... Abstract This paper presents a study of heterogeneous caprock fracturing processes during underground CO 2 injection into a brine aquifer. We simulate CO 2 injection and fracturing using a combination of theTOUGH2 multiphase flow simulator and the RDCA rock discontinuous cellular automaton...

... of CO 2 is analyzed, and the XFEM is adopted to simulate the injection induced fracturing process of the naturally fractured caprock. Introduction An ever-increasing amount of scientific evidence suggests that anthropogenic release of CO 2 has led to a rise in global temperatures over the past...
