First, the experiment and modeling for Foamy oil flow are presented. The experiment part includes the observations of pseudo bubble point pressure and foamy oil PVT characteristics. The model formulation mainly includes governing equations for the dead oil component and overall gas component, state equations of foamy oil density and additional condition of saturation constraint. Two case studies are performed by using heavy oils of Orinoco, Venezuela and Marinza, Albania. It is concluded that the pseudo bubble point model can present foamy oil behavior, and the simulation results indicate the three stages of cold production under foamy oil flow.
