A-44 Imaging under complex salt bodies with 3-D prestack finite difference depth migration Summary 1 We present an implicit finite difference depth migration (IFDM) system. Conventional aspects of IFDM are combined to produce a highly accurate downward continuation process. Appropriate imaging and aperture conditions are employed in a shot migration scheme to generate migrated image gathers in the shot-receiver offset domain. A highly efficient parallel implementation has been achieved without sacrificing accuracy. Results are obtained from both standard and in-house datasets from the SEG/EAGE 3-D Salt Model. These results along with real data examples demonstrate the high-quality sub-salt images obtainable
