CO₂ injection timeline
The life of one injection on your Berea plug: the plume grows while you pump, then migrates up-dip after shut-in while brine re-enters and traps CO₂. Same model as the Berea plume table — measured plug values (porosity 0.221, 914 md, S_gi 0.55, S_gr 0.31; S_gr,max 0.415 from the plug's own Land fit).
Inputs
Starting values are the plug's lab conditions (122 °F, 1,305 psi) plus assumptions, not your data: 1 Mt over 10 yr, 5,000 acres, 100 ft thick, 2° dip, brine 1,050 kg/m³ and 0.5 cp, compressibility 1e-5 per psi. No residual trapping is counted while injection runs — trapping starts when the plume moves after shut-in.

Each year reruns the same trapping and migration model as the charts above (Hesse et al. 2008; MacMinn et al. 2011; Land 1968). Solid circle = still-mobile plume that year (shrinks as brine re-enters; disappears once fully trapped, and the drift stops there); dashed = earlier years; shaded strip = rock the plume has swept, where trapped CO₂ is left behind. Simplified top-down sketch: plume drawn as a circle moving straight up-dip in even rock, not a gridded simulation.
