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 ...

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 ...
