Abstract
The method used to build an anisotropic model for TTI migration is described. The method includes calibrating seismic depth to well depths, estimation of the tilted axis of symmetry of the anisotropy, iterative depth migration and tomography, and salt horizon interpretation. Cycle time is reduced by using a fast 3D, wide azimuth, beam, prestack depth migration. Results are shown on a wide azimuth marine survey in the deep water Gulf of Mexico.
