Oil Formation Volume Factor Empirical Correlations for some Libyan Crude Oils

Abstract

Physical properties of reservoir fluid are
necessary for different field applications. Among those
properties is the Oil Formation Volume Factor (Bo). It is
one of important property for both reservoir and
production engineering. In many situations, laboratory
measurement is not possible either because of
unavailability of liquid oil samples or budget constraints,
Hence, proper empirical correlations to predict formation
volume factor come to rescue. The purpose of this
exploration is to test the performance of the most common
published Oil Formation Volume Factor correlations for
selected Libyan crude oils. Statistical analysis is the
criteria adopted for the evaluation in this study. Cross plot
technique is also applied to check the performance of the
correlation and it gave the same index of the statistical
criteria method.
Accuracy of these correlations has been confirmed by
comparing the obtained results of these correlations with
experimental data gathered from our labs for Libyan oil
reservoirs. It was observed that, there is acceptable
agreement between predicted results with experimental
results.
