Copyright 2019 ARMA, American Rock Mechanics Association. A review paper is presented on the stability analysis of rock formations for carbon sequestration by summarizing the potential loadings that caprock can be exposed to. An overview of the existing coupled analytical models of rock, Thermo-Hydro-Mechanical (THM) models, describing mechanical changes, flow effects and thermal distributions due to different loading conditions on porous rock is given. Additionally, experimental work based on the theoretical differential equations of THM models is outlined, as well as different numerical studies based on constitutive models. Generally, numerical modeling techniques used in the literature were mainly set up for the update and validation of the undertaken experimental work, which was compared to the modeling results.
