Achieving reliable well intervention outcomes requires more than access—it requires precision, control, and confidence in every operation.
Our CT intervention services integrate advanced technologies, real-time insight, and engineered workflows to reduce uncertainty and improve execution across complex well environments. The result is greater operational consistency, optimized performance, and better-informed decisions throughout the life of the well.
These services support a wide range of intervention applications, including well cleanout, scale removal, stimulation support, logging and diagnostics, perforating, and mechanical operations. By combining fit-for-purpose tools with real-time data, each intervention is executed with greater accuracy and efficiency.
An operator on the Norwegian Continental Shelf increased oil production from 780 bbl/d to 1,500 bbl/d and saved 7 days of rig time.
A Middle East sour gas operator increased gas production by approximately 30% and reduced intervention cost by more than 20% using underbalanced live descaling.
An onshore UAE operator reduced water production by approximately 479 bbl/d, lowering water cut from 47.3% to 11.5%.
At Clair Ridge in the UK North Sea, bp used powered downhole measurements during reverse-circulation cleanout to improve pressure control and detect screenout earlier.
At the center of this approach are ACTive™ real-time downhole coiled tubing services and the ExaCT™ electrical downhole CT control system. ACTive services provide continuous downhole power, real-time telemetry, and measurement capability, delivering critical downhole data and operational visibility.
Building on this foundation, the ExaCT system enables real-time precision, control, and greater certainty in CT interventions through electrical actuation, selective tool control, and integrated workflows across ExaCT access, cleanout, logging, shifting, isolation, and fishing services.
Together, ACTive services and the ExaCT system enable operators to measure, decide, act, and verify in real time, improving execution quality and reducing operational uncertainty.
Maintain continuous operations while improving cleanout efficiency and control.
Optimize CT stimulation matrix using live monitoring of injection rate, downhole pressure, and temperature.
Ensure target zone coverage with selective perforating and achieve accurate depth control in a single run.
Quantify the intake profile of treatment fluid along the wellbore.
Deploy and maintain artificial lift systems, improving production and well performance with minimal disruption.
Increase production and extend well life by accessing bypassed reserves through live-well directional reentry drilling.
Perforate, stimulate, and fracture multiple zones in single-field operations.
SLB combines CT engineering expertise with an integrated portfolio of tools, real-time downhole measurements, and fit-for-purpose equipment to help operators plan and execute interventions more efficiently.
CT can be used for wellbore cleanout, stimulation, logging, perforating, nitrogen kickoff, circulation, cementing, sand control, and mechanical isolation. Because CT is continuous and spoolable, it enables intervention in live wells without using a conventional workover rig.
Real-time downhole measurements are valuable when pressure control, treatment placement, depth correlation, or changing well conditions affect execution. Live pressure, temperature, flow, and tool-position data enable teams to evaluate and adjust the intervention while it is underway. In applicable workflows, this visibility can help complete evaluation and treatment in one trip.
Reverse-circulation cleanout routes debris and returns through the CT string, helping manage bottomhole pressure and reduce circulating-fluid volumes. It can be particularly useful in complex, depleted, or pressure-sensitive wells. At Clair Ridge, real-time downhole measurements enabled pressure management, early screenout detection, and adjustments to reverse-circulation parameters during the cleanout.
Results depend on the well conditions and intervention objective. Documented SLB applications have increased oil production from 780 to 1,500 bbl/d, increased sour-gas production by up to 30%, and reduced water cut from 47.3% to 11.5%, achieving a positive return on investment within five days.
