A damping method for the computation of the 2.5-D Green's function for arbitrary acoustic media
In acoustic wavefield modelling, the 2.5-D approximation, in which the model parameter is considered to be invariant in the strike direction and the source is assumed to be a point excitation so that the wavefield has 3-D features, is an economical and realistic scheme for seismic full-waveform ...

Crosshole seismic inversion with normalized full‐waveform amplitude data
We investigate a simple scheme for full‐waveform amplitude spectrum inversion of crosshole seismic data with an unknown source wavelet. The method is based on our 2D/2.5D finite‐element method of acoustic‐wave modeling. The normalized amplitude data, defined as the spectral ratio of the original trace ...

Prestack multicomponent migration
Prestack elastic migration by displacement potential extrapolation is a mixed, systematic, and function‐blocked vector wavefield migration algorithm. A new wavefield extrapolation method for inhomogeneous media is introduced here according to the following sequence: displacements ← potentials ← extrapolation of the potentials ← displacements, which is relatively accurate and not computer‐time ...

Transient solution for poro-viscoacoustic wave propagation in double porosity media and its limitations
The analytical transient acoustic solution and dispersion characteristics for the double-porosity model are obtained over the whole frequency range for a homogeneous medium. The solution is also obtained by approximating the double porosity model with a uniform poro-viscoacoustic model and then ...

Surface seismic imaging by multi-frequency amplitude inversion
We have developed a new full-waveform inversion scheme for crosshole seismic imaging. In this paper, we adapt it to surface seismic imaging in which only the spectral amplitudes are used. We perform numerical experiments to test the known source signature algorithm (KSS) against two other inversion schemes?one which estimates the source signature from the shot gathers (ESS) and the other which ...
