AbstractThe East Godavari Sub-basin, located within the Krishna-Godavari (KG) Basin, is a prolific hydrocarbon province shaped by complex deltaic sedimentation and tectonic deformation during the Paleogene-Neogene period. This study employs an integrated seismic attribute approach to evaluate the geometry, facies variation, and continuity of Lower Eocene reservoir sands within a gas-bearing structure. By combining three-dimensional seismic interpretation with well-log correlation, two key pay-sand intervals were delineated with improved structural and stratigraphic clarity. Advanced seismic attributes, notably instantaneous bandwidth and geometric parameters, effectively resolved subaqueous channel systems and identified spatial variations in energy absorption associated with lithological and fluid changes. Areas displaying higher absorption correspond to intervals of greater porosity and fluid content, highlighting potential hydrocarbon-rich zones. Frequent channel migrations driven by variable sediment supply explain the subdued channel-cut signatures in amplitude data. Structural analysis reveals that growth-fault-related roll-over features and shale diapirs provide primary traps, while depositional heterogeneity governs reservoir distribution. This integrated analysis improves understanding of subsurface architecture and reservoir behavior, providing a robust framework for optimizing well placement and guiding hydrocarbon exploration in the East Godavari Sub-basin of the KG Basin.
