Short description of my research project

Investigation of application possibilities of hydrothermal spallation drilling for deep geothermal heat mining

Spallation Drilling is based on the effect of hard-polycrystalline rocks disintegrating into small disc-like fragments, if rapidly heated up by a heat source. This drilling technology has the potential to significantly reduce the drilling costs for geothermal or oil and gas applications.

The aim of this project is to investigated the application possibilities of spallation drilling under hydrothermal conditions. Therefore, fundamental investigations of the spallation process itself and the required operating conditions will be done. With the required operating conditions known, drilling bits (thermal and thermal-assisted) will be developed and tested in an high-pressure facility. Additionally, models will be developed, which are capable to predict the required operating conditions for specific rock types and the rate of penetration in realistic downhole conditions.
