Drilling-Vibrations Modeling and Field Validation

A modeling tool has been developed that enables drilling engineers to design vibration-resistant bottomhole assemblies (BHAs), given tool-placement constraints and desired directional objectives. This model can be applied to configurations with the majority of common drilling components. Modeling results have been validated in large, intermediate, and small hole sizes. Redesign has resulted in improved drilling results, including increased on-bottom drilling time, longer tool life, higher rate of penetration (ROP), reduced nonproductive time associated with tripping, and better hole quality.
