Comportement des roches sous sollicitations thermiques et circulation de fluides (FLUTE)

Abstract : The main objective of FLUTE is to optimize the extraction and storage of natural resources and to minimize the risks for a better knowledge of the host rocks. The specific objective of FLUTE is to deepen the knowledge of the textural variations of type rocks of the Grand Est region in the fields of storage, geothermal energy and hydrocarbons (chalk, sandstone, granite) subjected to thermal stresses. Temperature variations can lead to rock fracturing which will depend on their mineralogy and texture. If this fracturing is added to the circulation of fluids at different temperatures, the textural variations undergone by the rocks modify their transfer properties and thus their functioning. This project is based on an innovative experimental part conducted on a small scale on the processes of deformation, fracturing and dissolution of rocks under conditions similar to those of the storage or geothermal domains. The originality of this project lies in (i) the use of imaging techniques for the study of other materials that have never been used on rocks before, and (ii) the study of textural variations of rocks subjected to fluid flows with contrasting temperatures.
