The evolution of nanopores when highly-matured or over-matured shales encounter secondary hydrocarbons was characterised in two groups of Paleozoic marine shale samples. The samples were subjected to hydrous pyrolysis to investigate the evolution of organic-hosted pores and mineral-hosted pores. The...
