APS’s SureShot™ MWD Vibration Memory Module (VMM™) is a software-enabled extension to our SureShot MWD tool that measures, analyzes, records and enables real-time transmission of axial (bit bounce), lateral and torsional (stick-slip, chatter and whirl) vibrations and shocks. VMM allows users to assess the severity of downhole drilling to improve drilling efficiency and alert them to vibration conditions that could damage MWD and other downhole tools.
The real-time and memory data can be correlated to drilling events and equipment performance to improve drilling efficiency or prevent failures. The real-time and memory data can also provide evidence for use in warranty claim resolution. Real-time, memory and surface sensor data can be viewed with the SureShot VMM Viewer, plotted with APSPlot™ and exported in industry-standard formats (WITS and LAS).
