Subsalt imaging with internal multiples
نویسنده
چکیده
If singly scattered seismic waves illuminate the entirety of a subsurface structure of interest, standard methods can be applied to image it. In many cases, subsalt imaging for example, a combination of restricted acquisition geometry and imperfect velocity models results in regions of the model that are not illuminated with singly scattered waves. We present an approach to use multiply scattered waves to illuminate such structures, and illustrate the method by creating images of the base of salt with an erroneous velocity model. This method builds upon past work in which methods to predict artifacts in imaging from multiply scattered waves have been developed and shares similarities with current techniques of imaging with surface-related multiples.

Target-oriented interferometry: Imaging internal multiples from subsalt VSP data
Seismic interferometry has become a technology of growing interest for imaging borehole seismic data. We demonstrate that interferometry of internal multiples can be used to image targets above a borehole receiver array. By “internal multiples” we refer to all types of waves that scatter multiple times inside the model. These include, for instance, interbed, intra-salt and water-bottom multiple...

Technology advances, such as WAZ/FAZ acquisition, reverse time migration (RTM) and iterative salt imaging in model building, have greatly improved subsalt image quality. However subsalt imaging under complex salt overburden is still challenging. The fundamental issue lies with the imperfect illumination from limited acquisition. In the poor illumination zones, the migration artifacts and cohere...
