Seal assessment is a one of key component in ensuring the long-term containment of injected CO?, a fundamental requirement for the success of carbon capture and storage (CCS) projects. In Indonesia, conducting accurate seal assessments remains a major challenge due to the limited availability of caprock core data. To address this issue, the study introduces a new creation termed as Caprock Quality Index (CQI), as a practical screening tool that combines displacement pressure and caprock thickness as key parameters. Displacement pressure is estimated using an empirical equation, thereby reducing the dependence on laboratory-based measurements. The CQI analysis identifies the Banggai Basin and Salawati Basin, as areas with high sealing potential, indicating strong suitability for CO? storage. This study represents a significant advancement in seal assessment practices in Indonesia and contributes to the development of a more efficient, data-driven framework for future CCS planning and implementation.
