Drillstring integrity focuses on:
- prevention of mechanical overload
- protection from fatigue
- minimizing excessive shock and vibration
Specialized software is used to model every bottom hole assembly (BHA) and drillstring. Downhole and surface vibration detection sensors allow the ADT service specialist to measure harmful vibration modes and identify active vibration mechanisms. Correlation with formation evaluation data and surface drilling parameters enables to take the correct actions to reduce damaging vibration and improve performance. Root cause analysis and effective documentation of experience and lessons learned help ensure continued improvement in BHA design, bit and drive selections.
