[Dataset] To bleed-off or not to bleed-off?

This dataset corresponds to the model made from the EGS project of Basel (2006, Switzerland). The model is solving coupled hydromechanical problem for 2D fault network on a surface of 1 km2, located at 4630-meters depth coinciding with the injection depth in the crystalline basement at Basel. A set of faults are embedded in a rock matrix, with the fault network derived from the induced seismicity that was monitored in the range of 3750 and 4750 meters deep. The maximum principal stress S_Hmax is aligned with y-axis (S_Hmax=160 MPa, S_hmin=84 MPa, S_v=115 MPa). The hydrostatic pressure is set at 45 MPa following a hydrostatic profile and the temperature at the depth of the reservoir is set at 190°C. Stimulation parameters are inputs as wellhead pressure based on the injection strategy from Häring et al. (2008), injection fluid is water. - “ .gid” is the Code_Bright file with the model of Basel. The file “_gen.dat” contains the input data of the model (including material properties, initial and boundary conditions and the time intervals). The file “_gri.dat” includes the information on the mesh. The “root.dat” includes the name of the model. To run simulations, execute the Code_Bright executable “Cb_2020_21.exe” in a folder that contains the three input files and the executable, where X and Y denote the used version of the executable. • V13_C_NW_longbleed.gid corresponds to the model in which the bleed-off of the well is imposed. • V13_C_NW_shutin.gid corresponds to the model in which the injection well is shut-in.
