Type II-S kerogen source rock plugs with high TOC contents (10 to 20 wt.%) were investigated in their initial immature state as well as in different thermal maturities induced by hydrous pyrolysis under both unstressed and stressed conditions in order to investigate hydrocarbon generation and primary migration. Applied methods comprise organic geochemical investigations to assess the state of kerogen conversion as well as visual techniques such as reflected light microscopy and BIB-SEM to investigate the distribution and evolution of kerogen, solid bitumen and pore space within these rocks. Our first results indicate that primary migration within such high TOC rocks occurs along an interconected porenetwork that evolves upon kerogen conversion rather than due to the buildup of overpressure and microfracturing.
