Join us for on 25 April 2025 for a webinar on a transdisciplinary approach for geothermal exploration in basement-hosted crustal fault zones.
As part of the regular Focus on Geothermal Webinar series – a partnership of Enerchange and ThinkGeoEnergy, we are proud to host Agatha Hantraye and Nicolas Dall’asta of TLS Geothermics for a webinar on a “Transdisciplinary approach as an innovative tool for geothermal exploration in basement-hosted crustal fault zones (Saxony, Germany).”

Speaker: Agathe Hantraye, Geophysical Engineer, and Nicolas Dall’Asta, Exploration Geologist, TLS Geothermics
Traditional surveys such as active seismic are not the most efficient way of exploring Basement crustal fault zones (B-CFZ) geothermal plays, such as in the Erzgebirge massif in south-eastern Germany (Saxony). To explore geothermal potential of this area TLS Geothermics has acquired a new lease in western Saxony for geothermal exploration (OstVogtland Warme project).
TLS Geothermics has developed, inside its systemic exploration workflow, a dedicated geophysical process in order to quantify B-CFZ geothermal potential. This workflow is based on the joint inversion of gravity, passive seismic and magnetotelluric data (3 passive methods). Each method provides complementary information on density, resistivity and seismic velocity models in the crust. Combined, these methods can help to quantify pressure, temperature, lithology (mineralogy and porosity) as well as fluid composition, with the ultimate goal of efficiently quantifying the geothermal potential and target the first exploration wells.
Agathe Hantraye has an Engineering Degree and a Master’s degree in Geophysics from the School and Observatory of Earth Sciences (EOST) in Strasbourg, France. Following a stint as an intern student in TLS Geothermics, she is now working as a Geophysical Engineer and is responsible for seismic survey design, preparation data acquisition missions, and data analysis.
Nicolas Dall’asta has a Master’s Degree n Geology and Earth Dynamic from the University of Strasbourg and a PhD in Earth Science from the University of Pau and Pays de l’Adours. He is currently an Exploration Geologist for TLS Geothermics and is responsible for geothermal projects in Martinique and Germany.
