Box 5031 2600 GA Delft The Netherlands 2 Shell International E&P Summary The near subsurface can give rise to variations in travel times and amplitudes of upcoming reflections and strong scattered surface waves obscuring reflections. Near-receiver scattered noise can be considered a combination of these problems. On an intra-array scale near-receiver scattered noise can be tracked along a few traces. This implies that it can be suppressed using a deterministic method. We have developed such a method;
