Thermo2Pro: A tool to help professionals of the geothermal sector for exploration in deep basin context in France - Development, update, and perspectives
Résumé
The understanding of geology and petrophysical properties is necessary to develop deep geothermal projects. However, this knowledge must be shared within the French professional geothermal community to make the exploration process more efficient. Thermo2Pro is designed to fill the gap between the information derived from R&D projects and the authorities dealing with the deep geothermal exploration in basin context. Contracting authorities, local authorities, and design offices have been gathered in a user committee involved in the development of the project since its inception. The main vector for Thermo2Pro is a Web application where the user accesses the information by simulating vertical or horizontal sections, or boreholes. The information is stored in 3D regular grids derived from scientific projects. The functionalities of Thermo2Pro have been demonstrated through information related to the Trias aquifer of the Paris basin. In that area, the available parameters were mainly a model of geometry, an estimation of porosity, and a model of temperature. The Thermo2Pro project was dedicated to the development of the Web tool and its demonstration. The list of parameters available in Thermo2Pro is being expanded through the TRANS-CLAS project, by adding new information from the Paris basin and other areas such as Alsace and the French Massif Central. In addition, the use of data of the Dogger reservoir in the Paris basin is under study. Thermo2Pro and TRANS-CLAS are co-financed by the ADEME (French Environment and Energy Management Agency) and BRGM (French Geological Survey). The parameters used in Thermo2Pro have been acquired and inferred in the scope of the CLASTIQ-2 project co-financed by the ADEME and BRGM.
