Surface-related multiples typically correspond to the largest component of multiple energy on marine seismic data because the surface is an almost perfect reflector with a reflectivity close to unity and, thus, their elimination is a major goal of seismic processing. Recent work has shown surface-related multiple elimination (SRME) to be effective in attenuating surface-related multiples, particularly in complex geology which may include diffracting features.

Figure 1 shows the basic idea behind SRME. A surface-related multiple is recorded at receiver Xr due to a shot at location Xs. The event is a surface-related multiple because it undergoes at...
