Delineating the Undiscovered Lower Wing of A Miocene Carbonates From Central Luconia Province and Its Potential

The studied field is a carbonate, gas bearing accumulation consisting of Miocene faulted bank carbonates overlain by younger pinnacle reefs. This study aims to assess the prospectivity of an undrilled lower wing by evaluating reservoir quality, gas volumes, and connectivity with the main reef. The workflow includes sedimentology, seismic interpretation, attribute analysis, analogues, and facies modeling. The field shows an open-winged pinnacle with transgressive upward trends, undergoing build-out, build-up, and build-in stages, with wings forming during the build-out. Seismic attributes indicate carbonate progradation from the main reef during low accommodation space periods, with thicker carbonate packages in the northern region. Reservoir architecture analysis considers rock types, porosity, permeability, and water saturation conditioned to depositional facies and seismic inversion products. This comprehensive study provides insights into the potential for further appraisal or infill wells in the lower carbonate wing.
