A seismic survey is about to begin on the south of Luxembourg to guage the viability of geothermal heating for the communes of Dudelange and Schifflange.
Seismic surveys are set to start to discover the geothermal potential within the southern area of Luxembourg, significantly within the communes of Dudelange and Schifflange, extending to the town of Esch-sur-Alzette. The surveys will start on the fifteenth of November and are anticipated to proceed till the primary week of December.
Round 2000 geophones can be arrange throughout the survey space to seize seismic information. Waves can be emitted by particular vibro-trucks that may ply a set route between the three key areas talked about prior.
Robert Colbach from the Service géologique de l’Etat explains that the objective of the measurements can be to assist establish the presence and placement of the deepest water-permeable layer within the subsurface which may be thought-about a viable reservoir of geothermal fluids. The geologists already suspect that such layer could be discovered between Esch and Dudelange.
Primarily based on earlier research, temperatures of round 50 °C are anticipated at a depth of 800 meters within the area. However in case you discover the layer at a depth of two,000 meters, issues get actually fascinating,” stated Colbach. At a thermal gradient of three °C per 100 meters, temperatures at that depth can attain round 80 °C.
The specialists have already got a transparent use for geothermal warmth in thoughts – geothermal heating could be provided to the brand new constructing districts of Nei Schmelz in Dudelange and Metze Schmelz in Schifflange.
If the outcomes of the research are optimistic, the challenge could proceed to the exploratory drilling section. If all of the wanted circumstances are met, then at the least two geothermal wells can be drilled at every of the 2 improvement areas.
The Ministry of Power of Luxembourg had already beforehand expressed curiosity in exploring for medium-depth geothermal in south Luxembourg, particularly in Dudelange.
