Importance of Pressure Data in Aiding TD Call of a Dual GWC Discovery in Central Luconia

Abstract Conventional drilling practices in Central Luconia assume vertically and laterally connected carbonate porosity, resulting in a single pressure system and a single gas-water contact (GWC). This assumption was challenged during the P Field exploration campaign, where Well P2 encountered an unexpected shallow water contact inconsistent with regional aquifer trends. Real-time pressure analysis, combined with comparison to adjacent fields, revealed that the early contact represented a perched GWC caused by low-permeability, cemented talus facies at the pinnacle flank. Continued drilling confirmed a deeper, true GWC aligned with regional aquifer pressures and hydrocarbon column expectations. This study presents a rare dual-GWC system in Central Luconia and demonstrates the critical role of pressure integration in preventing premature TD calls, ensuring accurate volumetric estimation, and enabling a robust development concept.
