Paper Summary

A four-part series of short webinars that addresses fundamental issues necessary to achieve high resolution seismic imaging with towed streamer acquisition and imaging is available at the PGS Webinar Library. Suitable for anyone with a basic knowledge of reflection seismic principles, the series begins by establishing the key factors during towed streamer acquisition that influence the temporal frequency content available for seismic imaging. After identifying the best-practice spatial sampling limits of wide tow multi-source shooting with long GeoStreamer spreads I then highlight how even shorter spatial sampling intervals (i.e., high spatial frequencies) are required to exploit kilohertz frequencies produced by Boomer and Sparker source concepts used for 3D UHR (ultra-high-resolution) towed streamer surveys. After identifying key acquisition and imaging considerations necessary to optimize 3D UHR seismic projects I conclude with several use cases and example survey designs.
