Multi-salinity core flooding study in clay-bearing sandstones, a contribution to geothermal reservoir characterisation

Porosity and permeability measurements aid the characterisation of geothermal reservoirs as they improve understanding of the impact of rock-fluid interactions during the life cycle of wells. Core flooding experiments can help us comprehend the rock-brine electrochemical system as critical parameters like salinity, pH, temperature, or pressure change. If the clay mineral content is significant it can reduce permeability and porosity since these particles can block the pore throat network connectivity through clay migration or swelling.
