Aerodynamic stability of bridges
… can then be used to determine the lift force and overturning moment on any bridge section without large scale model tests. Also, the slope of the lift and torque curves obtained in these tests determine the aerodynamic stability or instability of the bridge section. Our problem was to …

Stuck pipe prediction in deviated wellbores: a numerical and statistical analysis.
Due to the significant non-productive times and recovery costs associated with stuck pipe events in oil and gas drilling operations, there is value in being able to predict an impending stuck pipe event. To achieve this, the use of numerical cuttings transport (hole cleaning) models and statistical …

Extending the reach of drilling: better wellbore trajectory and torque & drag models
… or to expose reservoir sections for production and reservoir management advantages, requires accurate planning to reduce the borehole friction and ensure reaching desired targets within defined accuracy. This dissertation aims to extend the horizontal section and push the drilling capabilities …
