“…The complex environment of high ground stress, high ground temperature, high osmotic pressure, and strong mining disturbance makes the instability of confining pressure and rock burst inevitable. In fact, in high ground stress, impact load, and stress pulse are the key factors to promote the failure of engineering rock mass (El‐Amin et al, 2019; Fan et al, 2021; Lu et al, 2022; Wang et al, 2018).…”

The hydrostatic or confining pressure of deep rocks has a significant impact on the mechanical behavior of brittle materials. Especially when confining pressure is applied, the mechanical properties of rock materials will undergo significant changes. Considering that the process of shale sample subjected to impact load is in a closed container in the dynamic triaxial SHPB test, the failure process of the sample cannot be observed. Meanwhile, the activation volume of the shale sample would be large and local failure would occur in the test under the high strain rate loading. Therefore, the finite element model of shale considering the bedding effect under confining pressure was established in this study. Taking shale materials with different bedding dip angles as simulation objects, the dynamic failure characteristics of shale were studied using the dynamic analysis software ANSYS/LS‐DYNA from three aspects: stress‐strain curve, failure growth process, and failure morphology. The research results obtained can serve as the key technical parameters for deep resource extraction.

“…El-Amin et al [22] have used the MFEM with stability analysis to simulate the problem of natural gas transport in a low-permeability reservoir without considering fractures. The authors [23] extended their work to cover fractured porous media and the rock stress-sensitivity with considered stability analysis of the MFEM. In this work, we present a theoretical basis with proofs of the stability analysis of the MFEM (in Ref.…”

In this work, we introduce a theoretical foundation of the stability analysis of the mixed finite element solution to the problem of shale-gas transport in fractured porous media with geomechanical effects. The differential system was solved numerically by the Mixed Finite Element Method (MFEM). The results include seven lemmas and a theorem with rigorous mathematical proofs. The stability analysis presents the boundedness condition of the MFE solution.

The present work is dedicated to studying the transfer of natural gas in shale formations. The governing model was developed on the basis of the model of dual-porosity dual-permeability (DPDP). The mixed finite element method (MFEM) is employed to solve the governing equations numerically. Numerical example is presented and results discussed such as production cumulative rate, pressure and apparent permeability.
