A comparison between one‐way and two‐way wave‐equation migration

Geophysics, 2004
Abstract Results for wave-equation migration in the frequency domain using the constant-density acoustic two-way wave equation have been compared to images obtained by its one-way approximation. The two-way approach produces more accurate reflector amplitudes and provides superior imaging of steep flanks.

A two-way nonreflecting wave equation

Geophysics, 1984
Abstract Highly reduced reflection coefficients for transmission across material boundaries. For homogeneous regions of space, however, this wave equation becomes identical to the full acoustic wave equation. Possible applications of this wave equation for forward modeling and for migration are illustrated with simple models ...

One‐way and two‐way wave‐equation migration

SEG Technical Program Expanded Abstracts 2003, 2003
We present a comparison of results for wave-equation migration in the frequency domain using the constantdensity acoustic “two-way” wave equation and its one-way approximation. The examples are based on synthetic and real data for a two-dimensional spatial geometry.

Image‐domain waveform tomography with two‐way wave‐equation

SEG Technical Program Expanded Abstracts 2011, 2011
We propose an image-domain velocity model building method using the two-way wave equation and extended seismic images. We show that common-image-point gathers can effectively extract velocity information from steep reflections imaged with the two-way wave propagator.
