Abstract :
In this paper, a simplified formulation for a compositional reservoir simulator is presented. These type of simulators are used when interphase mass transfer depends on phase composition as well as pressure. The procedure for solving compositional model equations is completely described. The Peng Robinson equation of state is used for preparing a compositional thermodynamic program for equilibrium calculation, property estimation and pseudo component determination. Another purpose of this paper is to prepare an experimental apparatus for the displacement of oil by gas injection. In each test, oil recovery as a function of injected pore volume was measured. The application of the developed simulator to simulate the results of the oil recovery from slim tube experiments is also presented. Finally, the model was run for a 2-Dreservoir. Acceptable trends were obtained from the model predictions.
