Overview

The Electromagnetic Tool (EMT07) measures the remaining wall thickness through single layer or multi-layer casing. It utilizes electromagnetic eddy attenuation to effectively measure the damage condition of downhole pipe string and it is H2S resistant. Tool string: this tool is typically combined with the multi-finger caliper in application.

Application

  • Applicable well conditions: cased hole with any well fluid condition
  • Compatible with WSTbus tools

Features

  • High transmission speed; measure single or multi-layer string; stable operation under high temperature
  • Compatible with WS3000 transmission system

Benefits

  • Can be adapted to WS3000 surface system after software update. No need for customers to buy a new data acquisition system
  • Continuous measurement for improved logging efficiency
  • Extensive application; direct measuring of string damage for multi-layer string without pulling out tubing; can be combined with multi-finger caliper tools.
