The typical geological targets of such projects were hot, and therefore necessarily deep crystalline massifs, which were supposed to be sufficiently tight in order to allow fluid transfers without too much loss of heat bearing fluids between the injection well and the production well, through one or several fractures, artificially maintained open under a sufficiently high pressure in order to allow the expected flow. date: 2010 date_type: published publication: Comptes Rendus Geoscience volume: 342 number: 7-8 publisher: Elsevier pagerange: 493-501 id_number: doi:10.1016/j.crte.2010.03.002 issn: 1631-0713 official_url: http://doi.org/10.1016/j.crte.2010.03.002 access_IS-EPOS: limited owner: Publisher citation: Fritz, Bertrand and Gérard, André (2010) On the way to the exploitation of deep geothermal resources in naturally fractured environments.
