Commingling multiple zones under a single Electric Submersible Pump (ESP) offers clear advantages over conventional solutions for draining multiple reservoirs. The conventional approach involves drilling a well for each zone or installing multiple ESPs on one well with individual tubing to the surface. The challenge with commingling multiple zones is controlling how one zone is produced relative to the others. Using a remotely controlled choke in combination with tubing and annulus pressure gauges and flow meters makes it possible to optimize the production of each zone independently. This innovative application of intelligent well technology allows the operator to manage the depletion of each zone without interventions
