Diffraction imaging can lead to high-resolution characterization of small-scale subsurface
structures. A key step of diffraction imaging and tomography is diffraction separation and …

Diffraction imaging aims to emphasize small-scale subsurface heterogeneities, such as
faults, pinch-outs, fracture swarms, channels, etc. and can help seismic reservoir …

To improve the time-domain imaging of poor-quality seismic data, the common-reflection-
surface (CRS) stack method was introduced to simulate zero-offset (ZO) stacked sections …

Various seismic imaging methods are introduced to resolve some of the possible
ambiguities of seismic interpretation in complex structures. Reducing dependency of …

The fault-karst reservoir, which evolved from the deformation and karstification of carbonate
rock, is one of the most important reservoir types in Western China. Along the deep-seated …

Diffraction imaging aims to emphasize small subsurface objects, such as faults, fracture
swarms, and channels. Similar to classical reflection imaging, velocity analysis is crucially …

Diffracted seismic waves may be used to help identify and track geologically heterogeneous
bodies or zones. However, the energy of diffracted waves is weaker than that of reflections …

We have used least-squares migration to emphasize edge diffractions. The inverted forward-
modeling operator is the chain of three operators: Kirchhoff modeling, azimuthal plane-wave …

Diffraction imaging is a useful tool for seismic reservoir characterization because it can
provide additional information about small-scale heterogeneities. Diffractions and reflections …

Diffracted waves contain a great deal of valuable information about small-scale subsurface
structure such as faults, pinch-outs, karsts, and fractures, which are closely related to …
