Multi Finger Calipers

Multifinger calipers provide high-resolution measurements of the internal surface of tubing and casing used to evaluate well performance or well integrity.

Spring-loaded caliper arms make contact with the inner surface of the wellbore and move independently to track any variation in downhole geometry.

The radial position of each arm and its relative orientation in the well are digitized and recorded in order to create a complete 360° map of the wellbore profile that is sent to surface for playback or analysis.
