Design and Validation of a Digital Twin to the Intelligent Well Completion

The intelligent completion (IC) has been implemented in new oil wells, especially in the pre-salt exploration areas. One of the most relevant components is the Interval Control Valve (ICV), responsible to execute the switching between production zones. The use of ICVs is critical to the O&G completion and drawbacks in their operation can lead to productive losses. Given the hard and costly maintenance, it is fundamental to have means for diagnosis and prognosis of this component. Digital twin (DT) has been increasingly researched for emulating physical assets in a computational environment, in order to understand their behavior in several operation conditions and carry out failure analyses. The present work develops a DT for a hydraulic ICV system, considering simulations of ICV normal and anomalous operation, comparing with open-source databases. The DT includes modeling of hydraulics and thermal exchanges phenomena, as well as different control sequences applied to the valve systems.
