Water plays significant roles in shale gas accumulation and extraction, yet the interactions between water kerogen are still unclear due to complexity of natural pore system molecular structure kerogen. This study investigates adsorption mechanism vapor by analyzing dynamic sorption (DVS) experimental results, combined with simulations based on a realistic model Marcellus Pore characteristics from low-pressure nitrogen carbon dioxide adsorption, as well scanning electron microscopy, were used further understand adsorption. The simulation results reveal that condensation exhibits size effect. condenses more readily pores smaller than 1.5 nm, while larger pores, it primarily adsorbs surface. Within kerogen, vast majority resides micropores matrix. Mesopores macropores occupy ∼10% total specific surface area, less 5% molecules adsorbed surfaces mesopores macropores. DVS experiments indicate amount increases rapidly when relative humidity exceeds 80%. Molecular show this increase is ultra-micropores (<1 nm) free space not conducive vapor.
