インドネシア西ジャワのカンダンハウル・ガンタール高を対象に、上部バトゥラジャ層のCO₂貯留層としての実現可能性を文献・既存データに基づき予備評価した。深度1600〜1900m、孔隙率20〜25%、良好な連続性とシール層が確認され、既存の油ガスインフラと近接CO₂源も活用可能である。貯留容量は大規模CCS比で小さいが、パイロット規模のCCS/CCUS候補地として有望と結論づけた。
English
This literature-based preliminary study assesses the Upper Baturaja Interval in the Kandanghaur-Gantar High, West Java, as a potential CO₂ storage reservoir. The interval lies at 1600–1900 m depth with 20–25% porosity, good lateral continuity, and an effective sealing system, supported by existing oil and gas infrastructure and nearby CO₂ sources. Although storage capacity is modest, the site is a viable candidate for pilot-scale CCS/CCUS development.

📄 Abstract（原文）
Carbon Capture and Storage (CCS) is a major approach for reducing carbon emissions, particularly in areas with intensive industrial and hydrocarbon production activities. Therefore, this study aims to evaluate feasibility of Upper Baturaja Interval in Kandanghaur-Gantar High (KGH), Jatibarang Sub-Basin, West Java, as a potential field-scale carbon dioxide (CO₂) storage area. The designed preliminary assessment was based on available literature and field data to provide an initial technical evaluation of the area at a maturity level suitable for pre-feasibility stage development. A qualitative method was adopted using standard CO₂ storage screening criteria, including reservoir depth, petrophysical properties, thickness and lateral continuity, caprock integrity, storage capacity, and proximity to emission sources. The results showed that Upper Baturaja interval occurred at depths of approximately 1600–1900 m, with porosity ranging from 20% to 25%. This interval was dominated by secondary porosity, characterized by ideal field-scale continuity. The presence of hydrocarbon accumulations, including the absence of significant structural disturbances above the target interval, suggested an effective sealing system. Based on an implementation perspective, the study area benefitted from neighboring CO₂ sources derived from associated gas production alongside existing oil and gas infrastructure. The estimated storage capacity was also relatively modest compared to large-scale CCS projects. The combination of favorable geological and operational factors suggested KGH was a viable candidate for pilot-scale or early-stage CCS/CCUS development. Future studies should include static and dynamic modelling, injection simulation, and risk assessment to quantitatively validate storage performance.
