Broadband for Everyone - Increasing Notch Diversity Using Variable Streamer Profiles

This paper presents a case-study across the 2D benchmark line on the Haugaland High in the North Sea. The aim was to test various cable depth profiles, using a hydrophone only cable, to better understand the impact of notch diversity on the final deghosted image. A total of 11 passes with different configurations were tested, all using the same conventional source. The data were then processed with their appropriate deghosting algorithms and results compared. Amongst the profiles tested – one new novel sinusoid snake streamer test showed excellent notch diversity and compares well to other more common slanted profiles.
