Abstract: A major goal when using a horizontal well is to increase the productivity rate when compared to the vertical layout, due to a larger area of the reservoir exposed to the well. The coupled solution into the reservoir and through the well requires finding the answer to the Darcy equation in the reservoir and the Navier-Stokes equations in the well. Additionally, several types of completion, which introduce new flow resistances, such as completions with inflow control device (ICD), stinger completion, packed off, gravel pack, and slotted liner are considered. All these details are not available with the current reservoir simulators, since the level of local detail would require a very large computational time and a complex model. In this work, the coupling between the reservoir and the well is accomplished through a distributed system, where the flow, at various types of completion, is handled through correlations obtained analytically or provided by completion equipment manufacturers. The proposed procedure consists of a fast tool, accurate and easy to use for a petroleum engineer. The results of this work show that the distributed system allows a detailed view of the flow into the well and its completion, quantifying the flow rate and pressure over the annular and liner for different types of completion, adding more physics into these simulations.
