Title:
Anisotropy signature in extended images from reverse-time migration
Authors:
Sava, Paul; Alkhalifah, Tariq Ali ( 0000-0002-9363-9799 )
Abstract:
Reverse-time migration can accurately image complex geologic structures in anisotropic media. Extended images at selected locations in the earth, i.e. at common-image-point gathers (CIPs), carry enough information to characterize the angle-dependent illumination and to provide measurements for migration velocity analysis. Furthermore, inaccurate anisotropy leaves a distinctive signature in CIPs, which can be used to evaluate anisotropy through techniques similar to the ones used in conventional wavefield tomography.
