Geochemical modelling
Entity:
Development of geochemical (reactive transport) models combining flow processes, solute transport and chemical reactions. The models are applied to the study of gas-water-rock interaction, both at laboratory scale and at field scale (underground storage). They allow a quantitative interpretation of laboratory experiments (changes in chemical and mineralogical compositions) and the evaluation of possible effects at the field level.
Challenges met
- Quantitative interpretation of experimental results in terms of flow properties, transport and reactivity of the different mineral phases.
- Evaluation of possible alterations due to gas-water-rock interaction at field scale.
