    Abstract

    Rock became more CO2 wet with increasing pressure, temperature and brine salinities and less CO2 wet with increasing surface roughness - i.e. a lower storage capacity can be inferred for structural trapping. Moreover, we demonstrate that gas densities correlate remarkably well with wettability also a physical model was developed to provide a theoretical framework. Furthermore, the permeability of sandstone samples reduced after injection of brine, CO2-saturated brine or supercritical CO2 at reservoir conditions.

    Curtin would like to pay respect to the Aboriginal and Torres Strait Islander members of our community by acknowledging the traditional owners of the land on which the Perth campus is located, the Whadjuk people of the Nyungar Nation; and on our Kalgoorlie campus, the Wongutha people of the North-Eastern Goldfields.
