Pressure-volume-temperature Correlations For Iranian Crude Oils

ABSTRACT Pressure-Volume-Temperature (PVT) properties are necessary to reservoir engineering calculations in porous media and it is important for calculations in pipeline as well. This work presents a new set of correlation for estimating Iranian Crude oils properties based on some experimental data. Whenever, these is no representative experimental PVT data, these correlations can be used for oils of API ranging between 19 to 42. New correlations was developed to calculate Oil Formation Volume Factor (Bo), Bubble point pressure (Pb) and solution Gas oil Ratio (Rs). Finally, a comparison is made between these correlations and other published correlations such as Standing, Vazquez & Beggs, Glaso, Farshad and et al, Al Marhoun, Petrosky & Farshad, Hanafi and et al and it is found out that these new correlation are more accurate then the other ones.
