On the separation of simultaneous-source data by inversion

Examples

Using 2D models extracted from the 3D SEAM geophysical model (Figure 1), we consider data separation for three possible simultaneous-source applications. The grids in both models have been modified. All data were modeled with a 2D Acoustic finite-difference algorithm. In each example, we use the different formulations to solve the separation problem described above. All sparse inversion examples are generated using a hybrid solver (Li et al., 2010).
