Experimental investigation on the impact of coal fines generation and migration on coal permeability [PDF]
Journal of Petroleum Science and Engineering, 2017 Abstract Measurements of the coal fines production and the impact of these fines on the permeability of two coals from the Bowen Basin, Australia, were performed at different flow conditions (single-phase water or gas, two-phase water and gas) and pressure conditions. The fines collected from each coal samples ranged in size from 1 μm to 14 μm.

Gas Science and EngineeringThe challenge of coal fines production within tectonic coal reservoirs during coalbed methane (CBM) development in China presents a significant concern. In this study, coal samples with distinct coal structures from Hancheng mining area were selected for experiments on coal fines migration.

Integrated geomechanical, geohydraulic and geological (3G) study of coal fines generation and migration [PDF]
, 2019 Coal fines are generated during both the dewatering and Coal Seam Gas (CSG) production stages. This is due to the interaction between the fluid flow and the coal solids affixed to coal cleat surfaces. The generated coal fines may plug gas flow paths and cause the reduction of coal permeability. They may also deposit at the bottom of a well and bury the

Analysis of characteristics of coal fine production and its influence factors in Baode block [PDF]
Youqicang pingjia yu kaifa, 2023 The issue of coal fine production is increasingly prominent in the development of coal-bed methane. Implementing appropriate measures to control the migration and production of coal fines is crucial for achieving stable and high production of coal-bed ...
