Multi-Finger Caliper
|
Product Overview
|
The Multi-Finger Caliper (MFC) has 24 to 56 high resolution calipers which measures the internal radii of
the wellbore tubing and casing. Accurate measurements can be made in tubular sizes from 1.75 inches to 13.8
inches in diameter (with extended fingers kit). The MFC uses a series of “contactless” displacement sensors
and a corresponding number of measurement fingers. When moving along the inner casing wall, the radial
displacement will be changed into an axial displacement of the sensor, which is then processed, coded, and
transferred to surface system where the image of the casing will be obtained.
The MFC can be used to detect casing deformation, bending, fractures, holes, scale deposition, paraffin
build-up, and inner wall corrosion with high accuracy.
