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 …

This paper presents a numerical investigation into the effects of pre-induced cracks on
polycrystalline diamond compact (PDC) rock drilling processes under varying pressure …

This paper studies the effects of plasma-induced cracks on rock cutting to support the
concept of a plasma-integrated drag bit for accelerated geothermal drilling through hard …

A reasonable estimation of the geothermal potential of any geothermal system depends on
the reliable knowledge of its geological, geophysical and geochemical parameters. The heat …

The main costs of developing geothermal processes are concentrated in the project of
drilling, accounting for more than 70% of the total budget. Inspired by thermal stimulation …

Deep earth drilling is a key technique to extract oil, gas, and geothermal heat from the earth.
Energy focusing methods have been explored as an alternative approach to reach these …
