Accurate characterization and visualization of the complex inner structure and stress
distribution of rocks are of vital significance to solve a variety of underground engineering …

Abstract The Vereiskiy reservoir (Perm Region, Russia) is one of the complicated oil-bearing
carbonate formations. It consists of interbedded carbonates and clayey rocks with low …

Physical properties of some weathered/altered volcanic rocks and their variation with the
degree of alteration are described in detail. A series of tests was performed to identify and …

Despite the prevalence of thin section analysis in studies of Quaternary sediments, there are
limitations associated with the production of thin sections (sediment modification) and the …

Determining the seepage characteristics of coral reef limestone is highly significant for
engineering activities on relevant strata. In this paper, the pore structure information of two …

The mechanical heterogeneity of unconventional gas reservoirs is a significant factor
affecting the nucleation and propagation of hydraulic fractures. The ignorance of mechanical …

X-ray computed tomography (XRCT) can reconstruct, in a nondestructive way and in three-
dimension, the distribution of densities within opaque materials. Consequently, it provides …

Rising temperature will cause the changes of pore characteristics and strength property in
rock. This research takes the limestone produced in Taihang Mountains as the research …

The irregularity and multi-scale features are the most important and intrinsic characteristics
for rocks, which are caused by the variety of microstructures. In this paper, a novel …

Although computed tomography (CT-Scanning) has been regularly applied to core analyses
in petroleum geology, there is still a need to improve our ways to document porosity and …
