... is performed utilizing analytical methods to study the effect of the ionic composition and ionic strength on the rock sample wettability. The combination of Thermogravimetric Analysis (TGA) and Fourier Transform Infrared (FTIR) spectroscopy is a time saving experimental approach, suitable for wettability...

... brine in contact with the calcite. There is no single point of zero charge; all dissolved aqueous species are charge determining. Rock-equilibrated aqueous composition controls calcite surface ion-exchange behavior. At high ionic strength, the electrical double layer collapses and is no longer diffuse...
