In a dual-lateral well, traditional hydraulic tools for mapping, cleanout, and stimulation would have required multiple runs and excessive water and time. The ACTive™ multilateral stimulation service enabled faster lateral entry, fewer runs, and significant water and emissions savings.

An operator in the Middle East faced considerable challenges in performing efficient dual-lateral mapping and stimulation. Traditional cleanout and stimulation work required multiple runs, leading to increased costs and downtime. Additionally, typical hydraulic multilateral entry tools demanded over 500 barrels of water per lateral and involved lengthy mapping times. The goal was to streamline operations, complete the entire cleanout and stimulation scope in fewer runs, and reduce water consumption. A solution that cut down on overall running footage, saved time, and minimized environmental impact was essential to optimizing the dual-lateral well's productivity.

SLB recommended its ACTive multilateral stimulation service, part of the proven ACTive real-time downhole coiled tubing (CT) services. It features several modules—the ACTive multicycle system for actuated response (MSAR), acid‑compatible electrical multilateral (eMLT) module, and direction and inclination (D&I) module. The service provided rapid mapping, quick access to each lateral, and a single‑run cleanout and stimulation across multiple laterals. Continuous power and real-time downhole telemetry were enabled through ACTive powered downhole measurements system.

The ACTive service reduced lateral entry time to less than 20 minutes, and the full cleanout and stimulation scope was completed in a single CT run. By consolidating operations, this approach saved at least 48 hours in operation time, decreased CT running footage by nearly 20%, conserved more than 1,000 bbl of water, and cut CO2 emissions by approximately 25%. This fully electrical solution proved to be efficient, cost‑effective, and ecologically sound, setting a new standard for multilateral well interventions.
