3 ARM

CALLIPER SONDE

The Three-Arms caliper sonde  is a popular choice for bore hole diameter logging and borehole volume calculation. Like other sondes,  all the calipers can be run on their own or they can be screwed together to run as one single tool string.

4 ARM

CALIPER SONDE

The Four-Arm caliper is particularly useful in large boreholes. Working either in 4 radii (r1, r2, r3, r4) mode or in two diameters (d1, d2) mode, this sonde can provide an accurate bore hole geometry profile as well as bore hole volume.
