Simulation of Mid-String Stick-Slip and Mitigation Using Multibody Dynamics

Stick-slip has long been recognized as a major source of drilling problems including excessive vibration, excessive bit wear, shortened bit runs, and BHA or drillstring failures that can lead to higher drilling costs.  In this presentation, we present a novel workflow for simulating mid-string stick-slip in realistic horizontal wellbore geometries and for testing mitigation methods using multibody dynamics modeling.
