Abstract

Summary

We present broadband processing results for a dataset acquired north-west of Shetland. Attenuation of multiples was challenging because of the presence of a hard, variable depth water bottom and complex geology. Streamers were towed deep (20m to 30m) during acquisition, with a mild slant of 1m per km of offset, and with a maximum offset of 10km. This acquisition configuration allowed the use of multiple attenuation methods designed for conventional data, while at the same time allowing broadband postmigration de-ghosting with an overall processing turnaround time comparable to that for conventional processing projects.
