Magnetic Thickness Detector (MTD) Tool
A corrosion measuring tool primarily run through tubing with the unique ability to simultaneously inspect the tubing and the casing behind it (AER Directive 051). This allows for the integrity of the casing string to be evaluated with neither the requirement for a costly workover rig or the time-consuming removal of the tubing string.
Multi-Finger Caliper (MFC) Tool
Provides direct, accurate, and reliable measurements of internal casing diameters. Used in both drilling & production environments. Applications include – evaluation of corrosion, erosion, wear, bending, buckling, pits, holes, and other defects with high accuracy. It can also be used to measure build-up of scale, paraffin, and other mineral deposits in the wellbore. Both the MTD and MFC tool can be ran together to offer a complete internal and external evaluation of the casing string.
