Coal, containing all the elements that are present in nature and more than 200 minerals, has
a complex chemical structure, making it one of the most complex geological materials …

Research on pyrolysis mechanisms has attracted significant attention as they can efficiently
assist in coal resource utilization. Although experimental techniques have significant …

Free hydrogen detected in the Songke-2 well (Songliao Basin, China) has a strong crustal
contribution. Here we evaluate whether the source could be the organic matter in Lower …

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 …

Geological formations are suitable locations for CO 2 sequestration, and among them, coals
are excellent targets because of their nanoporous structure, which leads to a high gas …

The multifractal characteristics of pore structures of low-, middle-, and high-rank coals were
analyzed in this study based on the results of high-pressure mercury injection analysis and …

This review examines new techniques and applications of organic petrography in source-
rock reservoir petroleum systems that have occurred along with development of the global …

We have recently shown that molecular hydrogen generation from organic matter occurs at
high maturity levels (vitrinite reflectance 3–5%) in Lower Cretaceous shales of the Songliao …

Understanding pore heterogeneity is essential to obtain insights into the gas storage,
transport, and recovery from coal. The pore structure in analytical sample particles of …

The determination of adsorption phase density significantly influences the assessment of
gas occurrence state and gas content within in-situ reservoirs, particularly for the evaluation …
