CO2 sink and source matching for better CO2 utilization in increasing oil production: Case study of field X and Y in Indonesia

New discoveries of oil and gas fields in Indonesia have now shifted into CO2 rich fields. 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 value into the disposed CO2. This publication offers an alternative of disposing CO2 from CO2 rich gas fields by injecting it into oil reservoir through CO2−EOR. Despite its urgency, CO2-EOR has not been implemented on a full field scale in Indonesia due to higher price of captured CO2. Therefore, this publication proposes a cluster-based approach to reduce CO2 transportation and compression costs. Based on two gas producing fields, X and Y Field, a classification is then provided by this study to address the suitability of CO2−EOR implementation in the nearby fields. This publication is hoped to become a reference on how to develop cost-efficient CO2−EOR.
