Source Sink Matching for Field Scale CCUS CO2-EOR Application in Indonesia

Abstract

The carbon capture utilization and storage (CCUS) referred in this paper is limited to the use of CO₂ to the enhanced oil recovery (CO₂-EOR). The CCUS CO₂-EOR technology can magnify oil production substantially while a consistent amount of the CO₂ injected remains sequestrated in the reservoir, which is beneficial for reducing the greenhouse gas emission. Therefore, this technology is a potentially attractive win-win solution for Indonesia to meet the goal of improved energy supply and security, while also reducing CO₂ emissions over the long term. The success of CCUS depends on the proper sources-sinks matching. This paper presents a systematic approach to pairing the CO₂ captured from industrial activities with suitable oil fields for CO₂-EOR. Inventories of CO₂ sources and oil reservoirs were done through survey and data questionnaires. The process of sources-sinks matching was preceded by identifying the CO₂ sources within the radius of 100 and 200 km from each oil field and clustering the fields within the same radius from each CO₂ source. Each cluster is mapped on the GIS platform included existing and planning right of way for trunk pipelines. Pairing of source-sink are ranked to identify high priority development. Results of this study should be interest to project developers, policymakers, government agencies, academicians, civil society and environmental non-governmental organization in order to enable them to assess the role of CCUS CO₂-EOR as a major carbon management strategy.
