.... illite) of three different gas densities scenarios (i.e. low (Helium), moderate (Nitrogen), and high (CO 2 ) gas densities). To do so, we measured the advancing and receding contact angle (i.e. wettability) of illite for CO 2 /water, nitrogen/water, and Helium/water systems at a constant (333 K) and four...

... We investigated the utility of a modified Washburn method, combining results of two sorption experiments, to study wettability alteration processes. The main objective in deploying this technique was to avoid the difficulty of direct contact angle measurements in surfactant solutions. In such...
