... A as an example, the model has been well used in pressure prediction and casing force analysis during MPC injection stage. The results show that the casing force is complicated during the injection process. The optimization of displacement can effectively alleviate casing deformation and make the bottom hole...

... conducted a geomechanical analysis of the mining layer at HPM utilizing the Hoek-Brown model. First, we calibrate the Hoek-Brown parameters through uniaxial compression tests in FLAC3D.

Finally, the technical measures solving...

.... In this paper, instead of mechanical well integrity, the performance of mud displacement using the rock-based geopolymer with different retarding additives is evaluated. The investigation includes experimental and simulated studies. In the experiments, rheological properties (i.e., shear stress-shear rate...

.../spacing, and critical slip distance. We report that discontinuities with slip-weakening friction are more prone to be reactivated and ruptured under dynamic train loadings, and the resultant shear displacements of discontinuities associated with rock block deformations and movements would further induce...

...). Loss of ground confinement results in softening of the skin of the excavation. It allows excessive displacements in radial and tangential directions, and causes considerable dilation. The situation worsens if the rock mass contains pre-existing geological discontinuities, material diversity, and water...
