Application of Anisotropic Velocity Modeling and Pre-Stack Depth Migration in the Deepwater Gulf of Mexico

C008 Application of Anisotropic Velocity Modeling and Pre-Stack Depth Migration in the Deepwater Gulf of Mexico S.L. Neal* (Chevron) SUMMARY Seismic imaging in the Deepwater Gulf of Mexico (GoM) has been and continues to be a challenge for all phases of exploration and development. Although the presence of an anisotropic velocity structure has long been recognized it is only occasionally analyzed rigorously or integrated into seismic imaging. A significant challenge posed in the shift to anisotropic imaging is the development of stable and geologically robust workflows. Our anisotropic Pre-Stack Depth Migration (PSDM) workflow consists of three key steps: building the
