Methods and systems for mitigating drilling vibrations |
| abstract |
Methods and systems of reducing drilling vibrations include generation a vibration performance index using at least one frequency-domain model having a velocity-dependent friction relationship. The vibration performance index may be used to aid in the design or manufacture of a drill tool assembly. Additionally or alternatively, the vibration performance index may inform drilling operations to reduce vibrations. |
