Abstract

Abstract

A high-resolution velocity model is required in order to produce an accurate image of the subsurface in any complex geological setting. In shallow water environments, diving wave and refraction-based FWI has been widely used to resolve small-scale features. However, the depth that can be updated is limited by the deepest turning point of the diving waves. In a deep-water environment the use of diving waves and refractions is generally limited by the lack of ultra-far offsets required to record a sufficient amount of refracted energy. Furthermore, diving wave and refraction-based FWI assumes a medium with increasing interval velocities at all depths of interest.
