"We can only gain the full picture when the results of smaller-scale localized features (reservoir, caprock, wellbore) are merged and upscaled to the context of the whole storage site"
Long-term CO2 storage behaviour: integration of study results and adaptation to regional scale
Participants: BRGM, BGS, GEOGREEN, IFPEN, IGG-CNR, PHIMECA, TNO
This work package aims at evaluating the long-term fate of geologically stored CO2 at the storage complex scale using a set of modelling scenarios similar to the geological context of true demonstration sites. All the work performed in this work package will benefit from a large support of the outcomes provided by the WP3, 4 and 5 for the elaboration of the model scenarios, the geological, geochemical and thermodynamical context and properties of the studied area and new insights on the studied physical processes. In addition, uncertainty assessment conducted in WP6 will constrain the variability of the provided results.
This study includes:
- the influence of the pressure pulse induced by the CO2 injection in saline aquifers on brine displacement;
- the upscaling of trapping mechanisms of CO2 stored in saline aquifers;
- the long-term sealing integrity of fractured caprock and faulted system;
- the impact of CO2 leakage through wells from saline aquifers to overlying groundwaters;
- Task 2.1 Hydro-regional flow modelling of ground water displacement
- Task 2.2 – Multi-scale modelling of the long-term CO2 trapping
- Task 2.3 – Assessment of sealing integrity of fractured caprock and faulted systems
- Task 2.4 - Large scale assessment of leakages through wells
- Task 2.5 - Uncertainties propagation from small to large scale
