First injection test of BEACH completed
The injection began on 2 June and lasted for two weeks, during which 240 m³ of cold water were injected. The borehole will remain closed until early August. The test provides valuable data on the hydraulic response of the rock mass to long-term injection.
During the injection, researchers observed a relatively low level of seismic activity compared to previous high-pressure injection tests conducted for geothermal research. Nevertheless, the seismicity cloud offers insights into pressure propagation and the creation of new flow paths through the rock. The injection was accompanied by innovative noble gas tracers, which help track the fate of the water within the fracture network.
After the borehole is reopened at the beginning of August and several weeks of outflow have taken place, the next phase of the experiment will begin. This time, hot water will be injected following the same procedure as during the cold-water injection.
