Caliper Log |best| -

Primarily used for casing inspection to detect corrosion, scale buildup, or mechanical deformation in the pipe. Key Applications in Drilling and Geoscience

Often provide a basic diameter measurement, sometimes as part of a density or porosity logging tool. caliper log

The data provided by a caliper log is used across multiple stages of a well's lifecycle: Primarily used for casing inspection to detect corrosion,

Can identify borehole breakouts and elongations, helping engineers understand in-situ stress orientations. The primary purpose of a caliper log is

The primary purpose of a caliper log is to measure the actual size of a borehole, which often deviates from the size of the drill bit. This is achieved using mechanical arms—typically 1, 2, 4, or up to 40 or 60 fingers in specialized casing inspection tools—that press against the borehole wall as the tool is pulled to the surface.

A is a continuous record of the diameter and shape of a borehole as a function of depth. It is one of the most fundamental measurements in borehole geophysics and petrophysics, serving as a critical indicator of borehole stability, lithology, and the quality of other logging data.
