Efficient wavefield separation by reformulation of two-way wave-equation depth-extrapolation scheme

Geophysics, 2022
ABSTRACT In two-way wave-equation depth migration by either time extrapolation or depth extrapolation, an efficient wavefield separation scheme (to separate two-way wavefields into their one-way counterparts: down- and upgoing waves) is typically required for high-quality imaging.

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.

Two-way wave equation-based depth migration using one-way propagators on a bilayer sensor seismic acquisition system

GEOPHYSICS, 2018
Conventional migration uses the seismic data set recorded at a given depth as one initial condition from which to implement wavefield extrapolation in the depth domain. In using only one initial condition to solve the second-order acoustic wave equation, some approximations are used, resulting in the limitation of imaging angles and inaccurate imaging
