How-Drillstring-Rotation-Affects-Critical-Buckling-Load PDF 1

Buckling of tubulars inside wellbores has been the subject of many researches and articles in the past. However, these conservative<br>theories have always followed the same assumptions : the wellbore has a perfect and unrealistic geometry (vertical, horizontal, deviated,<br>curved), the friction and rotation effects are ignored, conditions relatively far from actual field conditions. How do tubulars buckle in actual<br>field conditions, that is, in a naturally tortuous wellbore with friction and rotation? Can we apply theories developed for perfect well<br>conditions (no tortuosity, no friction, no rotat
