Developing of an Empirical Bubble Point pressure Correlation

Bubble point pressure is an important reservoir fluid property. Ideally, Bubble point pressure is determined experimentally in the laboratory; However, this value is not always available and correlations are consequently used to determine it. At this work, first the published bubble point pressure are reviewed and then a new correlation is developed to estimate bubble point pressure of crude oils in Iranian. This correlation is applicable for crude oils of API ranging between 19 to 45.The comparison of this new correlation with other published ones shows that it is much more accurate than the other ones. The average absolute deviation error (percent) of the new correlation is about 6.35%.
