In the process of long-term water flooding in the Gaoqian Southern Area with an average porosity of 30% and an average permeability of 1333.5×10−3 μm2, the fluid-solid interaction among oil, water, and rock has a great influence on the pore struc

The low permeability and submicron throats in most shale or tight sandstone reservoirs have a significant impact on microscale flow. The flow characteristics can be described with difficultly by the conventional Darcy flow in low-permeability reservo

This paper presents a combined experimental–analytical investigation of coal strain development under fluctuating applied hydrostatic stress. The laboratory setup mimics the isotropic volumetric compaction of coal under burial–uplift cycles in th

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 co

This study presents a systematic experimental methodology to investigate permeability damage caused by fines migration. The workflow starts with a thorough characterization of a bituminous coal sample by the XRD, SEM-EDX, petrographic, proximate and

Produced water during coal seam gas (CSG) production carries fines. A few laboratory studies reported in open media suggest that fines migration can cause variation in coal permeability during water flow. However, a detailed laboratory study has not

Image-based computations of relative permeability require a description of fluid distributions in the pore space. Usually the fluid distributions are computed on the imaged pore space. Recent advances in imaging technologies have made it possible to

This paper presents an experimental and modelling study of the adsorption/desorption of pure gases CH4, CO2 and N2 and their binary and ternary mixtures on coal samples obtained from southeast Qinshui Basin, China. Results show that the adsorbed amou

Coal seam gas (CSG) production involves water flow through coal cleats. Creep effect and fines migration can cause a severe damage to coal permeability during water flow. This study presents a systematic methodology to analyze coupled effect of creep
