CO₂ project summary

One site-wide plan from your saved reservoir profile and injection plan, with the plume map model for each well. Edit those pages; this one updates.

Reservoir

No saved reservoir profile — using the injection plan's reservoir. Save a profile.

Injection plan (starting values, not saved)

100,000 t/yr per well for 10 yr, 5,280 ft spacing, target 10 Mt trapped; S_gr,max 0.382.

Wells needed

CO₂ injected

22 Mt

CO₂ trapped

10.32 Mt

Site area

14,080 acres

Peak pressure at a well

463 psi

Added by a neighbor

93 psi

Wells on a square grid at your spacing; circles are each well's plume when injection stops (to scale, before up-dip migration).

One well: plume migration and pressure

Dashed: plume when injection stops. Shaded: mobile CO₂ now. Hatched: swept by returning brine — CO₂ left there is trapped. The plume has moved past its starting outline; brine has re-entered all of it.

Pressure rise above starting reservoir pressure. Solid: at the well. Dashed: 1 mile out. Blue line: the time you picked.

Each well: 1 Mt injected, 0.47 Mt trapped (46.9 %), brine re-entry 100.0 %.
Reservoir temperature 190 °F from depth and your gradient; CO₂ density 631.8 kg/m³ (Span-Wagner 1996).
Trapped share is residual trapping only (Land 1968, S_gr,max 0.382); solubility and mineral trapping are extra.
Pressure is Theis (1935) in brine: 10 yr injection, brine 0.5 cp, compressibility 0.00001 per psi — assumptions, not your data.
Plume diameter (2604 ft) fits inside the 5280 ft spacing.
Neighbor pressure is from one well at the spacing distance; a full grid adds several neighbours, so field pressure is higher than one well alone.
