In carbon storage activities, and in shale oil and gas extraction (SOGE) with carbon dioxide
(CO2) as stimulation fluid, CO2 comes into contact with shale rock and its pore fluid. As a
reactive fluid, the injected CO2 displays a large potential to modify the shale's chemical,
physical, and mechanical properties, which need to be well studied and documented. The
state of the art on shale–CO2 interactions published in several review articles does not
exhaust all aspects of these interactions, such as changes in the mechanical, petrophysical …
