Caractérisation géomécanique de la dégradation des roches sous l'effet de l'injection de gaz acides

Abstract : This work composed of both experimental and theoretical studies aims at the characterization of carbonate rocks geomechanical evolution during CO2 injection. The first part of the study deals with the experimental work in order to characterize the petrophysical and geomechanical evolution of carbonate rock under chemical effect. Microstructure evolution has been investigated, in order to provider a better understanding of the observed phenomena at the macroscopic scale. The aim of the second part is to derive macroscopic properties of carbonate rock in framework of a micromechanical approach. The elastic moduli and effective strength in both intact and altered states have been computed and are compared with experimental data
