Knowledge of bubblepoint pressure is one of the important factors in the primary and subsequent developments of an oil field. Bubblepoint pressure is required for material balance calculations, analysis of well performance, reservoir simulation, and production engineering calculations. New bubblepoint pressure correlation based on data from the Niger Delta crude oils has been developed. Both quantitative and qualitative assessments were employed to evaluate this correlation which is compared to the best existing bubblepoint pressure correlation for the Niger Delta crude. The new correlation outperformed the best existing correlation by the statistical parameters used with a rank of 7.3 and better performance plot.
