Unlocking the Diagenetic Evolution and Its Implications for Development Strategy: Case Study of Prabumenang Field, Indonesia

The diagenetic evolution of carbonate reservoirs are critical factor in optimizing reservoir characterization for a future play in hydrocarbon development. The development of the carbonate reservoir in Prabumenang Field, Pagar Dewa Development Project (PGDP), South Sumatra Basin had a complex geological process that is related to the diagenesis process. Reservoir characterization was an important aspect in determining the distribution of high porosity rock facies that can flow hydrocarbon. This study presents a comprehensive analysis of the Prabumenang Gas Field in South Sumatera Basin focusing well on well property and production history analysis. A Qualitative Interpretation based on stratigraphic deposition marker (Maximum Flooding Surface Flattening Correlation) shows the pattern of diagenesis carbonate rock distribution by a near perfect interpretation. The significances of this study extend beyond the special case study, highlighting the advanced integrated study by characterizing the high heterogeneity reservoir in further development planning in diagenesis play reservoir. The success story presented here underscores the necessity of proactive measures in well placement and field development to maximize recovery from diagenetically complex reservoirs. This study serves as a roadmap for future endeavors in optimizing hydrocarbon production from carbonate reservoirs, emphasizing the significance of a comprehensive understanding of diagenetic evolution and distribution.
