Abstract
Applied to multicoverage data, the Common-Reflection-Surface (CRS) method obtains, besides a clear stacked section, also a number of traveltime parameters or attributes defined at each point of that section. The CRS parameters provide useful information for a variety of seismic processing purposes. We consider the use of CRS attributes in multiple identification and attenuation. In the 2D situation, the CRS method produces three parameters associated with the resulting simulated (stacked) zero-offset (ZO) section. We propose and discuss simple algorithms designed to identify and, as a next stage, attenuate or eliminate multiples. First experiments show that these algorithms have the potential of favorably replace well-established multiple suppression methods.
