The wettability of kerogen significantly impacts the overall wettability characteristics of organicrich mudrocks. Kerogen, as the dominant organic component in these rocks, plays a vital role in determining their wettability behavior . The interaction between kerogen and the surrounding matrix influences the wetting properties of the entire system (Chen et al., 2019; Zhao et al., 2021). The presence of kerogen within organic-rich mudrocks introduces complexities in the wettability behavior of these rocks. Kerogen can exhibit a range of wettability characteristics, including water-wet, oil-wet, or mixed-wet behavior, depending on its composition, surface properties, and interactions with fluids and minerals (Mao et al., 2020; . The wettability of kerogen surfaces can influence the wetting behavior of the entire rock matrix.
