ACTive MSAR

The ACTive™ multicycle system for actuated response (MSAR) is part of the ACTive real-time downhole coiled tubing services. Designed to bring greater operational flexibility to downhole tools, the MSAR enables on-demand selective actuation of hydraulic tools, such as third-party hydraulic tractors for extended-reach applications. This tool communicates with the ACTive electrical multilateral module (eMLT) and integrates with the ACTive direction and inclination (D&I) module. The eMLT and D&I modules precisely steer the bottomhole assembly (BHA) into laterals using electrical commands alone, eliminating the need for fluid pumping.

Enhanced performance and efficiency

The ACTive MSAR leverages the full suite of ACTive services’ downhole measurements, enabling real-time mapping of lateral wells, quick lateral entry, and extended matrix stimulations with pinpoint accuracy. By decoupling hydraulic functionality from BHA operational mode switching, MSAR provides faster, more efficient downhole adjustments that simplify operations and enhance overall efficacy.

Key benefits for complex operations

The ACTive MSAR is crucial for enabling complex CT BHAs, combining both electrically and hydraulically actuated downhole tools without compromising functionality. Its selective control results in more effective operations, often reducing the number of runs. With MSAR, operators can use multilateral tools and hydraulic tractors for matrix stimulation in extended-reach, multilateral wells in a single run—eliminating the need to drop a ball to activate a circulation valve above the tractor or to search for specific pressure windows before pumping acid.

Versatile application in multilateral and stimulation workflows

The ACTive MSAR’s versatile design supports a range of downhole workflows, such as

• multilateral well stimulation, using a combination of multilateral tools and high-pressure jetting
• pumping fiber-laden diverters while maintaining a high-pressure jetting tool for effective matrix treatment placements
• rigless plug and abandonment workflows, hybrid mechanical-chemical conformance, and perforating with jetting in a single run.

The MSAR consists of two primary components:

• Actuator with telemetry and sensors: Contains electronics for real-time communication and sensors that monitor downhole operations.
• Application-specific adapter (circulating valve): Redirects fluid flow between the annulus and downstream assembly, as needed, without requiring surface returns or stopping operations.

During intervention, the MSAR toggles the valve between two states. In the first state, flow is directed to the annulus through user-replaceable nozzles (variable sizes support circulation or jetting). In the second, flow is directed to the downstream assembly. The CT operator initiates each shift via software, activating the downhole motor to toggle the piston. Downhole sensors confirm the shift, stopping the motor and providing the operator feedback.

Reliable, power-free state maintenance and contingency controls

The valve holds its current position regardless of downhole conditions like temperature, shock, pressure, or flow rate, without consuming power. In the unlikely event a manual intervention is required, operators can send a metal ball down the CT pipe to shift the valve through applied surface pressure. The ACTive service software continuously monitors tool health by tracking downhole sensors, ensuring reliable performance and maintenance insights.
