In this article asphaltene precipitation models are described and in a case study the precipitated asphaltene is represented by an improved solid model. The main purpose of this study is to model andanticipate the effects of major parameters on formation of asphaltene precipitation and deposition atreservoir conditions, in order to provide a better understanding of the factors that may enhance asphaltene precipitation or deposition. The oil and gas phases are modeled with Peng-Robinson equation of state. The effect of several factors such as solid molar volume and injected solvent gas composition aswell as thermodynamic condition variations (such as pressure and temperature) on the predictions made by this model will be investigated too. Eventually, with regard to the experimental data that has been obtained from one of the oil wells located at the South Oil Zones of Iran’s oilfields, the accuracy ofmodeling and anticipating of asphaltene precipitation will be checked. All of the related calculations have been done by Winprop software from CMG package
