Physical properties of a thermally cracked andesite and fluid-injection induced rupture at laboratory scale

Abstract : The physical properties and mechanical behavior of andesite are of interest in the context of geothermal reservoir, CO2 sequestration and for several natural processes. The effects of thermal crack damage on the physical properties and rupture processes of andesite were investigated under triaxial deformation at room temperature. Secondly we did research on the effect of alteration on physical behavior and mineralogy. At last a series of experiments were performed in order to investigate the effect of fluid pressure variation i) on the mechanical behavior of andesite samples and ii) on acoustic emissions activities
