Advances (from conventional wells to horizontal and then multi-lateral) in well architecture for maximising reservoir contact have been paralleled by advances in completion equipment development of both Passive Inflow Control Devices (ICDs) and Active Interval Control Valves (ICVs). These devices provide a range of fluid-flow control-options that can enhance the reservoir sweep efficiency and increase reserves. ICVs were initially employed for controlled, commingled production from multiple reservoirs; while ICDs were developed to counteract the Heel-Toe Effect. The variety of their reservoir applications has since proliferated, so that their application areas now overlap. It has become both complex and time consuming to select between ICVs or ICDs for a well’s completion.
