Abstract

Recently, first processing results of 2D dual-sensor towed streamer data have been presented. A dual sensor streamer is capable of recording not only the pressure field but additionally the vertical component of the particle velocity field. A proper combination of both records yields the separation of up- and downgoing wavefields. In this paper, we review the theory behind the dual-sensor streamer specific processing steps for 2D and describe their extension to the 3D case. We highlight 3D specific problems related to typical marine acquisition geometries and propose a 3D data processing solution which addresses these problems. Part of the proposed processing scheme is a new method designed to deal with spatially aliased energy in a local way. We demonstrate this new technique using a field data example.
