Examples of Key Findings
Buoyancy Flow Reduces Mobile CO2
Residual Gas Saturation Determines Mobile CO2
Well Completion Can Avoid Seal Integrity Issues
After injection ends, natural processes reduce the amount of mobile CO2
- Dissolution into brine
- Gravity driven flow
- Mineralization
Time required to eliminate mobile CO2 depends on petrophysical properties of aquifer
- Residual gas saturation
- Average permeability
- Relative permeability (especially hysteresis)
- Anisotropy
