متن کاملMigration velocity analysis for nonlinear reverse-time migration
Nonlinear reverse-time migration is a modified reverse-time migration that accounts for the nonlinear relation between seismic data and model in order to image multiply scattered waves including multiples. The illumination of multiply scattered waves yields a representation of the Earth’s subsurface that is more sensitive to model parameters, which allows for advanced seismic interpretation. Th...
متن کاملReverse Time Migration = Generalized Diffraction Stack Migration
The standard reverse-time migration (RTM) algorithm is usually described as zero-lag correlation of the backprojected data with the source wavefield. The data are back-projected by a finite-difference algorithm, where each trace acts as a source-time history of a point source at the geophone location. This is a simple and easily understood migration method, but appears inflexible to improvement...
