This paper provides a comprehensive review on the application of proppants to maintain
fracture permeability over the lifetime of a well based on published observations from …

Quantitative characterization of shale gas flow in fractured shale is a key problem in shale
gas extraction. In this study, 3D multi-scale structures in fractured shale were reconstructed …

Conventional flow models based on Darcy's flow physics fail to model shale gas production
data accurately. The failure to match field data and laboratory-scale evidence of non-Darcy …

Coproduction is an important measure for improving coalbed methane flow and production
efficiency in multilayer superimposed gas-bearing systems. By monitoring the reservoir …

Permeability is a fundamental property indicating the durability of cement-based materials,
predicted according to the material's pore size distribution (PSD). The random hierarchical …

It is important to research permeability models to clarify the evolution of methane seepage
from coal seams and to reduce the occurrence of gas accidents. However, existing …

Coal bed methane (CBM), the high-quality and efficient fuel, has caught the interest of many
nations as they strive for environmentally friendly development. Therefore, the efficient …

Coal and gas outburst have always been one of the principal gas energy disasters in coal
mines. Pre-extraction of coal-bed methane (CBM) is an effective method to reduce the …

The embedment of multisize proppant in fractures and the creep behavior of the shale will
affect fracture permeability, yet the combination of the two factors has not been well studied …

The permeability evolution for coal seam roof overburden subjected to high temperature
plays a significant role in efficient, clean, and safe production of underground coal …
