Paper Summary
New survey design solutions for marine towed streamer acquisition were recently introduced by Widmaier et al. (2019). One of the key technical elements was the concept of wide-tow multi-sources, i.e., the distribution of multiple sources along the front of a streamer spread. All the wide-tow source case studies acquired in recent years have made use of uniform multi-source and multi-streamer spreads (i.e., regular streamer and source separations), thus following the same industry standards as in marine seismic surveys with narrow source configurations. However, uniform configurations may not always be feasible or optimal due to operational or geophysical constraints. In this article, we revisit the basics of the wide-tow multi-source method and make the step from a uniform to a non-uniform design. The first seismic survey using this novel method is currently being acquired in a challenging area offshore Malaysia.
