I propose to test the impact of kerogen wettability at different levels of thermal maturity on the wettability of organic-rich mudrock experimentally using (i) sessile drop test on organic-rich mudrock core samples, (ii) spontaneous imbibition test on crushed mudrock samples, and (iii) floatation technique. This study will be conducted on mudrock samples with different natural and artificial thermal maturity levels of organic matter present in it. This task will be used to evaluate objective IV and verify hypothesis III.
