Coal seam gas (CSG), also known as coalbed methane (CBM), is an important source of
gas supply to the liquefied natural gas (LNG) exporting facilities in eastern Australia and to …

Coal fines can substantially influence coal seam gas reservoir permeability, thus impeding
the flow of gas in coal microstructure. The coal fines generation and migration are influenced …

Horizontal boreholes have been widely used to extract natural gas from coal seams.
However, these boreholes can encounter severe instability issues leading to production …

Depleted coal seam gas reservoirs are considered as one of the best sites for underground
CO 2 sequestration which can contribute to climate change mitigation. Due to coal's high …

Several coal seams are contained within the formations of Great Artesian Basin (GAB), the
largest natural underground water reservoir in Australia and the world. The extraction of coal …

Coal permeability is significantly stress-dependent and changes during gas production. In
the previous studies, less attention has been paid to the impact of desorption radius and its …

The stability of the wellbore in multibranch horizontal wells is a critical issue that significantly
impacts gas production and service life. To gain a more comprehensive understanding of …

The dynamic permeability of coal reservoirs is more complicated than that of conventional
reservoirs because of the natural cleat system and matrix shrinkage induced by methane …

During the production process of coalbed methane, the generation and migration of coal
fines can obstruct fractures in coal reservoirs and reduce their permeability. In order to …

The wellbore instability of the deep coal seam has always been a difficult problem limiting
drilling engineering in Dibei area of Tarim basin, China. Therefore, the mechanisms of …
