Multifinger calipers (24, 40 & 60 fingers)

READ’s range of 24, 40 and 60-finger calipers provide highly accurate measurements of the profile of the internal well-bore geometry and barrier condition.

The 24-sensor caliper is used to log the internal surface of smaller sized tubing or casing, most commonly used in slim hole completions or where reduced ID restrictions are present. The 40-sensor caliper is used to log the internal surface of tubing or casing, while the 60-sensor caliper is used to log the internal surface of larger sizes of casing.

The tools include an inclinometer to ensure an enhanced 3D image of the well bore is produced.
