In this research, the individual performance of vertical oil wells are investigated. The objective of this study was to verify the suitability of certain empirical relations to predict the rate-pressure behavior of a single oil well producing from solution-gas drive reservoirs. Inflow performance curves were generated for 26 cases based on actual field data. The predicted rates where then compared to actual measured rate and pressure data. The variation between the measured and predicted rates by the various methods studied has been analyzed. Based on this analysis, multipoint performance methods generally provide the most reliable estimates of well performance. Fetkovich' s multipoint method was the most consistent performance predictionfor the cases studied. In addition, it was observed that no one method presented the best results for all cases and it is recommended that multipoint performance methods be utilized to yield a range of potential pressure-production behavior.
