Abstract Characterization of pore systems in subsurface systems is of great importance for
predicting the properties of rocks and classifying the subsurface systems. Geometric features …

Fluid-saturated porous media are two-phase media, which are composed of solid and liquid
phases. Biot theory for fluid-saturated porous media holds that underground media are …

The multifractal characteristics of pore structures of low-, middle-, and high-rank coals were
analyzed in this study based on the results of high-pressure mercury injection analysis and …

It is useful in the clarifications of pore spaces at different scales in reservoir evaluations, and
also helpful to exploit shale oil resources. The analysis of pores and fractures can be used to …

Scanning electron microscopy (SEM) is one of the most prevalent methods used to image
and quantify the pore size distribution of shale rock, critical in understanding unconventional …

As a highly heterogeneous material, the porous structure of coal is usually described by
fractal dimension, which generally can be obtained by gas adsorption, light scattering and …

Enhanced and efficient recovery of coalbed methane (CBM) is essential to prevent mine
disasters and utilize unconventional gas resources. In this study, hydraulic slotting (HS) …

The 3D digital core was reconstructed based on a CT scanning test, and the digital cores
seepage simulation was investigated to study the shale's microscopic seepage …

In the realm of gas field development and CO 2/H 2 geological storage, the precise
characterization of reservoir parameters stands as a critical role. In recent years, digital rock …

Pore type is a crucial consideration in the quantification of shale pores. Convolutional
Neural Networks (CNNs) are widely used for identifying pore types in shale, but it is …
