What About My Rig?

Room for Improvement

• Gather data

• Overview

• Look for specifics

• Solve for the easiest

• Test the solution

• Keep learning

Vibration Event and Solution

17

Increase energy available

to the drillstring

Conclusion

Why was ROP

so poor?

Poor bit selection?

High Coupled Vibration is driver

for ROP loss

Formation effect for Lateral

Vibration

Torsional Vibration coupled to Lat

Vibration

WOB dependency evident

Surface paramaters must vary

per vibration zone
