The seek for higher efficiency, reliable systems, and carbon footprint reduction is a trend in the Oil and Gas (OandG) industry. Intelligent Well Completion (IWC) has become a widely adopted and the Inflow/Interval Control Valve (ICV) plays a significant role in controlling production and injection flow rates. Electrification of OandG assets, including the IWC tools, offers a dual benefit of increased recovery factors and alignment with global decarbonization efforts. To develop an Electric ICV, the design of an electromechanical actuator capable of operating under challenging conditions and electrical power limitations is required. This dissertation presents the design and testing of an electromechanical actuator in a full-scale prototype Electric ICV. The actuator s performance was assessed through a combination of mathematical modeling and empirical testing under various operational conditions, including high and low temperatures and differential pressures. Key findings from this research demonstrated that the mathematical model effectively supported the actuator s design, with calculated results aligning closely with functional tests at room temperature and zero differential pressure.
