Pore Structure and Heterogeneity in the Lacustrine Shale of the Second Member of the Paleogene Funing Formation, Subei Basin, China

Minerals
Characterization of pore structure and heterogeneity is crucial for exploring and evaluating shale oil and gas resources. Existing methodologies exhibit various limitations, and intuitive, quantitative description techniques are lacking. To address these issues, shales from the second member of the Funing Formation (E1f2) in the Subei Basin were ...
