Using 3-D seismic attributes in Study of the Upper Triassic–stratigraphic setting of the Elward Area in the Syrian Euphrates Graben

Abstract

3D seismic attributes were used in this research, to show the Upper Triassic- stratigraphic setting of the Elward Area in the Syrian Euphrates Graben. 3D seismic attributes were also used to study of the fluvial channel system and the features of its facies, which were formed in the Upper Triassic, along the study area.

The maps of seismic attributes which include volume reflection spectrum (VRS), relative acoustic impedance (RAI) and coherency maps, were used and contributed to understanding the general stratigraphic setting of the study Area. The attribute maps revealed different types of fluvial chnnels. The attribute maps also revealed fluvial features such as point bars, ox-bow lakes and crevasse splays.

The presence of various channels, as indicated in the attribute maps, provided significant information about the paleo-relief and the direction in the Upper Triassic period.
