Study of the dynamic behavior of an AICD using a digital twin.

Solutions aiming to reduce water production in heavy oil wells have led to the design of devices known as Rate Controlled Production (RCP) Autonomous Inflow Control Device (AICD) Valves placed in well completions that autonomously opens with the oil inflow and closes with water by choking the flow. These devices are based on Bernoulli's principle using a levitating disk that chokes the flow of the phase with the lowest flow resistance. In this study, a numerical model based on the Computational Fluid Dynamics (CFD) technology is proposed to understand these devices' operations, aiming to propose better designs without experimentation. The numerical model is based on the Dynamic Fluid-Body Interaction (DFBI) and the Volume of Fluid (VOF) physical models. The model was found to respond as expected depending on the physical properties of the fluids involved in heavy oil production. Finally, some limitations have been found from the numerical study that can be improved in future studies.
