Abstract
Torsional, axial and lateral vibrations introduced when a mud motor is used with a drilling tool to drill a borehole are calculated using a model. The model includes different computational modules for each of three distinct motor sections: power, transmission and bearing. The resulting calculated vibration effects are used to enhance the drilling tool and drilling operation.
