Conventional prestack depth migration (PSDM) based on point-source shot data involves a huge number of time-consuming wave extrapolations. Areal-source prestack data generated by a synthesis procedure can provide an alternative migration scheme that

Conventional offset domain prestack migration tends to bring ambiguity and migration artifacts because it smears energy from different angles at the image point. To avoid this, prestack depth migration implementations in angle domain have been invest

The integrated wave equation datuming scheme is an integrated datuming method to implement the wave equation velocity replacement with a one-way extrapolator for overthrust data. The integrated wave equation datuming scheme is accomplished by downwar

An integrated wave-equation datuming scheme improves the imaging quality of seismic data from overthrust areas. It can be regarded as integrated because upward-layer replacement is included. In this scheme, data are downward continued to a nonplanar

Numerical simulation in the frequency-space domain has inherent advantages, such as: it is possible to simulate wave propagation from multiple sources simultaneously; there are no cumulative errors; only the interesting frequencies can be selected; a

Fresnel volume tomography (FVT) offers higher resolution and better accuracy than conventional seismic raypath tomography. A key problem in FVT is the sensitivity kernel. We propose amplitude and traveltime sensitivity kernels expressed directly with

Conventional prestack depth migration (PSDM) based on full prestack data involves many computations for wavefield extrapolation. Areal shot-record technology offers an attractive alternative for efficient PSDM because its synthesis process greatly de

To support amplitude variation with offset (AVO) analysis in complex structure areas, we introduce an amplitude-preserving plane-wave prestack time migration approach based on the double-square-root wave equation in media with little lateral velocity
