Comparative Study on Pore Characteristics and Methane Adsorption Capacity of the Lower Silurian Longmaxi Shales with Different Lithofacies

Fractal and Fractional
In this study, shale samples with diverse lithofacies from the Lower Silurian Longmaxi Formation in the Fuling Field were investigated to evaluate the variations in pore characteristics and methane adsorption capacity (MAC) of different shale lithofacies.

Favourable exploration lithofacies of hybrid sedimentary shales in the Dongpu depression, Bohai Bay Basin

Frontiers in Earth Science
Hybrid sedimentary shales (HSS) are key components of continental shale oil resources. The inherent heterogeneity of HSS lead to rapid variations in oil content and mobility, complicating sweet spot prediction.
