Geofizicheskiy Zhurnal| Summary: | Various types of hydrocarbon traps associated with intensively developed salt bodies cannot be reliably delineated and then successfully explored by drilling without first obtaining adequate seismic images. This paper shows that such images can only be obtained by a synergic combination of the most advanced options for acquisition system, processing, velocity model and migration as elements of technology as a whole. Currently, such most progressive elements are wide- and full-azimuth acquisition systems, tilted transversely isotropic velocity model, reverse time migration and special processing techniques that enhance the effectiveness of this method. This is substantiated by the actual data examples demonstrated in this paper. |
