Chemical stimulation is a potential technology for coal permeability enhancement.
Develo** chemical stimulation techniques and understanding its mechanism are …

Coalbed methane (CBM) is a form of natural gas that is extracted from coalbeds.
Characterization of CBMs is very challenging mostly due to the very complex fracture system …

Microwave heating contributes to coal fracturing and gas desorption. However, problems of
low penetration depth, local overheating and fracture closure exist. Coal demineralisation by …

Abstract Characterization of pore systems in subsurface systems is of great importance for
predicting the properties of rocks and classifying the subsurface systems. Geometric features …

Characterization of microscopic structure and macroscopic physical property are the basis
for better understanding of coalbed methane reservoirs. X-ray computed tomography (CT) …

Pore systems become very complex in heterogeneous reservoirs such as low-permeability
and tight sandstones for macropores and micropores both exist in such reservoirs. Although …

The micropore structure of coal has a significant impact on gas seepage in a coal reservoir.
In this study, the micropore structure of coal was reconstructed and then quantitatively …

Temperature change in coal will lead to the expansion and propagation of micro-cracks, and
this progressive temperature-induced failure is defined as thermal damage. Understanding …

The sensitivity of coal reservoir is an essential reason decreasing the coalbed methane
(CBM) production during the CBM development. Whether the acid sensitivity is a negative or …

Accurate modeling of shale samples is very crucial for evaluating and predicting the physical
properties. However, obtaining large-scale and high-resolution images of shales using a …
