Well intervention is a demanding operation, particularly in mature reservoirs where evolving well conditions require precise execution. Extended-reach wells, multilaterals, and integrated operations demand more accuracy than traditional methods can deliver. Pressure-based actuation and mechanical sequencing often introduce uncertainty—making it harder to execute tasks at the right depth and time.
Without real-time visibility and control, operations become less efficient and more prone to NPT and missed objectives. Conventional approaches often require multiple runs and manual adjustments, increasing risk, cost, and variability—and limiting the ability to complete complex interventions in a single trip.
As the industry focuses on efficiency, repeatability, and performance certainty, precision and control are now essential. Real-time measurement, command, and actuation reduce uncertainty and help ensure every intervention achieves its full potential.
ExaCT™ electrical downhole CT control system replaces passive, pressure-dependent actuation and mechanical sequencing with active electrical control. Continuous downhole feedback gives operators the real-time visibility to execute tasks at the right depth and at the right time, removing the uncertainty that pressure-based methods introduce in extended-reach, multilateral, and integrated well programs.
By integrating power, telemetry, measurement, and actuation into a single electrical architecture, the ExaCT system activates tools precisely at target depth and changes operational modes without tripping. Operators execute with confidence and achieve the predictable outcomes that well programs focused on efficiency and performance demand.
Designed for harsh downhole conditions, including sour, corrosive, and high-temperature environments, the ExaCT system delivers standardized, repeatable, push-button workflows. Operators gain the execution confidence and predictable outcomes that efficiency- and performance-focused well programs demand.

Unlike conventional systems that depend on pressure cycling and mechanical sequencing, the ExaCT system uses electrical control and real-time telemetry to provide direct command, immediate feedback, and precise execution of downhole operations.
The ExaCT system improves efficiency by enabling push-button control of downhole tools, reducing the need for multiple trips, minimizing fluid usage, and optimizing operations through real-time measurement and actuation.
CT is used to perform well intervention operations without removing the completion. Common applications include well cleanouts, nitrogen lifting, logging, perforating, stimulation, milling, fishing, and mechanical interventions. CT enables efficient access to producing wells while minimizing downtime and operational risk.
Electrical CT combines conventional CT conveyance with real-time power and data transmission to downhole tools. This enables live monitoring, downhole control, logging, perforating, and tractor operations in a single run, improving operational efficiency and reducing intervention uncertainty.
Operators often select coiled tubing when wellbore circulation, fluid pumping, mechanical force, or continuous pipe conveyance is required. CT is particularly effective for cleanouts, stimulation, milling, and interventions in highly deviated or horizontal wells where conventional wireline operations may be limited.
