Intelligent completions (IC) incorporate permanent downhole sensors and surface-controlled downhole flow control valves, enabling engineers to monitor, evaluate, and actively manage production in real time without any well interventions. Data is transmitted to surface for local or remote monitoring.
Traditional IC systems cannot be deployed in extended reach wells or in the multilateral well branches that today’s drilling technology facilitates. They lack sufficient real-time measurements in individual producing zones to facilitate “cause and effect” decision making. Without detailed compartmental information and control in case of water or gas breakthrough, operators are forced to restrict production, intervene, and in some instances work over the entire well.
Until recently, there has been no way to maintain production from other unaffected zones during the long diagnostic process of production logging, well testing, interpretation, and execution of an appropriate well intervention. Now thanks to a step-change in intelligent completion systems this is no longer the case.
An industry article in the Journal of Petroleum Technology “New Intelligent Completion System Enables Compartment-Level Control in Multilateral Wells” highlights the future of digital recovery—an innovative production and reservoir management system that provides downhole permanent monitoring and in-lateral flow control of multiple zones in real time—for the first time, even in multilateral wells. The article includes a case study from the Middle East.
