I propose to use sessile drop method to experimentally quantify the wettability of kerogen. Experimental wettability on isolated kerogen has not been done previously. The experiments would be performed on kerogen samples covering a range of kerogen types and natural and synthetic kerogen thermal maturity states. The novel aspect of the experimental part of this proposal is to integrate the chemical alterations in kerogen to its wettability characteristics using a suite of pure isolated kerogen. This task will be used to evaluate objective III and verify hypothesis I.
