Thermodynamically Investigation of MiS Oilfield in South of Iran

The goal of this study is presents the research data on the influence of the adiabatic and the Joule Thomson effects and the heat of fluid degassing on the temperature field in the porous medium of South Iran Oilfields. To calculate the formation of the temperature field with due account taken of the above effects one has to know thermodynamic coefficient for actual formation fluids. With this aim in view, an experimental installation was developed based on the PVT Cell and analysis of data is done through using Eclipse TM to determine the coefficients of the JouleThomson and the adiabatic effects, as well as to obtain the specific heat of oil degassing. The thermodynamic coefficients thus obtained are used for investigating a nonstationary temperature field in the porous medium for various conditions of pressure gradient and the content of gas dissolved in the fluid.
