Cement Bond Logging
Expro’s high-resolution cement bond logging services evaluate barrier quality, confirm zonal isolation and assure compliance – safeguarding well integrity and productivity across the lifecycle.
Sensor-led diagnostics. Data-driven decisions.
We’re continuously evolving our capabilities to deliver more accurate, actionable cement evaluation.
Whether confirming zonal isolation prior to perforation, investigating integrity issues during the production phase or verifying barriers ahead of well decommissioning, our cement evaluation portfolio delivers confidence across the well lifecycle.
As an independent service provider, we draw on best-in-class technologies from selected trusted partners, and are able to offer different types of technologies to support barrier assurance and well integrity surveillance:
- Radial Bond Tools (RBT) - Segmented acoustic receivers deliver a 360° cement quality map, identifying channels, micro-annuli and partial bonding with clarity
- Ultrasonic + CBL/VDL— Combines industry-standard amplitude and variable density logs with high-resolution ultrasonic imaging of the casing/cement/formation interface. This integrated approach provides quantitative cement analysis plus casing wall thickness and corrosion evaluation, assuring both barrier and tubular integrity.
By offering both RBT and Ultrasonic+CBL/VDL, Expro gives operators the flexibility to select the right tool for the well environment, regulatory requirements, and operational objectives — delivering the most complete picture of well integrity available today.
