Electromagnetic Thickness Tool (EMT-S)
Description
The Electro-magnetic Thickness Tool-Scanning (EMT-S ) is designed to detect the damage of tubular by calculating the remaining wall thickness and corrosion extent. By measuring the phase shift of an induced electromagnetic field, it can accurately indicate the column structure and location of other objects in concentric pipe. High resolution and fast sampling enable EMT-S to scan tubular geometry to provide position allocation of non conformities.
- Measures the remaining wall thickness of concentric casing in one run.
- Determination of the type(s) of damage: pits, penetrations, cracks in transverse or longitudinal plane.
- Determination of inner casing penetration.
- Locating inner and outer collars in concentric casing.
- Well bore temperature logging.
Application
- Compact Design
- Ability to adjust decay time window during logging to capture the response of outer casings.
- High resolution.
- Through-tubing screening.
- Stainless steel scanning.
- Well completion monitoring: Corrosion progress and repeatability.

The EMT-S tool uses an induced electromagnetic field to measure the phase shift which allows the tool to determine the remaining wall thickness of the tubular.
The EMT-S tool can detect various types of wellbore damages, including pits, penetrations, and cracks in the transverse or longitudinal plane of the tubular.
Yes, The EMT-S tool can be deployed in most well situations to acquire necessary well data for Wellbore tubular and concentric casing.
Yes, the EMT-S tool can be used for casing ID/OD damage evaluation, leak locating, and cement bond evaluation using some of our other tools (like the MFC, DSNT, and RBT) to provide better decision-making results.
