1. Preferential adsorption of hydrocarbons: Studies have shown that kerogen exhibits a strong affinity for hydrocarbons, with a higher adsorption capacity for heavier hydrocarbon molecules compared to lighter ones. This preferential adsorption can impact the composition and distribution of hydrocarbons within shale formations, influencing their potential as reservoirs for unconventional oil and gas ). 2. Effect of maturity on adsorption: The maturity level of kerogen, which refers to its degree of thermal evolution, has been found to influence its adsorption behavior. These specific findings highlight the intricate relationship between the adsorption properties of kerogen and organic shale and their role in hydrocarbon storage, migration, and extraction. Further research in this field continues to advance our understanding of these complex systems and refine the models used for reservoir characterization and production forecasting.
