Empirical PVT Correlations commonly used in the oil industry are important tools for the reservoir-performance calculations. The Oil Formation Volume Factor (OFVF) or (Bo) considered one of most important key factors in reservoir and production engineering calculations. Different OFVF correlations are proposed in the literature to estimate the OFVF in the absence of the lab measure OFVF. Most of those correlations are depending on such properties as reservoir temperature T, gas solubility Rs, oil specific gravity γo, and gas specific gravity γg. This study evaluated the following eight empirical correlations for estimating the oil formation volume factor Bo below the bubble point pressure: Standing’s Correlation (1947), Glaso’s Correlation (1980), Marhoun’s Correlation (1988), Petrosky - Farshad’s Correlation (1993), Kartoatmodjo and Schmidt Correlation (1994), Almehaideb Correlation (1997), Alshammasi Correlation (1999), and Alsharkawy and Alikhan (1997). (220) data point below the bubble point pressure from twenty-eight wells were selected from seven Libyan oilfields to perform this study. This evaluation study adopted the calculation of the absolute average relative error AARE, regression coefficient R2, and the standard deviation STDEV. The results showed that Almarhoun’s correlation gives the lowest Average Absolute Relative Error of 1.1% with lowest Standard Deviation of 0.923 and the highest correlation coefficient (R2) 0.9643. |
