EM Pipe Scanner

Electromagnetic casing inspection

EM Pipe Scanner electromagnetic casing inspection tool combines a slim mandrel with 18 pad sensors to quantitatively scan the interior surface and thickness of production casing. The slim mandrel enables measuring casing corrosion and identifying grooves and splits without having to first pull the completion tubing, saving significant time and cost.

As it descends in the well, the EM Pipe Scanner tool conducts a high-speed reconnaissance run to flag places of interest for subsequent diagnostic scans as the tool ascends. The diagnostic images identify the exact severity and nature of the corrosion. The versatile tool is fluid insensitive, operating in liquid or gas environments, and can be deployed by wireline, tractor, or coiled tubing at up to 90° well deviation. Time-lapse deployment provides corrosion rate estimates, identifies casing corrosion behind tubing, and determines the inner tubular radius behind scale.
