... on the spectral element method (SEM) and extended to Schoenberg’s linear slip model (LSM). SEM is very effective in terms of accuracy and stability criteria. LSM is treated as a boundary condition and perfectly fits for modelling fractures with a small aperture. The method is implemented for 3D heterogeneous...

... and Gao, 2009) and geothermal reservoirs (Wu et al., 2002, and references therein). In order to detect fractures in the subsurface we have to rely on seismic data. The presence of fractures produce the following wave phenomena: seismic anisotropy (Schoenberg and Douma, 1988), phase shifting, frequency...
