Visualization and extraction of 3D sand units from seismic data are critical for improving
reservoir understanding, detecting anomalies, and defining facies. Stratigraphic features of the
reservoir can be identified using seismic frequency based attributes; spectral decomposition,
RGB blending and geobody extraction. A geologic feature can then be better delineated and
extracted as a geobody. Once extracted, the further 3D static reservoir model can be constructed
for any future reservoir characterization and development.
The present study is an attempt to show at what extent the frequency based attributes success
to define the lateral and vertical distributions of the sand bodies and its internal units without any
conventional seismic interpretation. The study was performed on the sand reservoir units within
Mit Ghamr Formation, Taurt Field.
The application of these frequency attributes was successfully revealed the geometrical
distribution of the sand units; S10, S20 and S30 in different directions.
