Analysis of rock microstructure after CO2 breakthrough based on CT scanning
The alteration of mudstone’s microscopic properties within the caprock in CO 2 geological storage determines the effect of storage. One of the crucial...

Seepage-related characteristics of weak interlayer suffering from a physically-chemically mediated erosion in grotto relics
The coexistence of the weak interlayer and groundwater could give rise to an undesirable geological condition, resulting in seepage-induced hazards,...
