Converted-Wave Moveout Analysis in Layered Anisotropic Media - a Case Study

L-27 CONVERTED-WAVE MOVEOUT ANALYSIS IN LAYERED ANISOTROPIC MEDIA – A CASE STUDY JERRY YUAN 1 2 XIANG-YANG LI 2 and ANTON ZIOLKOWSKI 3 Summary 1 We present a new and improved non-hyperbolic moveout equation for converted waves (C-waves) propagating in layered media with vertical transverse isotropy (VTI) and demonstrate its application through a case study. The new equation is accurate up to offset-depth ratio x/z=2.0 forming the basis for parameter estimation. A new parameter χ is introduced to quantify the anisotropic effect on C-wave reflection moveout. With a priori knowledge of the vertical velocity ratio and the P-wave stacking velocity
