Capture true structural detail with a high-definition optical televiewer, equipped with precision imaging and orientation sensors to deliver accurate, reliable borehole insights across diverse geological conditions.
In mining and geotechnical operations, poor borehole visibility is more than a technical issue. It’s a costly barrier to accurate interpretation. When imaging lacks clarity, geological features become difficult to define, structural analysis loses reliability, and project timelines extend unnecessarily.
Traditional inspection methods struggle in varying borehole conditions, producing low-resolution visuals and incomplete orientation data, leading to misinterpretation, repeated surveys, and uncertainty in your geological results.
The Optical Televiewer eliminates uncertainty by delivering clear, high-resolution borehole imaging with precise orientation data. Powered by advanced optical and sensor technology, it captures continuous visual data in real time, even in challenging geological conditions.
Whether your borehole is dry, water-filled, vertical, or angled, the Optical Televiewer ensures every image is detailed, traceable, and easy to interpret.
The result? Reliable structural insights, faster geological analysis, and reduced operational costs.
Captures detailed 360° borehole images with true-color clarity.
Delivers accurate dip and azimuth data for structural analysis.
Integrated magnetometers and accelerometers ensure reliable orientation.
Operates in dry and water-filled holes across varied diameters.
Supports fracture detection and lithology characterization.
Adds lithological data for enhanced interpretation and correlation.
