Migration mechanism of grouting slurry and permeability reduction in mining fractured rock mass [PDF]
In order to solve the water and gas discharge hazard caused by gob water and harmful gases (such as CO), the method of grouting overburden fractures is adopted to achieve the purpose of safe and efficient mining production in coal mines.

Effect of hydrate nucleation mechanisms and capillarity on permeability reduction in granular media
A model for water permeability reduction in hydrate‐bearing sediments is presented by considering capillary effect in hydrate nucleation. Both grain‐coating and pore‐filling cases are considered.

Applications of zeolite-zirconia-copper nanocomposites as a new asphaltene inhibitor for improving permeability reduction during CO2 flooding. [PDF]
Using nanoparticles for adsorbing asphaltene was known as an efficient method among researchers for crude oil upgrading. In this study, zeolite-zirconia-copper nanocomposites (NCs) have been synthesized and characterized with Scanning electron microscopy

Factors Affecting Permeability Reduction of MICP for Fractured Rock
Microbial induced calcite precipitation (MICP) has shown great potential to reduce the permeability of fractured rock, but its permeability reduction characteristic, affected by cementing solution concentration and geometric morphology of fractured rock,

Dissolution-Driven Permeability Reduction of a Fractured Carbonate Caprock. [PDF]
Geochemical reactions may alter the permeability of leakage pathways in caprocks, which serve a critical role in confining CO2 in geologic carbon sequestration. A caprock specimen from a carbonate formation in the Michigan sedimentary Basin was fractured and studied in a high-pressure core flow experiment. Inflowing brine was saturated with CO2 at 40°C
