... model. The subsurface model used in this abstract is the salt model, issued from the joint SEG/EAGE 3-D Modeling Project (SEM). The SEG/EAGE salt model is one of the geological models that is used for modeling 3-D synthetic seismic datasets. The dimensions of the model are 13.5kmx13.5kmx4.2km. It has...

... separate elementary seismic waves. The original 3-D SEG/EAGE Salt Model (Aminzadeh et al. 1997) is very complex model and cannot be directly used for ray tracing, because ray tracing computations need smooth velocity macro models (Bucha, Bulant & Klimes 2003). Is the smoothed SEG/EAGE Salt Model suitable...
