Seismic amplitudes yield key information on lithology and fluid fill, enabling interpretation of reservoir quality and likelihood of hydrocarbon presence. The modern seismic interpreter …
When transversely isotropic (VTI) media with vertical symmetry axes are characterized using the zero-dip normal moveout (NMO) velocity [V nmo (0)] and the anisotropy parameter …
As has been known for some time, velocities of elastic waves propagating in most subsurface formations exhibit directional dependence, or seismic anisotropy. On their way to …
The subject of seismic anisotropy has a long history, but only recently has it come to be seen as a central feature of geophysics, as applied to the exploration for hydrocarbons and to …
GPR and reflection seismics share common physical and methodological bases but are sensitive to different subsurface physical properties. The peculiarities of the electromagnetic …
We begin this book with a brief discussion on the basics of seismic-wave propagation as it relates to AVO, and we follow that with the rock-physics foundation for AVO analysis …

Improvements in seismic acquisition, such as the collection of long-offset and wide-azimuth data, coupled with the increase in computer power have made full waveform inversion …
We consider multiple transmitted, reflected, and converted qP-qSV-waves or multiple transmitted and reflected SH-waves in a horizontally layered medium that is transversely …

Inversion of reflection traveltimes in anisotropic media can provide estimates of anisotropic coefficients required for seismic processing and lithology discrimination. Nonhyperbolic P …
