I am enjoyed to start a new study for the CO2 storage department of TotalEnergies.
I am asked to provide a comprehensive and quantitative model of the coupling between the mechanics and the permeability of clayrocks, as well as indications of the geological conditions resulting in the brittle/permeability increasing behavior of clayrocks, in order to secure CO2 storage operations.
This will serve in the screening of potential CO₂ storage sites and in the estimation of storage capacity in terms of caprock resistance and maintenance of low permeability.
The results will be used to assess leakage risks at currently operated fields.
