Localization of fractured areas is of primary interest in the study of oil and gas geology in
carbonate environments. Hydrocarbon reservoirs in these environments are embedded …

With a finite recording aperture, a limited source spectrum and unbalanced illumination,
traditional imaging methods are insufficient to generate satisfactory depth profiles with high …

We develop the true‐amplitude prestack migration of multicomponent data based on the use
of elastic Gaussian beams for walkaway vertical seismic profile (VSP) acquisition systems. It …

Gaussian-beam migration (GBM) is flexible and adaptable for imaging geologically
complicated areas. It avoids some limitations, such as amplitude singularity in caustic zones …

An approach for true-amplitude seismic beam imaging of multicomponent seismic data in 2-
D anisotropic elastic media is presented and discussed. Here, the recovered true-amplitude …

Abstract Interpretation of seismic responses from subsurface fault zones is hampered by the
fact that the geologic structure and property distributions of fault zones can generally not be …

An overview of two types of beam solutions is presented, Gaussian beams and Bessel
beams. Gaussian beams are examples of non-localized or diffracting beam solutions, and …

Elastic-wave migration is a desirable technique because it can image the structure of the
earth more accurately. We develop a new elastic Gaussian beam migration method with 3D …

Although the pseudoacoustic wave equation has good accuracy in characterizing
anisotropic wave propagation and obtaining interpretable seismic images, a high-precision …

In anisotropic media, the compressional wave scattering phenomena is governed by several
parameters and can be simulated using a good kinematic approximation. How to retrieve …
