    apply the stresses measured in Visund to a single well in order to determine what mud weight should have been used while drilling the well. The analysis and results match precisely with the mud weight used in the wellbore. This well was the most successful well in the Visund field in terms of minimizing lost time during drilling. I also explore the

  • Simulation of rock failure modes in thermal spallation drilling

    Thermal spallation drilling is a contact-less means of borehole excavation that works by exposing a rock surface to a high-temperature jet flame. In this study, we investigate crucial factors for the success of such thermal drilling operations using numerical simulations of the thermomechanical processes leading to rock failure at the borehole surface. To that end, we integrate a model
