“…In order to delineate the hydrocarbon potential of the Paleocene carbonate reservoir at the Balkassar area multi-attribute analysis techniques were utilized. The multi-attribute analysis fundamentally incorporates the analysis of different seismic attributes simultaneously or in combination [10]. The workflow included the preparation of time and depth contour maps for subsurface structure and stratigraphic interpretation, and seismic attributes analysis using 3D seismic data to evaluate the possible reservoir characteristics of the Paleocene carbonate reservoir at the Balkassar area.…”

The structural and seismic properties of the Paleocene carbonate reservoir are re-evaluated, using 3D seismic data multi-attributes, to improve reservoir prediction accuracy rarely documented earlier. This study highlights a number of relevant post-stack seismic attributes for understanding the structural setup and seismic properties of a carbonate reservoir. The structural analysis was carried out using seismic interpretation, combined with multi-attribute analysis for prospect actualization and generation of a 3D structural model to determine the structural aspect. The structural interpretation reveals the presence of faults and an asymmetrical anticlinal structure demonstrating a four-way closure, confirming compressional tectonics. The high amplitude anomaly (-6 to 12) combined with the RMS attribute (23 to 32) suggests bright spots in the Paleocene carbonate reservoir and gas saturated zone, the variance attribute (0.05 to 0.03) highlights the presence of two major faults, and the lower instantaneous frequency demonstrates the presence of hydrocarbons. The attribute results indicate that the Lockhart Limestone possesses good reservoir potential as revealed by DHI (bright spot), gas saturated zone and a trapping mechanism supported by four-way structure closure in the region and can help to understand analogous carbonate reservoirs in similar geological settings around the world.
