.... Water adsorption isotherms have also been quantified on shale samples ( Ma et al. 2020 ; Dang et al. 2021 ); however, the objective of these publications was not to demonstrate the correlation between wettability and water adsorption. For instance, Ma et al. (2020) computed water vapor adsorption...

... Abstract Experimental methods are commonly used to determine the ability of a rock to adsorb gas by means of isothermal adsorption experiments. Adsorption isotherms quantitatively describe the relationship between the amount of gas adsorbed onto a rock surface and associated equilibrium...

We apply the model on several shale samples and compare the results with the PSDs obtained from BET (Brunauer-Emmett-Teller) analysis using the N 2 and CO 2 adsorption isotherms. The proposed model describes...
