Northwest Java and East Natuna Field: Perspective To Apply Carbon Capture and Storage (CCS) in Indonesia

摘要

Climate change is becoming most issue discussed in the world since last decade that is believed to occur by the emission of anthropogenic greenhouse-gases in the atmosphere. Carbon dioxide emissions are responsible for the most important greenhouse-gas effects. Therefore developed and developing countries attempt to reduce the CO2 emissions in further decades. Indonesia, as a member of the Kyoto Protocol, plans to reduce CO2 emissions to 26% in 2020. Carbon capture storage (CCS) is one of the technologies to reduce emission and enhanced hydrocarbon recovery. The comprehensive study concerning the technology and application of CCS has been begun in other countries as well as in Indonesia now. Therefore, The Department of Petroleum Engineering of ITB conducts a study concerning the feasibility of CCS application in the petroleum industry. The main purpose of the study is to provide knowledge of CCS system, the effects of impurities on storage operations, and finally the principal storage possibilities in two fields Indonesia, Northwest Java Field and East Natuna. The Northwest Java Field is a back-arc field which consists of many reservoirs-such as Talangakar Formation sandstones, a carbonate reef of Baturaja Formation, carbonate of Upper Cibulakan Formation, and carbonates of Parigi Formation. The most promising formation in Northwest Java field is the Parigi formation.East Natuna Field has similar characteristics with North Java Field, therefore might be suitable also for CO2 injection storage. The research in this paper discussed about feasibility of carbonate formations as CO2 storage. A brief explanation of the geological setting and comparison with other carbonate CO2 storage is also presented. Hopefully, this study will encourage the CCS research and development in Indonesia further.
