Eliminating Stickslip

1. Operating Parameters

1.1. Reduce WOB to reduce slip dysfunction for an aggressive Drill Bit

1.2. Reduce RPM to reduce torsional vibrations

1.3. Optimize drilling parameters.

2. Condition of Wellbore + Tortuosity

3. Lubricity of Drilling Fluid

4. Drill Bit Design/Optimization

4.1. Reduce depth of cut- Aggressive cutters (Reducing depth of cut reduces torque variations and excites stick slip)

4.2. Optimize bit design to a less aggressive drill bit. Drill bit to have less blades and less points of contact.

5. Drill String Design/Optimization

5.1. Increase torsional stiffness of Drill string. Soft string prone to store reactive torque and cause torsional vibrations/stick slip

6. Type of formation drilled
