Dependence of clay wettability on gas density

Understanding wettability of clay minerals is crucial in assessing primary migration of hydrocarbon and evaluating CO 2 storage capacities and containment security. In spite of recent efforts, there is considerable uncertainty of experimental data and theoretical predictions are lacking. We, therefore, developed new correlations to predict the advancing and receding contact angles of three different clay minerals (i.e., montmorillonite, Illite...
