Axial and Sideview Camera Sonde

In air or clean water, the optical televiewer will provide very high-resolution images offering both geotechnical and geological information

In water-filled boreholes, the acoustic televiewer is often the instrument to use because the water is usually opaque.

This televiewer sonde, based on the time and amplitude of reflected sonic pulses, is well suited to various geotechnical applications, since fractures and weak layers are very clearly defined on the image.

The major skill requirement during data processing is the ability to recognise drilling-induced fractures and purge them from the analysis.

Wireline offers the latest televiewer technology from ALT in Luxembourg as well as an advanced dual function camera sonde.
