Recent advances in parameter estimation and seismic processing have allowed
incorporation of anisotropic models into a wide range of seismic methods. In particular …

The accurate determination of seismic attenuation, or 1/Q, is useful for signal enhancement
and reservoir characterization. To arrive at the necessary accuracy however, a number of …

A conventional amplitude variation with offset (AVO) inversion is based on geometrical
seismics which exploit plane-wave reflection coefficients to describe the reflection …

Near-and postcritical (wide-angle) reflections provide the potential for velocity and density
inversion because of their large amplitudes and phase-shifted waveforms. We tested using …

We have performed a multidisciplinary geophysical survey combined with geotechnical
investigations over a degrading alpine rock glacier. A dense grid of helicopter-borne ground …

Spherical-wave offset-dependent reflectivity is investigated by measuring ultrasonic
reflection amplitudes from a water/Plexiglas interface. The experimental results show …

Plane-wave reflection coefficients (PWRCs) are routinely used in amplitude-variation-with-
offset analysis and for generating boundary data in Kirchhoff modeling. However, the …

Reflection and transmission (R/T) responses characterize the energy distributions for
incident and generated waves across the subsurface interface. The R/T coefficients are …

In the past, various approximations to the Zoeppritz equations have been derived and used
in conventional AVO inversion. These approximations have accuracy limited to small angles …

Existing amplitude variation with offset (AVO) and slowness (AVS) theories fail to interpret
observed amplitudes in terms of actual elastic properties of the media for a reflection event …
