Potentiel géothermique du sous-solGeothermal potential of the subsurface

APIExecutable4/7Query nowOpen workbench Subscribe🇫🇷France

This dataset from the Bordeaux Métropole open data portal maps the geothermal potential of the subsurface across the metropolitan area, structured on a 100m x 100m grid. It provides information on resource availability, ranges of maximum aggregated flow rates by depth interval, and estimated thermal conductivity by depth interval. Published as open data by Bordeaux Métropole, it is accessible without authentication and can support planning and feasibility studies related to geothermal energy exploitation within the metropolitan territory.Dictionnaire Public Ce jeu de données surfaciques, représente à la maille 100m x 100m, le potentiel géothermique du sous-sol de la métropole bordelaise (disponibilité de la ressource, gamme de débits maximum agrégés par plage de profondeur, conductivité thermique estimée par plage de profondeur,...
