Abstract

•We investigated the effect of CO2 rich-brine flowing through Heletz sandstone samples at in situ conditions.•The role of flow rate injections and S content in the injected brines on the chemical processes is evaluated.•Increase in permeability always occurred even if the porosity is decreasing due to gypsum precipitation.•We highlighted the role of local micro-environments on the dissolution/precipitation reactions controlled by diffusion process.
