    Abstract

    Asphaltene precipitation is an important phenomena faced during oil production that causes many problems such as plugging the reservoirs, production wells and transmission pipelines. Therefore, it is necessary to predict the asphaltene precipitated as a function of temperature and pressure. The aim of this study is to investigate the effect of pressure and temperature on the asphaltene precipitation in an Iranian oil reservoir. For this reservoir, the heaviest component is spillited and regrouped with a Commercial PVT Modelling Software. The new heaviest component is divided into precipitating and non-precipitating components. Equation of state (EOS) is tuned by using experimental data including constant composition expansion (CCE), differential liberation (DL) and separator tests. The results of stability analysis show that there is a high risk of asphaltene precipitation in this reservoir. Maximum amount of asphaltene precipitation occurs around the saturation pressure. It is also observed that asphaltene precipitation is increased by decreasing the temperature along the production wells and transmission pipe-lines.
