After almost two years of intense work to build the stimulation and monitoring boreholes, the drilling campaign has been finished last week by cementing a steel-casing in ST2. By now, nine boreholes with a total length of some 2’500 meters drilled have been completed - an impressive achievement!
For the drilling in Bedretto a completely new drill-rig has been engineered and was transported brand-new on-site in 2020. Now, after successful completion the drill-rig and its equipment were dismantled, moved out of the tunnel and are now being returned to the drilling company's warehouse.
Currently, the new boreholes are being prepared for the instrumentation, which will start in July 2021. 11 June 2021
