About the project
Safe and secure Carbon Capture and Storage (CCS) relies on a good knowledge of mechanisms and processes active during subsurface CO2 injection. Nowadays, the goal is to scale-up CCS projects to gigatons (billion tons) of injected CO2 per year. It is, therefore, paramount to thoroughly investigate coupled reactive THMC processes at different length-scales, time-scales, and operational conditions. In the SaltPreCO2 project, we aim to get better knowledge about CO2 injectivity and containment.
Objectives
We pursue the following research directions to elucidate and predict reactive geo-processes:
- Develop state-of-the-art microfluidic systems coupled with Raman spectroscopy to determine real-time thermodynamic properties of the CO2-brine system
- Delineate the underlying physics, dynamics, and influencing factors on CO2-induced solid and salt precipitation in porous and fractured media
- Investigate the impact of reactive reservoir fluids on mineral precipitation-dissolution dynamics and the consequences for geomechanical properties
