Paper Summary
Existing 5D methods fall into two categories, surface-consistent and subsurface-consistent. In the first, seismic traces are interpolated or regularized into a grid of source and receiver lines. In the second, the target grid is defined by CDP bins and either offset vectors or offset/azimuth pairs. Each of these approaches has advantages and disadvantages. In this study, the authors introduce a novel 5D approach, called surface-line 5D, which bridges these two categories and incorporates certain advantages of each.
