Verticality Tool
Accurate Borehole Orientation and Tilt Measurement
The Verticality Tool combines magnetometers and inclinometers to precisely measure the inclination (tilt) and direction (azimuth) of a borehole. It can be operated either centralised or side-walled during data acquisition. The tool calculates the borehole’s position at any depth relative to the log origin, providing X (West-East), Y (South-North), and Z (true depth) coordinates.
While inclination readings are unaffected by steel, azimuth readings can be influenced if steel is present within 1 metre of the borehole. For accurate azimuth measurements, the tool should be run in unlined, plastic, or stainless steel-lined boreholes.
