Cased-Hole Logging

Magnetic Thickness Tool


Magnetic Thickness Tool

Absolute wall thickness and OD measurements

The Magnetic Thickness Tool (MTT) uses 12 miniature magnetic sensors to investigate variations of pipe metal thickness. The sensors are mounted on collapsible bow springs, allowing the tool to pass through tubing and log pipes up to 7 in. Combining the data with data from the MIT, metal thickness and OD are derived.

 

Key Features

  • Inspection of tubing for external and internal metal loss
  • Measures absolute wall thickness
  • Detects gradual wall loss, casing wear and other damages
  • 3D visualisation available
  • Requires MTT data for internal diameter
  • Combinable with other GE Ultrawire™ tools
  • Memory or surface read-out operation
