Seals or caprocks are an essential component of subsurface hydrogeological systems, guiding the migration of hydrocarbons and trapping them over geological time scales. These sealing properties are achieved by the fact these rocks have pore sizes on the order of a few micrometers to a few nanometers which makes their permeability extremely low, on the order of a few nano-Darcy. These rock formations are crucial to current technologies like underground geological carbon sequestration that requires a secure site to store and contain CO2 in a high porosity, high permeability reservoir (e.g....
