Seismic geomorphology has recently become an important tool and a new topic of discussion for analyzing deposition environments, especially deltaic depositional environments. However, the application of 3D seismic geomorphology to identify and reconstruct the history of deposition is still limited to tectonically stable settings and specific environments, especially in shallow intervals. Therefore, research using these tools and methods is still infrequent.Knowing subsurface conditions, such as the geometry and shape of a depositional environment, can assist various studies in determining the hydrocarbon reservoir conditions in a location before drilling activities commence. Hence, one or more methods are needed to aid in subsurface architectural studies. Some methods used in this research include seismic geomorphology, seismic stratigraphy, Spectral Decomposition, and seismic attribute analysis such as Instantaneous Phase and Root Mean Square (RMS). The F3 field was chosen as the research area, located in the North Sea sector of the Netherlands, with significant shallow gas reserves that are commercially viable. This field has been extensively explored in the oil industry, providing extensive 2D and 3D seismic information. The study focused on searching for channel deposits and calculating channel geometry to understand the architecture and evolution of the channels in the research area.Several channel deposits were found on Horizon MFS 4 with a fixed river system type. Additionally, deltaic deposition patterns were identified on Horizon FS 8. The reservoir characteristics in the research area are generally dominated by the presence of sandstone, siltstone, and mudstone resulting from strong marine surface activities. Suspected normal faults were also found, serving as hydrocarbon migration pathways, including shallow gas in the research area.
