This project aims to contribute to improving the knowledge of geothermal energy in Spain, a topic of great relevance in the context of energy transition. Geothermal resource exploitation projects require high initial investment, mainly due to drilling costs, which increase considerably with depth. The correct location and evaluation of the distribution of temperatures at depth and their anomalies is a key aspect to minimize risks. 

The consortium formed by professionals from CSIC and GeaPraxis aims to evaluate the geothermal potential of Alto Guadiana, based on the Alpine tectonic model of the Betic Foreland developed by GeaPraxis. 

Existing data on structural geology, lithostratigraphy, petrophysics, hydrogeology, and geophysics will be collected and analyzed. New measurements of hydrogeological and thermal values (surface heat flows and thermal gradient) will be carried out in situ, and samples will be taken to determine their petrophysical parameters (thermal conductivity, radiogenic heat production, porosity, permeability, density) in the laboratory. The analysis and integration of these data will enable the creation of a 3D geological model. Using thermal calculation software, the distribution of temperatures, thermal gradients, and heat transfer of the region will be determined. These results will allow the elaboration of maps of geothermal potential and proposal of recommendations for the use of geothermal resources in the Alto Guadiana. 

Finally, it is intended to create a methodological workflow that serves as an example of application to other areas of Spain and culminates with knowledge of the shallow and deep geothermal potential of the entire territory.
