The Electromagnetic Thickness Tool (EMT24) has been designed to measure casing wall thickness. The power is supplied and the signals are transmitted through mono-conductor cable.

 

The EMT includes an array of miniature sensors. Each sensor obtains one magnetic variation signal. All of the data from the twelve sensors are transmitted through the telemetry cartridge to the surface to be presented in log records.

 

The EMT must be centralized during operation, and combined use with the multi-finger caliper is recommended. Special  interpretation software is provided for interpretation of EMT data only or for combined interpretation of EMT and multifinger caliper measurements. Three-dimensional imaging and outout may be realized.
