Using semi-analytic solutions to approximate the area of potential impact for carbon dioxide injection

► CO2 plume and critical pressure are needed to determine an area of potential impact (AoPI). ► Critical pressure depends on depth and salinity difference between formations. ► Leakage through the cap rock has a strong impact on the size of the AoPI. ► The size of the AoPI is determined by CO2 plume in about half of the cases.
