INFLOW PERFORMANCE

The Inflow Performance Relationship (IPR) describes the behavior of a well’s pressure and quantifies its production rate. In the petroleum industry, various IPR correlations exist today, with the most commonly used models being those of Vogel and Fetkovich.In this work, a new model was developed to predict the IPR curve using a new correlation that accurately describes the behavior of a well’s flow rate as a function of the average reservoir pressure. This new correlation was obtained using actual field cases.After the development of the new model, its validity was tested by comparing its accuracy with that of the most common IPR models, such as Vogel, Fetkovich, and Wiggins. The results of this comparison showed that the newly developed model gave the best accuracy, with an absolute error of 5.54%. The other models were ranked according to their accuracy as follows: Fetkovich, Vogel, and Wiggins, with absolute errors of 6.73%, 23.18%, and 32.3%, respectively.
