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 …

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

Coal is highly anisotropic and heterogeneous, affecting coal permeability. As permeability is
one of the most important reservoir properties for coalbed methane production, it is useful to …

A comprehensive analysis of crack initiation and propagation in coal is critical for
understanding its mechanical behavior and its impact on permeability. The finite element …

Microstructural evolution in coal due to CO 2 injection directly influences the gas transport
and storage properties of coal during CO 2 sequestration in deep coal seams. Using …

A blasting experiment was conducted on iron ore samples by considering multiple coupling
charge coefficients. The resulting internal fracture and damage characteristics were …

Coal porosity and permeability are highly stress-sensitive. Although the stress-dependent
permeability behaviour of coal has been well documented in the literature, few studies are …

Accurate characterization of the compressibility of pores and fractures in coal reservoirs is of
great significance for predicting permeability and for optimizing the production of coalbed …

Polymer flooding is an important tertiary recovery method. However, even after its
application, more than 50% of the oil remains in the formation layers. It is thus important for …

Gas flow in coal cleats plays a significant role for the permeability of coal seams.
Investigations of gas transport in coal are carried out in this work using a numerical scheme …
