Abstract
The article is dedicated to the wave field transformation approach and its different practical applications. Described approach is based on the layered depth-velocity model usage. Wave field transformation is computed layer-by-layer. The transformation methods include: wave field “redatuming” – data calculation from current level of sources and receivers location to the deeper level; a migration algorithm – an analogue of reverse time migration algorithm (RTM); transformation of wave field to the upper level; multiple waves modeling and modeling of direct and reflected waves.
