... poro-elasto-dynamic model is developed to examine the effects of pump start-up on borehole stability. Firstly, a transient hydraulic model is developed to predict the temporal variation of pressure in flow conduits during the pump ramp-up periods. A constitutive equation is used to describe the time...

..., and induced seismicity risks. The numerical implementation of the governing equations for thermo-hydro-mechanical-chemical response is challenging due to the substantial contrast between the characteristic times of coupled processes. Furthermore, addressing the heterogeneity and anisotropy of geological...

... to the ultimate collapse of the fracture. The asymptotic analysis performed in (Peirce and Detournay, 2022c) establishes that the existence of the sunset solution is due to a fundamental decoupling of the kinematics from the dynamics in the governing equations, which leads to a robust way to measure the Carter...
