mobility control ability. In the past sev-eral decades many efforts were made to find models, including theoretical, empirical and semi-empirical prediction models,for predicting reservoir performance during foam flooding. A
new empirical model was developed in this paper by adding a flow equation for surfactant element. The new model was proved to be more effective because of the less empirical data re-quired, lower calculation cost and simpler and faster screening process.

Key words: foam flooding, improved oil recovery, mobili-ty control, prediction model
