MULTIBARRIER CORROSION
“Seeing Through Layers. Understanding Structural Health”
MultiBarrier Corrosion Technology offers a powerful diagnostic solution for assessing the structural condition of casing and tubing in cased-hole environments. Using an electromagnetic impulse method, the tool measures wall thickness across multiple pipe barriers.
The tool operates by emitting controlled electromagnetic impulses into the wellbore environment. As these impulses interact with the surrounding steel mass, they generate a response profile determined by the cumulative wall thickness of each barrier. Corrosion, metal loss, or deformation introduces detectable variations in the signal response.
Advanced signal processing algorithms then analyze the data to identify zones of structural degradation. The result is a clear profile of metal loss across multiple pipe barriers, providing operators with the insight needed to plan repairs, prioritize interventions, and preserve well integrity over time.

Custom Tool Design and Telemetry Integration
The technology can be delivered as a standalone or combined system, custom-built to include specific sensors required by the client and designed for compatibility with proprietary downhole telemetry platforms.
INTEGRATIONS:
Multi-Barrier Corrosion Technology is fully compatible with a wide range of downhole diagnostics and logging platforms. It is commonly deployed alongside:
Spectral Noise Logging
To correlate structural damage with dynamic leak activity.
High-Precision Temperature (HPT) Logging
To detect thermal anomalies linked to barrier failure.
Production Logging Tools (PLT)
For integrated flow and integrity profiling. This modular approach supports a multi-physics diagnostic strategy, combining structural, thermal, and flow-based measurements for high-confidence well integrity evaluation
