Reverse-time-migration of multiply scattered seismic waves
Multiply scattered waves, including internal multiples, are rarely considered as signal when imaging with seismic waves. Reverse-time-migration techniques accurately handle the propagation of such complex scattered waves, but most of these techniques paradoxically do not fully utilize the illumination and energy of multiply scattered waves because these methods rely on the single-scattering ass...
متن کامل3D angle gathers from reverse time migration
Common-image gathers are an important output of prestack depth migration. They provide information needed for velocity model building and amplitude and phase information for subsurface attribute interpretation. Conventionally, common-image gathers are computed using Kirchhoff migration on commonoffset/azimuth data volumes. When geologic structures are complex and strong contrasts exist in the v...
متن کاملLinearized inverse scattering based on seismic reverse time migration
In this paper we study the linearized inverse problem associated with imaging of reflection seismic data. We introduce an inverse scattering transform derived from reverse time migration (RTM). In the process, the explicit evaluation of the so-called normal operator is avoided, while other differential and pseudodifferential operator factors are introduced. We prove that, under certain conditio...
متن کاملInverse Scattering of Seismic Data in the Reverse Time Migration (rtm) Approach
Abstract. In this paper, we revisit the reverse-time imaging procedure. We discuss an inverse scattering transform derived from reverse-time migration (RTM), and establish its relation with generalized Radon transform inversion. In the process, the explicit evaluation of the so-called normal operator is avoided, at the cost of introducing other pseudodifferential operator factors. Using techniq...
متن کاملSubsurface Imaging with Reverse Vertical Seismic Profiles
A novel imaging process, referred to as vector image isochron (VII) migration, is specifically designed to reduce artifacts caused by arrays with limited apertures. By examining the assumptions behind generalized Radon transform (GRT) migration, a new approach is found which identifies and suppresses array artifacts, based on the array geometry and the migration earth model. The new method work...
