Carbon dioxides capture and storage (CCS), a technology that captures and stably stores carbon dioxide deep underground for long periods of time, is considered to play an important role in achieving decarbonization. To select suitable CO₂ storage sites for CCS, subsurface data such as seismic and well data are often used for site screening and selection but evaluating wide region using subsurface data takes time. Furthermore, since availability of subsurface data is normally not uniform, it is sometimes difficult to obtain evaluation with uniform criteria and data for the whole area of interest.

Therefore, to enable the screening study over a broad area using uniform criteria, JOGMEC have conducted the assessment for CCS screening in Southeast Asia using regional geological database (Neftex by Halliburton). A regional scale assessment was conducted for the entire Southeast Asia region as Phase 1 and a basin scale assessment as Phase 2. In Phase 1, basins of Southeast Asia were ranked based on conditions of suitability. Considering Phase 1 result and the location of CO₂ emission sources, twenty-three target formations/intervals in thirteen sedimentary basins were selected for Phase 2. The results of Phase 2 were summarized as a fairway map showing the geological suitability of CCS and CO₂ storage capacity estimated based on simple volumetric method for each target formation/interval. The results of Phase 1 are consistent with the location of planned CCS & CCUS projects in Southeast Asia, indicating the potential utility of this methodology for site screening at the regional scale. Phase 2 methodology could be used to identify CCS suitable areas by formation and to calculate rough estimation of the storage volume. The methodology used in this study allows for consistent site screening for CCS over a wide area.

This conference aims to share the JOGMEC’s experience on the CCS screening methodology and the assessment results in the Southeast Asia.
