Abstract

—Asphaltene deposition in wellbores/pipelines causes serious production losses in the oil and gas industry. This work presents a numerical model to predict asphaltene deposition in\ud wellbores/pipelines. This model consists of two modules: a Thermodynamic Module and a Transport Module. The Thermodynamic Module models asphaltene precipitation using the Peng-Robinson Equation of State with Peneloux volume translation (PR-Peneloux EOS). The Transport Module covers the modeling of fluid transport, asphaltene particle transport and asphaltene deposition. These\ud modules are combined via a thermodynamic properties lookup-table generated by the Thermodynamic Module prior to simulation. In this\ud work, the Transport Module and the Thermodynamic Module are first verified and validated separately. Then, the integrated model is\ud applied to an oilfield case with asphaltene deposition problem where a reasonably accurate prediction of asphaltene deposit profile is\ud achieved
