Short summary
A multi-salinity experiment was conducted in three tight clay-bearing (kaolinite, chlorite, and glauconite) sandstones to study the impact of clay on their petrophysical properties. Chlorite sandstone presented higher electrochemical interaction, followed by glauconite and kaolinite. In the geothermal context, this investigation highlights the importance of ensuring that the correct fluid chemistry is used in clay-bearing geothermal reservoirs.
