The project ZoDrEx, funded by EU initiative Geothermica – Era Net, aims at demonstrating drilling, completion and production methods to increase the technical and economical chances of success in geothermal energy applications. At the Bedretto Lab, the project will focus on the performance of zonal isolation technologies and their potential importance during stimulations as well as on the fluid driven percussion drilling method in highly deviated trajectory boreholes to enhance drilling efficiency in crystalline rock.
The figure shows the experimental setup for the first experiment series at the Bedretto Lab combining the projects VALTER, DESTRESS and ZoDrEx in one experiment. The fracture and faults extrapolated from the tunnel are shown in map view for comparison.
