Electromagnetic casing inspection tool
The EM Pipe Scanner electromagnetic (EM) casing inspection tool uses 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.
The versatile EM Pipe Scanner 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.
The EM Pipe Scanner tool uses three types of noninvasive EM measurements to characterize well casings. These nondestructive induction methods employ both low- and high-frequency induction currents. Metal loss and changes in casing geometry are detected by combining the three measurement types.
Two types of images are produced: a low-frequency-EM thickness image for evaluating the remaining metal and a high-frequency discrimination image produced from 18 pad sensors mounted on the tool centralizer arms.
