CO2 Sequestration [Mineral Trapping]
How do we ensure, whether, the resident brine remains, either, chemically under-saturated or super-saturated with reference to its equilibrium condition – both spatially and temporally in an aquifer – leading to mineral precipitation or dissolution – in a CO2-brine system?
Have do we have a control over the evolution of local ‘solubility changes’ - as a function of aquifer pressure and temperature?
When could we expect the dissolution of CO2 - driving the precipitation of brine – as a function of space and time?
In such cases, how do we capture the variations in pore-scale geometry that eventually modifies the least resistive pathways for CO2 flow and brine transport?
Feasible to capture the values of dynamic porosity and permeability – as a function of space and time – during mineral precipitation/dissolution?
In such cases of simultaneous mineral precipitation and dissolution, how do we correlate the relation between porosity and permeability – towards assessing dynamic CO2 storage and transport – in the absence of capturing, the moving CO2-brine interface?
