Abstract Conventional downhole tool actuation methods rely on drop balls, flow rate changes, or pressure cycles, all of which disrupt operations and limit flexibility. A rugged, electrically actuated system was developed to overcome these limitations by enabling on-demand mechanical actuation with two-way real-time surface communication. This study outlines the design rationale, initial testing, and operational value of the system, which supports high-rate pumping, milling compatibility, and combined workflows in coiled tubing (CT) interventions. The rugged system uses an electric motor to drive a hydraulic pump, which actuates a piston to redistribute flow between two paths: toward any hydraulically actuated downhole tool (e.g., a motor, mill, or tractor) or towards external nozzles for circulation. The design supports higher flow rates (up to 8 bbl/min) and withstands severe vibration during milling operations. Testing under continuous pumping recorded flow rates and differential pressures during electric flow shifts. The tool maintained continuous circulation, reliable actuation, and two-way communication, and shifted successfully through an agitator in high-vibration environments. Compared with conventional methods, the system eliminates the need to stop pumping or to manipulate flow rates, reducing operational complexity and risk. The rugged design enables workflows previously impractical, such as combining milling and high-rate acidizing in a single run — critical for hard scale removal. Gas expansion during nitrified milling operations presents stall management challenges. The downhole activation system can save at least 1 to 4 hours per stall event. High nitrogen flow rates, which would normally exceed downhole motor capabilities, can be diverted above the motor using electrical activation, reducing sweeping lengths by up to 80%. For multilateral stimulation, the technology reduces acidizing time by up to 50% (from 80 hours to 40 hours) compared to the slim electrically actuated version and saves approximately 1,600 bbl of water per job compared to methods leveraging flow-actuated multilateral discovery tools. This study benefits CT engineers and operators seeking to reduce downtime and improve efficiency in milling, cleanout, and stimulation workflows. The novelty lies in ruggedizing an electrically actuated downhole flow diversion tool to manage high flow rates and severe vibration — capabilities absent in the slim version. By enabling combined operations in a single run and eliminating hydraulic triggers, the technology simplifies intervention, reduces complexity, and makes previously impractical jobs achievable in challenging well environments.
