Abstract: Liquid density is one of the most important governing physical parameter of the fluid flow. Generally, oil density measured at standard conditions (14.65 psia and 60 °F) via Density Meter. Since there is a remarkable difference between calculated density from compositional analysis and measured one at standard conditions. So it is of great importance to use an accurate correlation to calculate the oil density at standard conditions. The proposed correlation correlates measured density with measured molecular weight, calculated molecular weight and calculated density which calculated from compositional analysis. Here, based on measured Egyptian oil reservoirs data; new correlation has been developed for prediction of oil density at standard conditions (14.65 psia and 60 °F). Validity and accuracy of this correlation has been confirmed by comparing the obtained results of this correlation with experimental data for Egyptian oil samples. Checking the results of this correlation shows that the developed correlation results are in a high agreement with the experimental data.
