This dataset comprises the input files for numerical simulation of 30-years cold water reinjection through a doublet for geothermal exploitation of a hot sedimentary aquifer (HSA) and the associated risk for reactivating distant faults. Numerical models explore the effect of fault permeability on the governing thermo-hydro-mechanical (THM) processes and the geomechanical response of the system. The models are 2D plane strain including a homogeneous and isotropic HSA laterally bounded by two opposite dipping normal faults. Following this brief explanation, the dataset has two folders, each containing data for a distinct model: - “THM_k=1e-19.gid” for simulating the geothermal system with the embedded faults having low permeability k=1·10-19 m2 - and - “THM_k=1e-16.gid” for simulating the geothermal system featured with high fault permeability k=1·10-16 m2. In each folder, there is a file with the name of the folder ended as “_gen.dat” which contains the input data of the model, including material properties, initial and boundary conditions and the time intervals. There is also a file ended as “_gri.dat” that includes the information on the mesh. The file “root.dat” includes the name of the model. To run the simulation, execute the Code_Bright executable “Cb_v9_3.exe” in a folder that contains the three input files and the executable.
