New correlations estimate P b , FVF

Leonid L. Levitan, Mark Murtha Intercon Westbury, N.Y. EQUATIONS AND NOMENCLATURE [41,389 bytes] PDF FORMAT New semiempirical correlations use dimensionless variables to provide better estimations of bubblepoint pressure (Pb) and formation volume factor (FVF). The new correlations were used in a computer program developed by the authors for well bore hydraulics calculations. The resulting calculations provided a better description of the experimental data than existing models by Aziz1 and Orkiszewski.2 The empirical correlations commonly used to determine Pb and FVF were reviewed to evaluate their accuracy and gain a better understanding of th...
