Experimental study of coal fines migration characteristics in reservoirs with diverse coal structures: Influence on reservoir behavior [PDF]
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.

Gas Science and Engineering, 2023 Coalbed methane reservoirs generate coal fines during production that cause irreversible damage to cleat conductivity. In severe scenarios, this can result in temporary closure of recovery operations from the gas well(s). In this work, we simulate the impact of coal fines on proppant conductivity.

Numerical simulation study on influence of coal fines migration on porosity and permeability in cataclastic coal [PDF]
Youqicang pingjia yu kaifaDuring coalbed methane (CBM) production, coal fines within the reservoir can migrate, potentially blocking pore throats and resulting in a significant reduction in reservoir permeability. This process adversely affects the final CBM yield. To investigate
