The performance of oil wells producing water during boundary-dominated flow was investigated to develop a better understanding of multiphase flow and its effects on single well performance. This understanding can assist the petroleum engineer in predicting the pressure-production behavior of oil wells producing under boundary-dominated flow conditions.
An analytical Vogel-type inflow performance relationships (TPR) was developed from the multiphase flow equations. This relationship is based on the physical nature of the multiphase flow system and contributes to a better understanding of the pressure-production behavior of an individual well. The analytical IPR was verified using simulator information for three-phase flow. The analytical IPR provides a method for the petroleum engineer to develop individual IPRs for each reservoir.
