CO₂ Injection Well Sizing
Bottomhole pressure required for injection, margin to fracture, and injectivity for a CO₂ storage well in saline aquifer or depleted reservoir. Radial Darcy flow + Hubbert-Willis fracture criterion. Per ISO 27914 / DOE NETL Best Practices.
⚠ Preliminary screening only. Radial Darcy + Hubbert-Willis fracture is an analytical bound; real injection performance depends on reservoir heterogeneity, multiphase relative permeability, geomechanics, and CO₂-brine-rock chemistry. Final injection-well design requires site-specific reservoir simulation (e.g., CMG-GEM, ECLIPSE-CO₂STORE), step-rate injection testing, and Class VI permit evaluation per 40 CFR 146 Subpart H. Verify all results with a licensed reservoir engineer / geomechanics specialist before any field implementation.
