Abstract

I present a general methodology for computing and analyzing Angle-Domain Common Image Gathers (ADCIGs) in conjunction with anisotropic<br>wavefield-continuation migration. I demonstrate that the aperture angles estimated by transforming prestack images using slant stacks along the <br>subsurface-offset axisi are good approximations of the phase aperture angles.<br>I analyze the perturbation in the angle-domain image caused by perturbations in anisotropic parameters, and present a general expression for computing Residual Moveout (RMO) curves. <br>Several synthetic-data and real-data examples demonstrate the accuracy of the RMO function predicted by my kinematic analysis.
