The seismic reflection method seeks to extract maps of the Earth's sedimentary crust from
transient near-surface recording of echoes, stimulated by explosions or other controlled …

Kirchhoff million is the most popular method of three-dimensional prestack depth migration
because of its flexibility and efficiency. Its effectiveness can become limited, however, when …

Common-image gathers are an important output of prestack depth migration. They provide
information needed for velocity model building and amplitude and phase information for …

Historically, seismic migration has been the practice (science, technology, and craft) of
collapsing diffraction events on unmigrated records to points, thereby moving (“migrating”) …

Complex velocity models characterized by strong lateral variations are certainly a great
motivation, but also a great challenge, for depth imaging. In this context, some unexpected …

Ray-based prestack depth migration fails to image quantitatively complex structures when a
single arrival—for example, the first or the strongest one—is taken into account. In this …

A wave equation‐based poststack depth migration method is proposed to image the Earth's
internal structure using teleseismic receiver functions. By utilizing a frequency wave number …

Strong refraction of waves in the migration velocity model introduces kinematic artifacts—
coherent events not corresponding to actual reflectors—into the image volumes produced by …

Seismic processing and imaging workflows have been refined over many decades to
attenuate aspects of the recorded wavefield which would be improperly mapped into the …
