HOUSTON -- Schlumberger has released a new family of live downhole coiled-tubing services called ACTive. According to the company, these services provide innovative interventions to elevate the performance, efficiency, and results of coiled-tubing operations in various types of well configurations.

A high-bandwidth fiber-optic cable deployed inside the coiled-tubing string connects bottomhole sensors with surface monitors and controls, allowing for real-time communication.

The ACTive portfolio is composed of six services:
- ACTive Matrix monitors injection rates, downhole pressures, and temperatures of matrix treatments to maximize fluid penetration and coverage, enhance diversion, and optimize treatment volumes.
- ACTive Cleanout uses differential pressure readings to avoid formation damage and minimize the number of trips and operating time, while ensuring thorough removal of fill.
- ACTive Perf achieves accurate depth control and target coverage in a single run while controlling hydrostatic balance to minimize formation damage.
- ACTive Isolation ensures efficient, on-depth setting of isolation devices in a single run, controlling differential pressure across the sealing elements to ensure their integrity.
- ACTive Lift improves the efficiency and results of nitrogen lift jobs by continuous monitoring and balancing of wellbore pressure while avoiding solids production.
- ACTive Profiling enhances all ACTive services by including distributed temperature surveying (DTS) to provide a 3D time/temperature profile across the entire well to monitor treatment placement and production performance.
