... ABSTRACT Fine-grained sediments, mudrocks and shales have unique fabric and pore topology that reflect their mineral composition and formation history. Atomic-scale clay-clay electrical interactions coexist with the micron-scale mechanical interactions between silicate and carbonate grains...

... ABSTRACT Stress-dependent behavior of permeability is an important characteristic of fluid flow through porous medium. It is widely accepted that the stress-dependent permeability behavior relates to pore volume change, but ignore the real stress distribution around pores. In this study...

... the connections to locate additional geothermal energy sources in the future. The study used several methods to estimate rock physics characteristics, including elastic modulus of minerals and rock pore shape and found that the intra-particle model matches the available data. INTRODUCTION The Lodgepole...

Silty mudstone has a certain permeability and water absorption characteristics between mudstone and argillaceous siltstone, and there is a phenomenon of fluid pressure transmission in the pores. The water absorption characteristic...

... distribution curves of the two rock samples under different relative humidity were obtained by nuclear magnetic resonance (NMR) technology. Comparing the T2 distribution curves of different relative humidity, it is found that the pores of shale are dominated by small pores, while the pores of sandstone...

... ABSTRACT: Microbially induced calcite precipitation (MICP) is a ground improvement technique where the metabolic activities of bacteria are utilized to produce calcium carbonate precipitants at the grain contacts or within the pore spaces, enhancing bonding between the soil particles thus...
