On High-Resolution Mapping of Subsurface Sedimentary Facies and Reservoirs Using Seismic Sedimentology

This investigation presents the current status of seismic sedimentology, as applied to high-resolution (<5m) mapping of sedimentary facies and hydrocarbon reservoirs in the subsurface. Seismic sedimentology involves the integrated study of seismic lithology and seismic geomorphology. High-resolution lithology, thickness, and geobody geometry mapping can be achieved by focusing on spatial resolution, data quality, attribute selection, seismic modeling, and application of machine learning techniques. As their geophysical counterparts, the interpreters with geologic background can do as good in seismic sedimentology.
