Shale microstructure determines hydrocarbon reserves and productivity. However, despite
its high economic importance, the shale microstructure remains poorly understood. This is …

There has been a long history of using X-rays to visualize coal and its transitions during
various treatments. Advances and improved availability has allowed the application of X-ray …

To describe a low-field nuclear magnetic resonance (NMR) method for quantifying pore–
fracture fractal dimensions and their influence on effective porosity and permeability, we …

Pore-throat size is a very crucial factor controlling the reservoir quality and oiliness of tight
sandstones, which primarily affects rock-properties such as permeability and drainage …

The structure and fractal characteristic of micro-(0.32∼ 2 nm) and meso-pores (2–50 nm) in
low, middle-rank (maximum vitrinite reflectance, R o, max= 0.65–1.34%) tectonic deformed …

This paper reviews recent developments on the cleat-scale characterisation of coal. Novel
micro-CT imaging and image calibration methods are described. The application of micro …

Predicting the mechanical performance of concrete from composition and processing
remains a grand challenge. Our work focuses on predicting damage evolution in ultrahigh …

X-ray computed tomography (XCT) is a powerful 3D imaging technique that has been used
to investigate meteorites, mission-returned samples, and other planetary materials of all …

The evaluation of pore-throat structure is essential for the exploration and exploitation of
tight oil and gas reservoirs. In this study, various experiments such as casting thin section …

Coalbed methane (CBM) is a form of natural gas that is extracted from coalbeds.
Characterization of CBMs is very challenging mostly due to the very complex fracture system …
