Abstract
Indonesia oil production is in the stage of mature fields dominant having a current oil recovery factor of 32% leaving underground about 48.6 billion barrels of unrecoverable oil in place ( SKK Migas, 2016 ). At this stage, Enhanced Oil Recovery (EOR) is a mandatory choice to lift up the unrecoverable oil.
SKK Migas and Bandung Institute of Technology (ITB) conducted a study in 2015 to evaluate the EOR potential of 136 fields in Indonesia. EOR screening processes was firstly conducted using the combination of Al-Adasani (2011) and Taber (1983 & 1997 ) studies to determine the most suited EOR methods for each reservoir. Following the screening results is forecasting additional reserves for each reservoir applying the US Department of Energy (DOE) formula. Based on the additional reserves, we are seeking the best field candidates for CO2 EOR.
The CO2 EOR technology is a proven and mature technology. Through mapping the CO2 sources and the injected fields in Indonesia, several fields have been selected for pilot projects. The success of this CO2 EOR in Indonesia would mean the second life of national oil production. This paper shows one field project that is considered to be prospective.
