Hydrocarbon generation results from computerized 1-D basin [[modeling]] software are typically presented as either open- or closed-system yields. '''Open-system''' models are based on the assumption that hydrocarbons have been expelled from the source rock, have been transported away, and are no longer subject to the thermal conditions of the 1-D model. '''Closed-system''' models assume the hydrocarbons have not been expelled from the source rock and that all generated hydrocarbon phases are subject to further cracking to lighter phases.
