CO₂ reservoir plume run
Type your reservoir's own depth, thickness, permeability and pressure — the full plume migration, residual trapping and pressure buildup run from those, not the trapping calculator's starting values. Temperature comes from your depth and gradient; CO₂ density and viscosity are calculated at the resulting temperature and your typed pressure (Span-Wagner 1996; Fenghour 1998).
Your reservoir
Starting values are assumptions, not your data: 8,000 ft, 100 ft, 50 md, 0.15 porosity, 3,500 psi, 1.5 °F/100 ft from 70 °F, 1 Mt, 100 yr, 5,000 acres, 2° dip, S_wr 0.3. S_gr,max 0.382 is the Land fit to your five core plugs. k_rg* 0.4 and brine 1,050 kg/m³ stay at the calculator's values. Saved to your account when signed in; otherwise in this browser only.
