Study on Deformation and Permeation Properties of Gas-Containing Fractured Rock by Yushun Yang, Dongming Zhang, Shujian Li

“…In this paper, we investigated the gas permeation properties of fractured rock during the process of stage load axial stress and cyclic load and unload confining pressure and come to some conclusions as follows: (1) the relationship between radial strain and deviatoric stress satisfied the quadratic polynomial function, and the relationship between permeability and deviatoric stress satisfied the exponential function under different axial stress levels; (2) in the staged load axial stress process, the axial strain-deviatoric curves of specimens conform to the quadratic polynomial function. …”

Experimental Research of the Influence of Microfracture Morphology on Permeability of Shale Rock by Xiaohe Huang, Yunqian Long, Yuyi Wang, Ming Yue

“…The permeability variation of shale gas reservoir after fracturing is inevitable, while the influence of fracture length and fracture width on permeability and seepage characteristics of shale rock is a mystery. Besides, the stress sensitivity characteristics of shale rock, derived from different initial permeability, with the same permeability after fracturing are also ambiguous. …”
