Inauguration of Bedretto Lab
The new rock laboratory "Bedretto Underground Laboratory for Geoenergies" (Bedretto Lab) was inaugurated on 18 May 2018 in Bedretto, Switzerland. More than 200 vistors seized the opportunity to visit the lab and learn more about geothermal research.
The DESTRESS project in Bedretto aims to demonstrate that the construction of a heat exchanger that is sustainable over several decades can be planned and controlled with the aid of hydraulic stimulation processes. The experiments will be carried out on scales of several hundreds of meters. The larger scale implicates longer boreholes, which allow more realistic experiments to be carried out, applying different stimulation concepts.
Similar to other projects, this project will perform in-situ stimulation concepts tests while monitoring hydro-seismo-mechanical key parameters at a high spatial resolution. The addressed questions are:
- Which stimulation concepts are appropriate for enhancing the permeability by orders of magnitudes while minimizing induced seismicity?
- What are the relationships between the hydro-mechanical response, the stimulation concept, permeability creation, effective porosity, and induced seismicity?
- How can micro-seismicity be minimized?
- What are the heat exchanger properties of the reservoir?
