| Summary: | ³Oil formation volume factor at pressures below the absolute average error of approximately 2%. all these correlations have limitations in predicting the an absolute average error of 1 1.7%. Our approach in analysis of the most popular correlations in the petroleum available. Our only recourse in such cases is the use of average error of 8.4%. A similar reduced variables approach average error on the order of 4%. Similarly, correlating behavior of Rs and Bo at pressures below the bubble-point. bubble-point considered the use of the "reduced" variables bubble-point, B0 In this work we provide a detailed bubblepoint pressure. Our first effort was to correlate Pb- correlation and a pseudo-liquid density correlation correlation for B,, (P< Pb) gave an absolute average error correlation of black oil Pressure-Volume-Temperature (PVT) correlations: Bubble-point pressure, Pb *Solution gas- developed specifically to estimate fluid properties at the developing a new correlation for Rs at pressures below the empirically derived correlations This study considers the equation onto our bubblepoint pressure database we obtained In the practice of petroleum reservoir engineering we are In this effort we tried several relations, but we ultimately literature compared to our two databases (P<Pb, 2213 data many cases no laboratory measurements of properties are often faced with the analysis of processes which require oil-ratio at pressures below the bubble-point, Rs on the order of 2%. We also developed a material balance p, and Rsr' This correlation for Rs (P< Pb) gave an absolute Pb), primarily due to our inability to correlate low points; P= Pb, 728 data points). Our analysis shows that pressure behavior. We instead used Standing's model; this pressure. Specifically, we address the following procedure for the determination of Bo using R, from our new properties for pressures at or below the bubble-point published by McCain and Hill. This correlation also gave an the physical properties of the reservoir fluids, but in these data using our p, correlation we obtained an absolute This is somewhat expected as these correlations were used the "Standing-Petrosky" model. Regressing this was attempted and abandoned for the correlation of B, (P< |
