Abstract
New discoveries of oil and gas fields in Indonesia have now shifted into CO2 rich fields, where the CO2 will become a major
obstacle in developing the fields economically. One of the issues in developing CO2 rich fields is how to dispose the CO2
safely or even adding some added value into the disposed CO2. This presentation offers an alternative of disposing CO2 fromCO2 rich gas fields by injecting it into oil and gas reservoirs by means of CO2-EOR and CO2-EGR. Despite its urgency,
CO2-EOR and CO2-EGR has not been implemented on a full field scale in Indonesia due to higher price of captured CO2.
One of the biggest challenges in reducing CO2 emission in Indonesia’s oil and gas industries is the constantly growing needof fossil fuel as well as the lack of carbon tax on Indonesia’s law. Carbon tax, in which a tax is imposed carbon generating
activities, has been successfully applied in several countries, but not in Indonesia. Fortunately, recently the government ofIndonesia declared that CCUS will be supported, since it could give additional economic benefit an on the same time thereduction of greenhouse gas from energy sector could be conducted. Besides that, the government of Indonesia hasdeveloped the draft of Presidential Decree related to economic value of carbon to speed up the NDC target and to control theGHG emission for national development.
This presentation will explain the current status of Gundih CCUS Project, which will be part of JCM implementation.
Gundih CCUS project becomes more interesting, because after injection 10 million tons of CO2 within 10 years, there will
be incremental gas production of about 36 BSCF. The economic benefit from this incremental production is about 3 timehigher than the total CAPEX. If JCM scheme could be implemented, the economic benefit from this project is even higher.
Currently, the National CoE of CCS, CCUS and Flared Gas Utilization at Institut Teknologi Bandung, Pertamina andconsortium from Japan (Janus Co. Ltd., J-Power, JOE and Fukada Geological Institute) are working together for conducting
the FS JCM. CoE at ITB is also working together with JANUS Co. Ltd. for developing CO2
Later, we propose to develop cluster-based approach to reduce CO2 transportation and compression cost, besides obtaining
additional recovery from the oil fields that are implemented the CO2-EOR. This approach was studied in several areas inIndonesia. This study presents an effort to classify source and sink of CO2-EOR/EGR. Some fields are major gas producers’
field with high CO2 content, therefore efforts should be taken to utilize the CO2, not only as a flare gas that has the potential
to pollute its surrounding areas. It is then decided that the CO2 will be utilized and sold as EOR media to nearby fields,
however, care should be taken in order to ensure the economic and technical aspect of CO2 injection itself. Prior to field
selection and calculation, a screening is performed based on available criteria in order to find the most suitable target fields
based on reservoir properties and the remaining oil in place.
As conclusion, it is hoped that this study could be used as a reference on how to develop cost efficient CO2-EOR and CO2EGR, especially in Indonesia.
