Inflow Performance Relationship (IPR) of a well is the relation between the production rate and flowing bottom hole pressure. The IPR curve represents the ability of reservoir to estimate production optimization devices such as tubing size, choke, required for designing well completions, optimizing well production, and designing artificial lift. It is rare to find a reservoir being produced from only a single well. A field usually contains several wells producing from the same drainage domain, and each well will have an effect on the pressure at the other well. Each wells will have their own drainage area depend on wells distance, the rock and fluid properties. The flowing bottom hole pressure will determine the drainage area of each wells. <br /> <br /> <br /> Nowadays, Future Inflow Performance Relationship of wells is developed by a single well model, the production of surrounding wells was not a consideration. In this work, a new model to predict IPR future curve was developed, using the behavior of production rate. This condition is represented by a reservoir-multi producing wells solution gas-drive which is developed by CMG simulator. Reservoir pressure is bellow bubble point pressure and in two phase flow. <br /> <br /> <br /> After the development of new model, its validity was tested and comparing with that of the most common IPR models such as Vogel13, Standing10, Fetkovich4, Klins7, Wiggins14, Sukarno11 and future IPR such as Eickmeier2, Sukarno11, and Wiggins14. The proposed IPR and proposed future IPR equations provide a reasonably accurate yield to evaluate the performance of multiwells system. The production from surrounding wells affects to the future IPR, but still needs surrounding wells historical data. The proposed IPR and future IPR equations did not approach the Vogel13 IPR equation. The Wiggins14 IPR and future IPR gives maximum production rate than any other equations.
