ERTH 715 Seismic Modelling and Imaging
Seismic modelling is a fundamental tool being used for both seismic interpretation and processing. Numerical simulations for the seismic wave propagation in the Earth are required to validate the possible Earth models that fit available geophysical and geological data. A quantitative analysis of observable phenomena in synthetic Earth models can contribute also to the acquisition planning, especially when complex 3D geometries and rheologies are involved, as anisotropic, viscoelastic and poro-elastic effects. Seismic modeling is an important component of advanced algorithms for seismic imaging, such as reverse-time migration, multiple attenuation, non-linear diffraction tomography and full-waveform inversion. Full-waveform modeling is based commonly on three methods: finite-difference, finite-element and spectral methods. Other methods are based on the ray theory, which still allows estimating travel times and amplitudes in complex geological models.
