Abstract
In seismic data, random noise can affect the continuity and identification of reflectors. In Common Reflection Surface (CRS) stacked data, part of this noise results from fluctuations and non-physical values of the estimated CRS parameters. This paper presents the result of a method to overcome this problem based on smoothing CRS parameters through the application of local statistics in small windows aligned with reflection events. Smoothing CRS parameters on a real marine data resulted in an increase of S/N ratio, with consequent highlight and greater continuity of the reflections.
