CO₂ storage site
Enter your site's storage layer and seal. The run uses the same plume, trapping and pressure model as the plume map, plus a seal check. Saved to your account when signed in; otherwise in this browser only.
Storage layer
Mid-depth works out to 160.8 °F and 2,620 psi. Picking a rock type fills typical porosity/permeability — starting values, not measurements; type your own.
Seal (caprock)
The 100 psi entry pressure and 100 ft column are my starting values, not your data — use a mercury-injection or CO₂ breakthrough test on your caprock.
Injection and trapping
The plug supplies only its initial and residual CO₂ saturations (Land 1968 fit); rock and conditions come from your site.
Seal check: column held
Buoyancy of a 100 ft CO₂ column (601 kg/m³ against 1,050 kg/m³ brine) is 19.4 psi vs 100 psi entry pressure (80.6 psi margin). This seal holds up to about 514 ft of CO₂ column. Peak injection pressure rise (247 psi) also exceeds the entry pressure near the well.
Plume radius 1,303 ft, moved 5,159 ft up-dip at 2°.
Model: Land (1968) residual trapping, Hesse et al. (2008)/MacMinn et al. (2011) up-dip migration, Span–Wagner CO₂ density, Theis (1935) pressure in an infinite single-phase brine reservoir.
Seal: buoyancy vs capillary entry pressure (Watts 1987). No faults, fractures, seal geomechanics or diffusion; seal thickness and permeability are recorded but do not change the capillary check.
My starting values: 10-year injection, brine 1,050 kg/m³, k_rg* 0.4, brine viscosity 0.5 cp, compressibility 1e-5 1/psi.
