P109 CONVERTED-WAVE IMAGING IN INHOMOGENEOUS ANISOTROPIC MEDIA – PART I – PARAMETER ESTIMATION Summary 1 In transversely isotropic media with a vertical symmetry axis (VTI) the converted-wave (Cwave) moveout over middle-to-long offset range is determined by four parameters. These are the C-wave stacking velocity VC2 vertical and effective velocity ratios γ0 and γeff and anisotropic parameter χeff. Detailed numerical analysis is performed to evaluate the sensitivity and error propagation during C-wave moveout inversion. The results show that the two velocity ratios cannot be resolved by semblance analysis with sufficient resolution and accuracy even for exact inputs of VC2 and χeff.
