Vibration Monitoring Module

The Vibration Monitoring tool (VIBMON) monitors downhole shock and vibration in three axes.

Real-time telemetry and display of downhole shock and vibration enables drillers to avoid costly downhole equipment failure and optimize ROP. Data is also recorded downhole for plotting and analysis on surface.


  • Real time monitoring of axial and lateral shock allows the user to proactively identify tool damaging situations and take immediate action
  • Downhole recording of shock and vibration allows for detailed plotting and analysis on surface
  • xxMemIO and vmAnalyzer applications for easy downloading and analysis of VIBMON data
  • Real-time VIBMON data display on xxSAPC or xxDRT screens
  • vmIndicator provides for display of real-time shock and vibration for users not running the XXT xxMWD/PCTM Program Suite
