In the ThermoDrill project, an interdisciplinary team of research institutions and industrial partners from across Europe have joined forces to innovate deep geothermal drilling by combining proven and cost-effective technologies into a completely new process. The unique feature of the new concept is that penetration is achieved by high pressure fluid jet which supports conventional rotary drilling by breaking the stress in front of the bit to increase bit performance. This combination of fluid jetting and rotary drilling is expected to at least double the rate of penetration.
A key point of the concept is to ensure that the technologies and fluids used as well as the drilling process as a whole undergo a systematic redesign and will still be in strict compliance with the most stringent HSE (health, safety and environmental) standards.
