ORCHYD
Novel Drilling Technology Combining Hydro-Jet and Percussion for ROP Improvement in Deep Geothermal Drilling
The ORCHYD project aims to increase the unit drilling rate (measured in rate of penetration, ROP) by four times the average rate currently possible – drastically reducing the drilling costs by up to 65%. This first-of-its-kind drilling approach, combining two established rock cutting technologies – High Pressure Water Jet (HPWJ) for rock cutting (up to 250 MPa) and percussive drilling using down- the-hole (DTH) hammer – will make the utilization of geothermal energy cheaper and more widely available, facilitating the energy transition to tackle the global climate crisis.
