Characteristics of coal fine deposition and migration in coalbed methane wells during gas production stage

Physics of Fluids
The migration, deposition, and retention of coal fines carried by drainage fluids in gas production wells of coalbed methane (CBM) wells severely restrict CBM production. This study establishes a numerical model to investigate the coupled gas–liquid–coal fines seepage law in the horizontal wellbore annulus during gas production stage using a ...

Coupled fluid flow-geomechanics simulation in stress-sensitive coal and shale reservoirs: Impact of desorption-induced stresses, shear failure, and fines migration

Fuel, 2017
Abstract Long-term pore pressure depletion significantly alters reservoir stresses, which are known to have a substantial impact on permeability in fractured reservoirs. Increased effective stresses resulting from depletion often induce a decrease in permeability.

A laboratory study of the effect of creep and fines migration on coal permeability during single-phase flow

International Journal of Coal Geology, 2018
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 ...
