Abstract

Driven, primarily, by the desire to image sub salt targets in the GOM, the industry has made significant improvements in towed streamer acquisition technology, to improve imaging through complex over-burdens. This paper will review a new towed streamer technique which makes a full azimuth seismic measurement with ultra-long offsets (14,000m), which was designed to mitigate imaging limitations of the commonly used WAZ designs in the US GOM. The final design was based on a very intensive modeling study, on real and synthetic models, using a finite difference modeling approach.
