Scientific paper

Laboratory experiments were performed to assess diffusion through kerogen as a mechanism of liquid hydrocarbon transport through fine-grained rocks. Such transport can be important in primary migration within source rocks and in leakage through seals. Previous work with organic-coated model cores has shown that hydrocarbon diffusion through organic matter networks can be substantially greater than hydrocarbon diffusion through aqueous pore space. In the present work, natural kerogen networks were evaluated. Experiments with five natural source rocks showed that kerogen increased the experimental hydrocarbon flux over the calculated hydrocarbon flux through pore water in only one of these source rocks, the richest (2.2% TOC) carbonate sample. Effective diffusivities through kerogen were calculated for the two experimental hydrocarbons through this sample. The results were extended with the Wilke-Chang correlation to yield diffusivities of several other hydrocarbons through similar source rocks.
