المستخلص: Bubble point pressure is considered as one of the most important PVT properties in petroleum engineering especially in reservoir and production engineering calculation. A numerous empirical derived correlations for estimating the bubble point in the absence of the experimental measured one are proposed in the literature. Three different empirical correlations to estimate the of bubble point pressure to evaluate were selected in this study. Those correlations namely are Standing's correlation, Labedi's correlation and Al-Shammsi's correlation. This study is to make a comparison between these three derived correlations and to evaluate their applicability for some crude oils collected their data from some Libyan oilfields. Forty six well from seventeen Libyan oilfields were selected to perform this study. The results show that Standing's correlation gave the lowest value of both the Average Absolute Relative Error (AARE) and standard division (STDEV) of 7.54% and 6.91% respectively with the highest Coefficient R2 of 0.989.
