To clarify how shale-reservoir heterogeneity constrains hydraulic-fracturing effectiveness in complex structural areas, this study analyzes exploration well X in the Mugan–Shoushan area, Yunnan Province, using organic geochemistry, petrology and mineralogy, reservoir-property, and rock-mechanical data from the Wufeng–L...
Coal gangue aggregate has high water absorption and a porous microstructure, both of which can reduce the mechanical performance of coal gangue concrete (CGC). This study examined whether hooked steel fibers can compensate for this strength loss and improve the mechanical behavior of steel fiber-reinforced coal gangu...

China’s deep coalbed methane (CBM) resources hold significant development potential, yet their commercial exploitation remains hindered by four interrelated reservoir challenges: substantial burial depth, elevated in situ stress, ultra-low matrix permeability, and pronounced stress-dependent permeability decline. These...
