IMAGING THE AFEN SLIDE FROM COMMERCIAL 3D SEISMIC -METHODOLOGY AND COMPARISONS WITH HIGH-RESOLUTION DATA.

摘要

The Afen Slide lies in deep waters within the Faroe Shetland Channel (FSC) and was first recognised on TOBI data in 1996. Subsequently, it was observed on a 3D seismic survey that had been acquired in 1995. This paper presents the latest image of the slide generated from 3D seismic and the methodology used in attenuation of geophysical artefacts. It is demonstrated that 3D seismic has the potential to produce highly detailed images of seafloor features in deep-water areas comparable with swath or TOBI.
