Compared with the conventional 3D seismic inversion, the pseudo-acoustic 3D seismic
inversion based on characteristic logs reconstruction greatly improves the ability to
identify internal seismic sub-facies. Several internal sub-facies in each member of the
nearshore subaqueous fan in the lower Es4 Formation have been identified.

The pseudo-acoustic 3D seismic inversion technique based on logs reconstruction
reveals the 3D seismic sedimentological characteristics of nearshore subaqueous fans
including the internal sub-facies structure and various temporospatial evolution stages
in different sub-facies. The distribution of the effective sand-conglomerate reservoirs
can be better quantified by using this method than the conventional 3D seismic
impedance inversion.
