Abstract
Summary
Concerning injection of CO2 into saline aquifers, it may induce formation of dry-out and precipitation of salt near the injection well, which may reduce formation porosity, permeability, and injectivity.
Here, we investigate experimentally the possibility that chlorine isotopes could be used as a geochemical tool to constrain the interplay of solute transport processes occuring during CO2 injection. δ37Cl is already used as a tracer of solute transport (especially diffusion) and salt precipitation so that it is likely to be useful to characterise their complex dynamics in porous media during evaporation.
