Abstract
A fault aseismic slip induced by fluid injection into the fault in homogeneous elastic low-permeable medium is considered numerically with the help of Embedded Discrete Fracture Model (EDFM). Modified two-parameter rate-and-state law was used to model the dynamics of the fault slip. The influence of the two-parametric friction law parameters and the rock filtration properties on the fault slip was considered. It was shown that the fault normal stiffness and remote shear stress resolved on the fault plane have the greatest impact on the fault deformation. It was found that the fault behavior is different for cases of impermeable and low-permeable matrix.
