The absorption (anelastic attenuation) and anisotropy properties of subsurface media jointly
affect the seismic wave propagation and the quality of migration imaging. Anisotropic …

Microtremor measurements and the horizontal-to-vertical spectral ratio (HVSR) technique,
generally used for site effect studies as well as to determine the thickness of soft …

Naturally fractured reservoirs are becoming increasingly important for oil and gas
exploration in many areas of the world. Because fractures may control the permeability of a …

We develop a non-conformal mesh discontinuous Galerkin (DG) pseudospectral time
domain (PSTD) method for 3-D elastic wave scattering problems with arbitrary fracture …

We have formulated and implemented a discontinuous Galerkin method (DGM) for elastic
wave propagation that allows for discontinuities in the displacement field to simulate …

We present an algorithm for the numerical simulation of seismic wave propagation in models
with a complex near surface part and free surface topography. The approach is based on the …

Seismic anisotropy is the fundamental phenomenon of wave propagation in the earth's
interior. Numerical modeling of wave behavior is critical for exploration and global …

Forward modeling of seismic wave propagation is crucial for the realization of reverse time
migration (RTM) and full waveform inversion (FWI) in attenuating transversely isotropic …

This paper presents an original approach to local time–space grid refinement for the
numerical simulation of wave propagation in models with localized clusters of micro …

Understanding the mechanisms of wave-induced fluid flow in the pore space combined with
attenuation and dispersion measurements may be used to estimate rock hydraulic …
