Drillstring Vibration Monitoring
Drillstring vibration is a major contributor to downhole tool failure. It may also cause hole damage and increase the need for more frequent rig repair. Timely detection and mitigation of downhole vibration is key to avoiding nonproductive time (NPT) and preventing equipment damage. With full knowledge of downhole dynamics conditions, effective changes can be made to the drilling parameters of weight-on-bit, rotary speed and flow rate to mitigate harmful vibration.
