We explore the fully coupled thermo-hydro-mechanical-chemical (THMC) response of CO 2
enhanced CBM recovery (CO 2-ECBM) considering the coupling relationships of …

Although the interaction of gas and coal has been comprehensively investigated in coalbed
methane (CBM) extraction process, fewer scholars have taken the effect of temperature and …

Nuclear magnetic resonance (NMR) is a commonly used method to quantitatively
characterize the pore structure of coal. T 2 cutoff value is closely related to the microscopic …

Matrix compressibility and pore properties (pore size distribution) of a rank range of coals
was investigated using mercury intrusion porosimetry (MIP) on coal cores with the pore size …

Owing to the exhaustion of shallow coal resources, deep mining has been occupied in coal
mines. Deep buried coal seams are featured by the great ground stress, high gas pressure …

This study presents the development and application of a fully coupled two-phase (methane
and water) flow, transport, and poromechanics numerical model for the analysis of …

Low-permeability coalbed-methane (CBM) reservoirs possess unique pressure-propagation
behavior, which can be classified further as the expansion characteristics of the drainage …

Exploration and development of coalbed methane (CBM) reservoirs is ongoing in the Asia
Pacific region, with low permeability, undersaturated coals being the target in some areas …

Understanding the relative permeability characteristics of coal in a gas-water system is
crucial for coalbed methane development. Due to a lack of experimental information on the …

Hydraulic fracturing is an efficiency approach to improve underground gas drainage.
Although the interaction of fluid and coal has been comprehensively investigated in …
