Simultaneous sources: A controlled experiment on different source configurations
Peter Aaron, Roald van Borselen, Eivind Frømyr · 2009
The simultaneous firing of marine sources can provide a significant uplift in terms of acquisition efficiency. However, the seismic interference resulting from one or more “other” sources needs to be well understood and the appropriate processing techniques need to be investigated. This paper uses the well known BP Wide-Azimuth Towed Streamer (WATS) synthetic dataset to carry out a controlled investigation into the effect of additional noise in 3D surface-related multiple elimination (SRME), depth migration and source separation. Two different simultaneous source configurations are considered: a front and tail and a side by side survey design. Results show that the front/tail configuration gives naturally cleaner results after 3D SRME and migration, but some source separation should always be applied; 3D SRME or migration alone isn't enough to suppress the additional noise.
