This study aims to illustrate the role of seismic attributes analysis to improve tracing of subtle stratigraphic features, such as shallow fluvial channel systems. The study is carried out in Scarab gas field, located in the WDDM area, which embodies deep marine slope channels. The methodology implemented here is to analyze the available seismic data volume, using the spectral decomposition and root mean square (RMS) attributes, to highlight the occurrence and extension of channel features on the stratigraphic surface of interest and within a certain time interval slice. Below the total depths of the present wells, a new deeper channel is expected to be apparent below channel-2 (below the total depths of wells Dc) and to the west of channel-16 at the time slice 2460 ms (about -2035 m depth).
