RISVibration Analysis of a Drillstring in Vibration Assisted Rotary Drilling: Finite Element Modeling With Analytical Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Introducing sources of axial vibration into an oilwell drillstring has the potential to improve the drilling efficiency. Vibration generator tools, such as drillstring agitators, are under development or in current use to ...
