Azimuthally Anisotropic 3D Velocity Continuation
We extend time-domain velocity continuation to the zero-offset 3D azimuthally anisotropic case. Velocity continuation describes how a seismic image changes given a change in migration velocity.

| description | We extend time-domain velocity continuation to the zero-offset 3D azimuthally anisotropic
case. Velocity continuation describes how a seismic image changes given a change in migration
velocity. This description turns out to be of a wave propagation process, in which images
change along a velocity axis. In the anisotropic case, the velocity model is multiparameter.
Therefore, anisotropic image propagation is multidimensional. We use a three-parameter
slowness model, which is related to azimuthal variations in velocity, as well as their principal
directions. This information is useful for fracture and reservoir characterization from
seismic data. We provide synthetic diffraction imaging examples to illustrate the concept
and potential applications of azimuthal velocity continuation and to analyze the impulse
response of the 3D velocity continuation operator. |
