Subsalt illumination study using physically modeled data
article
Despite the widespread use of numerical modeling, there is still room for physical modeling today for many reasons. E.g., physical modeling is based on real wave propagation whereas numerical modeling is based on algorithms which are by necessity simplified and discretized versions of the 'real world'. Furthermore, a numerically modeled, full-size, wide-band, 3-D, elastic data set of tens of millions of traces is simply not yet affordable. Physically modeled data has been acquired for subsalt illumination studies. In particular the data due to sources 'everywhere' at the surface, recorded by a permanent detector inside the model at a subsalt location, is used to determine subsalt illumination. From such a one-way data set, any realistic acquisition configuration can be simulated and its subsalt illumination properties can be obtained.
