The project deals with development, simulation and optimization of dynamic models that can accurately predict the motion of a drill string during a drilling operation. The main focus is on models that are fast enough to be used with real-time data. Extending such models to include the hydraulics of drilling fluids also allows for the estimation of the bottom hole pressure changes. The expected outcome of the project includes partially validated models that can be used to estimate axial and torsional drill string vibrations and are also suitable for real-time implementations.
