Cost-effective pore characterization is essential for understanding gas storage and flow in
shale reservoirs. Herein, we thoroughly investigated the pore structure of Qiongzhusi shale …

The mechanical properties of shale are critical for the extraction of gas and oil from
nanoporous shale. In this study, nanoindentation tests with the accelerated property …

The investigation of water's flow behavior in nanoporous shale media is fundamental to the
high-efficiency exploitation of shale gas reservoirs. Such an investigation can provide crucial …

High-pressure methane sorption isotherms at 40–101° C and pressures up to 25 MPa were
measured on Jurassic lacustrine and Silurian marine shales from China. Shale samples …

As a non-destructive method, the proton nuclear magnetic resonance (1H NMR) technique
with low echo time (TE, eg, 0.07 ms) has been increasingly used for characterizing full pore …

The atomic-scale surface fractal, which can notably affect gas adsorption, is a prominent
form of geometric heterogeneity at the surfaces of the pore structure of shale. Systematically …

In recent years, unconventional reservoirs have drawn tremendous attention worldwide. This
special issue collects a series of recent works on various fractal-based approaches in …

The heterogeneity of pore system of deep shale reservoir determines the occurrence,
enrichment and migration behavior of shale gas within shales. In this study, multi-fractal …

Characterization of pore structure and heterogeneity is crucial for exploring and evaluating
shale oil and gas resources. Existing methodologies exhibit various limitations, and intuitive …
