The drilling rig on the website of the Haute-Sorne geothermal challenge, Switzerland (supply: Geo-Energie Jura)
Having reached the goal 4000 meters depth, drilling of the primary properly for the Haute-Sorne geothermal challenge in Jura, Switzerland has been accomplished.
Drilling of the primary properly for the Haute-Sorne deliberate geothermal energy challenge within the canton of Jura in Switzerland has formally been accomplished, efficiently reaching the goal depth of 4000 meters in lower than three months. The rig is presently being demobilized whereas knowledge from the drilling operations are present process evaluation.
The following step for the challenge will probably be to conduct varied checks on the borehole, that are anticipated to began by early 2025 and final nearly a yr. The choice on whether or not to proceed with the event of the challenge will rely on the knowledge collected from these checks.
Maybe simply as vital is the truth that the drilling operations had been accomplished with none seismic occasions.
“We’re more than happy to have accomplished this drilling on time and with none geological incidents,” stated Olivier Zingg, Director of Geo-Energie Jura.
Geo-Energie Jura is a public restricted firm with shareholders Geo-Energie Suisse, EBL (Genossenschaft Elektra Baselland), EWB (Energie Wasser Bern) and EWZ (Elektrizitätswerk der Stadt Zürich).
The challenge is a serious milestone for geothermal within the area, as it’s the first properly drilled within the Jura Arc, between Geneva and Basel, that utterly penetrates the sediments and reaches the crystalline basement.
The challenge has needed to contend with unfavourable public notion and vital native opposition throughout its course. Extra measures had been put in place to handle the considerations from the general public, together with the deployment of a predictive seismic monitoring system and the institution of an oversight committee assigned by the Swiss federal authorities.
