Abstract

The aim of this study is to evaluate the mechanical effects of the in-pore crystallization of salts during injection of supercritical carbon dioxide in the context of CCS. Isotropic linear poroelasticity modeling has been used to predict the macroscopic equivalent tensile stress in two cases: a REV linked to an infinite resrevoir of constant concentration, and an isolated REV subjected to an injection of dry supercritical carbon dioxide. Results show that crystallization pressure cannot be neglected while calculating the mechanical behavior of an aquifer during CCS.
