Development of Simple Correlation to Evaluate Formation Volume Factor for Nigerian Crude Oil

Accurate reservoir fluid characterization is vital to understanding the flow behavior in the reservoir and proper quantification of reservoir productivity. This study developed a correlation for formation volume factor for Niger Delta crude oil and evaluated the necessity of using locally developed correlation in evaluation of the formation volume factor (Bo). Reservoir fluid data collected from Niger Delta were used to develop correlation for Bo. The result from the model was used to match Laboratory PVT derived Bo and also compared it with existing universal models. The new model had better prediction of Bo. The new correlation can be used for a quick prediction of Bo in the absence of laboratory PVT data.
