The multi-sensor caliper (MSC™) sensor provides accurate internal casing profiles by using independent measurements of feeler arms. Real-time monitoring of tool response and multipoint calibration allow anomalies to be identified and repeated, increasing accuracy and saving valuable rig time. The tool is available in 40- and 60-arm models. TotalView™ visualization software developed for the MSC provides flexibility for isolating specific features of data and analysis results.

The casing evaluation survey (CES) sensor uses remote field-eddy current detector coils to measure defects in casing, even near large metal masses such as casing collars. The CES sensor is equally sensitive to both inner and outer casing collar corrosion and can confirm wall penetrations. High-sensitivity pads provide increased standoff tolerance and reduce the need for scraper runs.
