Unravelling the impact of lithofacies on the composition of NSO compounds in residual and expelled fluids of the Barnett, Niobrara and Posidonia formations

•Clay minerals have high adsorption affinities for acidic organooxygen compounds.•Biogenic quartz preferentially preserves and retains organonitrogen species.•Oxygen and nitrogen rather than sulfur affect the retention of NSO compounds.•Alkylation features of compounds inherited from kerogen are modified by expulsion.
