The rapid development of shale oil and gas promotes the plentiful research and
characterization of micro-nano pore structure, and accumulates massive data, which is vital …

Abstract Scanning Electron Microscopy (SEM) and Atomic Force Microscope (AFM), two
easily acquired and widely applied image acquisition and analysis methods, have rarely …

Liquid nitrogen (LN2) is an important means to improve the permeability of coal reservoirs.
The LN2 soaking method has a wide range of application prospects. However, not enough …

Liquid carbon dioxide phase change fracturing (LCPCF) technology can effectively increase
the coal permeability. In order to evaluate the influence of LCPCF on pore structure and …

Coal pores are the locations of coalbed methane occurrence and enrichment and the main
storage space targeted in CO2 sequestration. The systematic investigation of the coal pore …

Quantitative characterization of nanopore structure is of great importance for both accurate
assessment of gas reservoir capacity and gas migration behaviors. In this work, atomic force …

Water is widely distributed in coal under the in-situ reservoir conditions, which has a great
impact on gas adsorption and migration within coal. In this work, methane sorption behavior …

The influence of supercritical CO 2 (SC-CO 2) fluids on pore structure characteristics of coal
plays a vital role in geo-sequestration of CO 2 into deep coal seams. Changes in coal pore …

To explore a comprehensive evaluation method for saline lacustrine shale, samples were
collected from the shale strata of the Lucaogou Formation in the Jimusar Sag, Junggar …
