One major cause of elastic wave attenuation in heterogeneous porous media is wave-
induced flow of the pore fluid between heterogeneities of various scales. It is believed that …

Prestack depth migration is the most glamorous step of seismic processing because it
transforms mere data into an image, and that image is considered to be an accurate …

Traditionally, the Marchenko equation forms a basis for 1D inverse scattering problems. A
3D extension of the Marchenko equation enables the retrieval of the Green's response to a …

Migration in the angle domain creates seismic images for different reflection angles. We
present a method for computing angle-domain common-image gathers from seismic images …

We analyze the kinematic properties of offset-domain common image gathers (CIGs) and
angle-domain CIGS (ADCIGs) computed by wavefield-continuation migration. Our results …

In the past decade, 3D reflection seismology has replaced 2D seismology almost entirely in
the seismic industry. Recording 3D surveys has become the norm instead of the exception …

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 …

Seismic imaging based on single-scattering approximation is in the analysis of the match
between the source and receiver wavefields at every image location. Wavefields at depth …

Prestack depth migration of shot profiles by downward continuation is a practical imaging
algorithm that is especially cost-effective for sparse-shot wide-azimuth geometries. The …

We present an acoustic migration/inversion algorithm that uses extended double-square-
root wave-equation migration and modeling operators to minimize a constrained least …
