An experimental study of coal-fines migration in Coalbed-methane production wells
Journal of Natural Gas Science and Engineering, 2015Abstract Coalbed Methane (CBM) has become an important gas resource in the last several decades. The brittle property of coal matrix and overflushing operation make the migration of coal fines inevitable. As the liquid flows below a critical velocity, the coal-fines accumulate in the bottomhole.

Modeling of Coal Fine Migration During CBM Production in High-Rank Coal
Transport in Porous Media, 2017During CBM (coalbed methane) production, the interaction of coal fracture surface with water flow commonly generates and starts coal fine flow. Part of flowing coal fines deposit in coal fracture system due to water production reduction and methane production increase.

Abstract Both fines migration and creep can damage coal permeability during coal seam gas production. This study investigates the individual and coupled effect of fines migration and creep on coal permeability. We perform three types of flow experiments on coal samples: (1) water flow with both fines migration and creep, (2) gas flow with creep and ...

Abstract The vibrated dense medium fluidized bed is an efficient waterless dry coal separation technology. In order to reduce the interference of the macroscopic migration of the entire bed with the coal settlement process, the material composition and diffusion behavior of the binary medium are studied.
