In the current oil and gas environment, operators have focused on production optimization, effectively squeezing every last drop of oil out of their wells. Autonomous Inflow Control Device (AICD) technology has been deployed as part of the completion in old and new wells resulting in increased oil production by reducing water and gas production. For many years, inflow control devices (ICD), which restrict flow by creating additional pressure, have been used to mitigate this problem. They are however, passive in nature and after the onset of water or gas breakthrough, the choke effect cannot be adjusted without intervention.
The AICD is an active inflow control device with a self-adjustable design to self-regulate and provide greater choke when an unfavorable fluid such as gas and water ingress. This prevents the well from being flooded when unwanted fluids breakthrough, therefore providing the advantage of being able to even out the inflow into well. In addition, it will also choke the unfavorable breakthrough sections of the well and producing from remaining sections leading to greater recovery, lower water, and gas production.
This technology has helped improve recovery in horizontal well across the globe by reducing gas-oil ratio or water cut of the well, thus increasing ultimate oil recovery. The key factor to successful application is a systematic approach in prediction modeling and well design workflow to select a well candidate between Passive and Autonomous inflow control device.
Dr. Ismarullizam Mohd Ismail is the Subsurface Engineering Manager for Tendeka based in Aberdeen, United Kingdom. He received a MSc. and Ph.D. in Mechanical Engineering from the University of Leeds, United Kingdom. He has been working in sand control and inflow control technology for over 15 years in multiple roles, mainly in offshore operation, project engineering and product development. His current work involves developing new inflow control technology, subsurface modeling and managing an inflow control product line. He has designed and modeled AICD/ICD nozzle completions for more than 100 wells across the globe and he also holds various patents for inflow control design. Prior to joining Tendeka, Dr Mohd Ismail worked for various major service companies and carried out university research.
