SaltPower electricity generation can be used to harvest more energy from heat depleted geothermal brines. Thisstudy is an attempt to determine rock–fluid interactions by a synergy between isothermal titration calorimetry(ITC) and core flooding experiments. The results from the ITC experiments show dynamic rock–fluid andfluid–fluid interactions that take place in the reservoir upon brine reinjection. The direct implication of thosedynamic interactions is the stabilization of clay particles loosely attached to the pore surfaces. Formation da-mage is observed when Thisted and diluted Thisted brines are reinjected into Berea sandstone core plugs. Fe(III)oxides precipitation inside the porous media is the main reason for that permeability reduction.
