Caliper Logging

Profile the internal surface of tubing or casing

Caliper Logging


The Multi Finger Caliper is used to profile the internal surface of tubing or casing to a high degree of accuracy providing identification and quantification of corrosion, wall penetration, deposits and other mechanical damage or features.

It operates either on surface read out or memory mode being capable of deployment on Slick-E-Line®, slickline and coiled tubing. It is available in a range of diameters to suit varying casing/tubing sizes. The number of fingers on a tool increases with its diameter to maintain maximum surface coverage and data resolution. The tools can be run in combination with other Paradigm Intervention cased hole instruments and production logging tools, offering excellent operational flexibility and increased operational efficiencies

Features:

  • Available in 24, 40 or 60 finger versions
  • Surface readout or memory options
  • Combinable with other Paradigm Intervention Technologies tools
  • 3D data analysis
  • Statistical analysis
  • Suitable for all well deviations
  • Tungsten Carbide Tipped Fingers
  • Fast Sample Rate
  • Dual Accelerometer provides accurate deviation and rotational measurement

Applications:

  • Tubing / casing bend - Drift / length ratio calculation
  • Deformation of tubing
  • Helical buckling
  • Tubing collapse
  • Jewellery condition/location
  • Full Wall Penetration
  • Scale deposition
  • Erosion / corrosion identification
