Borehole structure logging provides detailed information on the structure of borehole formations by means of optical imaging, acoustic imaging, resistivity imaging and from the application of pressure to the borehole wall. These probes find applications in geotechnical investigation as well as for determination of the geometry of shafts, caverns, trench pits and voids.
The High Resolution Acoustic Televiewer (HRAT)® provides a continuous high-resolution oriented ultrasound image of the borehole wall.
The 4-Arm Dipmeter measures microresistivity and tool orientation data. These can be processed to determine formation dips.
The Elastmeter is a borehole lateral load tester designed to figure out deformation characteristics of the ground ranging from soft rock to hard rock.
The High Resolution Optical Televiewer (Hi-OPTV)® provides a continuous very high resolution oriented image of the borehole walls using a conventional light source.
The Sonar Caliper Probe has been developed to provide a scaled and orientated cross-section of large bores, shafts, caverns and trench walls; combining accurate diameter measurement with a fully orientated 360° view of its surroundings.
Four-core 3,000m (10,000ft) high speed wireline borehole camera system operating on a 4-core or coaxial cable at a high transmission.
The 4-Arm Caliper has an advantage where the borehole cross-section deviates from circular and provides a single continuous log of borehole diameter as recorded by two independent pairs of linked arms in contact with the borehole wall.
