SUMMARY We propose a novel approach for suppression of multiples using the t-x-p domain, where p is the local slope of seismic events, and discuss the merits and demerits of this approach. We take CMP gathers and transform them from the original t-x space to the extended t-x-p space. We pick the velocities for primary reflections and form filters as functions that go to unity for primaries and zero for multiples. Multiplying the gather in the extended space by such filters and stacking along the p axis produces a gather with multiples suppressed. Synthetic and real data examples demonstrate the potential of the proposed approach.
