Abstract

SRME-based multiple attenuation methods are often ineffective when applied to OBS/OBC data due to the acute disparity in the shot and receiver distribution and the difference in source and receiver datum in ocean bottom acquisition geometries. Wavefield extrapolation based multiple attenuation schemes take advantage of the fine sampling of the source wavefield, and are insusceptible to poor receiver sampling or datum differences. The technique models the multiples in the common receiver domain by sending the recorded source wavefield into the subsurface and simulating the backscattered wavefield as first order multiples at the source locations. Synthetic examples demonstrate the effectiveness of the method. This technique, in combination with PZ summation to address receiver-side ghosts, provides an effective multiple attenuation flow for OBC/OBS data.
