Residual gas trapping occurs when a small amount of CO2 becomes disconnected or ‘snaps off’ from the CO2 plume as the CO2 moves through the porous rock. The CO2 is stored in the pores in tiny bubbles, trapped by surface tension. The CO2 can’t move out of the pore space and remains fixed underground.
