|Abstract:||Inflow control valves (ICV) can be used to add flexibility to petroleum production operation. They can be used as a reaction of an undesired event (reactive control), like water breakthrough, but they can also be used to prevent or to delay these events (proactive control). Proactive control can be an efficient form to control intelligent wells. However, the benefits of proactive control require an appropriate study to avoid premature decisions that lead to suboptimal results. This paper focuses on the evaluation of the effects caused by ICV operation and its impact on long term field production and cash flow, giving support to tools or equipment to apply proactive controls (use of seismic, sensors etc.). The main objective is to show when possible benefits of a proactive operation can be reached. An inverted five-spot model, representing a specific region of a reservoir, is used to verify the effects of ICV operation, with different production and injection constraints. The results show that proactive control with ICV can, in some cases, improve the performance of the field by increasing oil production and decreasing water production, however, this kind of control is not always profitable. The results also show that ICV shutdowns can significantly alter the behavior of the wells|
