Abstract: The laterals of a smart multilateral completion are divided into a number of compartments for improved monitoring and controlling of unwanted fluid production. The productivity index (PI) of each compartment is determined by conducting downhole tests utilizing the downhole liquid metering, real-time pressure measurements, and the electrical inflow control valve (ICV). The PIs and other testing results are used to calibrate a multiphase single well simulation model to select the optimum ICV opening setting at each compartment. The calibrated simulation model is used in a fluid dynamic simulator (e.g., PIPESIM) to generate simulation results based on different ICV opening settings. The optimum ICV opening setting is selected based on the simulated well production delivering the target oil rate while satisfying the constraints of (i) the maximum allowable liquid production rate from each compartment and (ii) the maximum allowable reservoir pressure drawdown all the compartments combined.
