Type I kerogen has high H/C ratio and low O/C ratio. The hydrogen to carbon ratio decreases from type I to type III. The aromaticity is also variable between different types of kerogen, with type III being low in aliphatic compounds and high in aromatic compounds. The variations in molecular structure and components among different types of kerogen affect their surface properties such as wettability. I propose to quantify these impacts using molecular simulation method. The effect kerogen type on its wettability has not been quantified in the past. This task will be used to evaluate objective I and verify hypothesis I.
