| ABSTRACT
For a stratigraphic sequence
in the Tertiary section of the North Sea Central Graben, seismic attributes
have enhanced the 3-D seismic interpretation by imaging a deep-water channel
system. Although sands in the channels are seismically invisible, chalk
debris flows within the channels appear as high-amplitude reflections,
or "bright spots" in the attributes, that mark the axes of the system.
Our interpretation of the depositional units initially suggested that the
patchy but slightly dendritic pattern of bright spots was part of a distributary
channel system. Forward modeling of the seismic attributes indicated that
the bright spots do not indicate the presence of hydrocarbons and that
individual oil sands cannot be located with the seismic data. Instead,
the channels that are prone to sand are delineated by the chalk debris
flows that are visible on the seismic attribute maps.
