The model shows migration pathways and present-day accumulations on the BCU surface in the southern Halten region. The best-fit of accumulation size and type to observations is obtained only when a multi-stage model with evolving fault properties is used. Additionally, hydrocarbon GOR in accumulations is improved when the complex thermal evolution of  sediments obtained from a basin model (TecMod) is implemented (Iyer et al., 2016, submitted).
