Reservoir heterogeneity in deep marine-continental transitional shales: the role of lithofacies and quality in the coal-bearing longtan formation, central Sichuan basin

Compared with marine shale formations, marine-terrestrial transitional shales exhibit rapid lithofacies changes. This poses significant challenges for the classification of shale lithofacies and the study of their characteristics. The Permian Longtan Formation (LTF) coal-measure shale in marine-terr...
