"WebOnce CO 2 is injected into a deep saline aquifer, as CO 2 is less dense than the formation fluid, the supercritical CO 2 rises buoyantly as a separated phase through the porous rocks until it reaches the top of the formation, where it meets and is trapped by an impermeable layer of caprock. This is called structural/stratigraphic trapping. " - Co2 injection into saline aquifers
