CO₂ EOR screening is dominated by two questions: can we achieve miscibility at reservoir pressure, and can we get enough CO₂ to the field at acceptable cost? Both belong in the screen from day one.
Reservoir-side checklist
- Depth and pressure sufficient to exceed MMP at planned injection.
- Oil composition — intermediate hydrocarbons favor lower MMP.
- Temperature, reservoir heterogeneity, and gravity-override risk.
- Existing wells and completions capable of CO₂ service.
Surface-side checklist
- CO₂ source: natural, industrial capture, CCUS supply contract.
- Pipeline distance and pressure spec.
- Recycle compression and dehydration capex.
- HSE plan for high-pressure CO₂.
Treat the surface chain as a first-class screen, not an afterthought — and reach for the EOR screening software to rank CO₂ against polymer, thermal and waterflood optimization in the same evaluation.
