3D SRME: Acquisition & Processing Solutions

This paper describes the issues and possible solutions involved in the application of 3D data-driven multiple removal in a marine production environment. The optimization of marine data acquisition for 3D Surface related multiple elimination (SRME) is discussed. Recommendations for acquisition are given to create a dense grid of sail lines and streamers needed to predict the full 3D characteristics of the multiples. A processing sequence is discussed to predict and remove 3D multiples for each sail line using only the recorded data around the output streamer. The processing strategy does not rely on any a priori information or model of the subsurface to remove 3D multiples. The application of 3D SRME to a field data set from the Norwegian Sea leads to results that could not be obtained using its 2D equivalent.
