C022 TTI Wave Eequation Migration Using Phase-Shift Plus Interpolation R.A. Bale* (CGGVeritas) S.H. Gray (CGGVeritas) & M.G. Kirtland Grech (CGGVeritas) SUMMARY We describe a PSPI method for wave-equation migration in TTI media. To apply the PSPI methodology for anisotropy we generate reference operators based upon phase error criteria with respect to the symmetry axis direction and exploit correlations between parameters. The method is demonstrated on an elastic synthetic dataset generated over a thrust-belt setting as found in the Canadian Foothills.
