Advanced 4D Drilling Dynamics Model Simulates Downhole Vibration and Helps to Optimize in Preventing Drill String Failure

APOGCE 2024
Downhole vibration, such as backward or chaotic whirling, is one of the primary causes for drill string failure during drilling operation. Understanding drilling dynamics is crucial for determining the mechanism of vibration and fatigue accumulation so
