A commercial low-rank coal SNG (substitute natural gas) plant is being planned to build in Pendopo, South Sumatra. However, the CO2 produced is not allowed to be vented and should be managed properly. One approach to manage this anthropogenic CO2 emission is through the utilization for CO2 EOR (enhanced oil recovery) or CO2 sequestration. This workaims to investigate the possibility of application and the readiness carbon capture utilization and sequestration (CCUS) for CO2 management of South Sumatera SNG Plant. It presents technical ranking of suitable reservoirs, injection profiles determination, cluster principle of oil fields that can accommodate the amount of CO2 supplied for a number of years, and planning and realization of trunk pipelines and the possibility to reuse the major part of the present infrastructure. The results show the A1 oil field has the highest rank in the sink scoring indicating that this field has highest suitability for CO2 EOR application and CO2 sequestration. Three clusters are formed, north, southeast and west cluster as the basis to establish pipelines network development. The largest CO2 storage potential is in southeast cluster, 27 MtCO2 and the injection strategy developed is successful to manage CO2 supply from SNG Plant.

Implementation of co2 capture and geological storage technology at the scale needed To achieve a significant and meaningful reduction in co2 emissions requires knowledge of The available co2 storage capacity. Various geological formations located across many Islands in indonesia appear to be potential to store the anthropogenic co2, particularly in Depleted oil and gas reservoir. These depleted oil and gas reservoirs are appropriate Candidates for co2 storage. However, the capacity of this geological formation has not Been estimated yet. The objective of this study is to estimate the storage capacity of depleted Oil and gas reservoirs in indonesia using the methodology, developed by carbon Sequestration leadership forum (cslf). Screening result from our databases showed there Were 103 depleted oil and gas fields were considered depleted from their np/ult ratio (hydrocarbon cumulative production over ultimate recovery) which were 55%. However, Only 48 fields had complete data to estimate. We used the methodology that was Initially developed by cslf but then it had been simplified by poulsen et al. We considered This methodology as the most convenient to use in this country scale of assessment despite Of any simplification had been made. Estimation result showed riau and south sumatra Region have large storage capacities which are around 229 and 144 mtco2 respectively. The estimates of co2 storage capacity reflects the actual capacity that was based on data Availability during the assessment. The potential storage capacity might change as data Becoming more available. Hence, the storage capacity map resulted from this study is not Conclusive estimation. However, this study indicates that indonesia has huge potential of Co2 storage in depleted oil and gas reservoirs.

The various possible strategies to combat global warming are explored within a wideranging of efforts. Practical solutions will need to stop or even reverse the build-up of CO2 in the environment by using existing technology that has not been integrated, carbon dioxide capture and storage (CCS) (Hansson, 2008). The main objectives of this study are to develop criteria for sedimentary basins ranking system in terms of their suitability for CO2 storage and estimate the storage capacity available. We adapt the method developed by Bachu (2003) to the Indonesia geological characteristics. Once the criteria has been developed and the basins ranked based on their suitability, oil and gas fields located within these basins were estimated their potential storage capacity using the methodology developed by Carbon Sequestration Leadership Forum (CSLF). From 60 identified sedimentary basins, Kutei, Tarakan and South Sumatera basins are respectively positioned in top three of the ranking system. Well known geological structure, adequate data, relatively stable geological structure and established infrastructures are the main factors make these basins have higher suitability. Estimation result showed from 48 fields that are considered depleted from their Np/Ult ratio (hydrocarbon cumulative production over ultimate recovery), Riau and South Sumatera region have large storage capacities which are around 229 and 144 MtCO2 respectively. The ranking of Indonesia sedimentary basins can then be used in making decisions for the large-scale implementation of CCS Project. The potential storage capacity might increase as data more available. The estimates resulted from this study is not a conclusive estimation where degree of geological and economic uncertainty associated with a capacity estimate is still high. However, from this estimation shows that Indonesia has huge potential of CO2 storage in depleted oil and gas reservoirs

National energy policy drawn up by the government through Energy Mix Target 2025 (Presidential Regulation No.5/2006) is still dominated by fossil fuel. Moreover, it is coupled with high dependence on fossil fuel, increasing demand of energy and standard of living and high rate population growth, it can turn Indonesia into one of the biggest emitter in the future. On 2009, the government has pledged a non-binding commitment to reduce country emissions by 26% in 2020. This aspiring target requires great efforts besides reliying on current strategies such as energy mix improvements, the switch to less-carbon intensive fuels and renewable resources deployment as well as conservation. Carbon Capture and Storage (CCS) is one of the climate change mitigation tools with the technological capability to reduce CO2 in substantial amount and deep cut particularly on energy sector. CCS is typically defined as the integrated process of CO2 separation at industrial plants, transportation to storage sites and injection into subsurface formations. This paper explains the possibility of CCS potential deployment in Indonesia by reviewing required components and provides comprehensive understanding in each CCS key lements.
