Migration moveout analysis and depth focusing

WebDetails of the P- and PSv-wave processing of this dataset through anisotropic prestack time migration were previously described (Johns et al., 2006) in which it was demonstrated there existed a qualitative correlation between derived parameters and attributes from P and Sv anisotropic migration velocities and known regional geology. WebTwo methods of depth imaging are developed, Kirchhoff-approximate migration and Kirchhoff-approximate migration/inversion. Both rely on the Kirchhoff approximation at the reflecting surface. The second method, determined from Born-approximate inversion, provides exact expressions for constant-wavespeed common-offset migration/inversion …
