Electromagnetic (EM) Module
The EM module is battery powered and can operate during all phases of drilling operations, including tripping, drilling and lost circulation. EM measurement is particularly attractive in wells drilled with unconventional drilling fluids such as foam, mist or aerated mud where mud pulse measurement is ineffective. EM tools also require no moving parts.
You can convert your existing mud pulse system to EM by adding the module or purchase a field-ready EM MWD kit.
