Abstract An inflow performance relationship describes the relationship between the well production rate as a function of driving force in reservoir which is the differential pressure between average reservoir pressure and the well bottomhole flowing pressure. When there is two-phase flow in the reservoir, we need to use an empirical correlation to represent this relationship. The objective of this study is to evaluate five IPRs proposed in the literature for predicting individual oil well performance which are Vogel, Fetkovich, Jones et al., Kilns & Marcher, and Sukarno & Wisnogroho. The evaluation of IPR correlations is done by comparing the bottom-hole pressure obtained from ECLIPSE100 simulation with the calculated bottom-hole pressure from IPR correlations in order to gain an understanding of their accuracy and reliability for solution gas drive reservoirs.As a result, the average and standard deviation of Mean Absolute Percentage Error (MAPE) between the simulated pressure (ECLIPSE100) and the calculated pressure for the five IPR correlations show that Jones et al.’s correlation gives the best value while Fetkovich, Vogel, Sukarno and Wisnogroho, and Klins and Majcher follow in less accurate order. Overall, MAPE tends to decrease significantly for every IPR correlations when the absolute permeability increases. In addition, an individual IPR correlation has more accuracy and precision at one aspect reservoir but not at the other conditions.
