Hierarchical integration of porosity in shales [PDF]
Scientific Reports, 2018 Pore characterization in shales is challenging owing to the wide range of pore sizes and types present. Haynesville-Bossier shale (USA) was sampled as a typical clay-bearing siliceous, organic-rich, gas-mature shale and characterized over pore diameters ...

Porosity, -porosity and measures [PDF]
Nonlinearity, 2002 We show that given a σ-finite Borel regular measure μ in a metric space X, every σ-porous subset of X of finite measure can be approximated by strongly porous sets. It follows that every σ-porous set is the union of a σ-strongly porous set and a μ-null set.

Innovative Material Can Mimic Coral and Boulder Reefs Properties
Frontiers in Marine Science, 2021 Low-Voltage Mineral Deposition technology (LVMD), widely known as Biorock, has previously been suggested as support for coral reef restoration, as hypothesized high porosity, wide pore-size distribution and connectivity, and good strength properties may ...

Variation of Open-Pit Waste Dump Specimens Under Effective Pressure Influence
Frontiers in Earth Science, 2021 The waste dump is a giant artificial loose pile body composed of fine, medium, and coarse particle sizes. Rising incidents of landslides caused by overburden pressure and effective pressure are of increasing concern in the open-pit waste dump and, if not

A modified pulse‐decay approach to simultaneously measure permeability and porosity of tight rocks
Energy Science & Engineering, 2021 Permeability and porosity are the two most important parameters of rocks for the evaluation and exploitation of oil/gas reservoirs. In this study, a modified pulse‐decay method has been developed to measure both permeability and porosity simultaneously ...
