Borehole-casing

Borehole-casing probes for downhole examination and evaluation

Borehole-casing logging probes provide continuous logs of borehole diameter, inclination, and azimuth. Sonic probes are available for cement bond log casing integrity checks and for cavity mapping in large fluid filled shafts, caverns and voids.

3-arm caliper borehole-casing probes
3-Arm Caliper

The 3-Arm Caliper probe provides a single continuous log of borehole diameter as recorded by three mechanically coupled arms in contact with the borehole wall.

Gyro borehole-casing probes
Gyro

The Gyro probe acquires borehole inclination/azimuth logs in situations where metal casing or magnetic materials around the borehole prevent use of the standard verticality probe.

Borehole geometry borehole-casing probes
Borehole Geometry

The Borehole Geometry probe consists of a 4-arm caliper combined with a verticality measurement.

Full waveform sonic / CBL borehole-casing probes
Full Waveform Sonic/CBL

The Full Waveform Sonic probe uses a dual-transmitter dual-receiver array to provide high quality formation acoustic-velocity data.

Verticality borehole-casing probes
Verticality

The Verticality probe provides accurate, continuous measurements of borehole inclination and direction.

Sonar caliper borehole-casing probes
Sonar Caliper

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.
