Multifinger Imaging Tools


Multifinger Imaging Tools

For logging in tubing and most casing sizes

MIT60 is used in large casings for maximum measurement coverage. The MIT60 reaches to14 inches internal diameter. MIT40 is the most commonly used tool. Best coverage in most tubings. MIT24 is used in small tubings/casings or where restrictions make MIT40/60 unusable.

The Multifinger Imaging Tool (MIT) measures the inner diameter of a wellbore, and is able to detect very small changes of the internal surface conditions with a high degree of accuracy. The tool has an array of hard surfaced fingers, each finger makes contact with the inside wall of a pipe measuring radius with precise resolution and accuracy. The tool is available in three different sizes; 24, 40 or 60 fingers. All tools may be run with extended fingers to increase the measurement range.
