Abstract CO2 gas injection is one of the recommended enhanced oil recovery (EOR) methods by injecting C O2 through reservoir pores after the residual saturation is reached, since C O2 dissolves easily in oil phase as confirmed by many other researchers in pertaining field studies. An integrated system is urgently required for assessing C O2-EOR study, covering multi-disciplinary aspects as follows: geology, geophysics, reservoir, production, process and economic. Hence, those systems must be reliable in suggesting final decision for feasibility of CO2-EOR operation program, applicable either for pilot scale or for full scale. This paper is proposing an integrated system evaluation, which has the following features: (1) estimate fraction of dissolved CO2, (2) estimate viscosity reduction, (3) estimate future oil productivity index resulted, (4) forecast incremental oil production, (5) estimate surface facilities equipment design, (6) evaluate economical aspects and (7) generate final decision for feasibility of CO2-EOR operation program. Finally, as the main objective of this program, those systems will present a picture of essential reason why we need to promote or reject CO2-EOR plan program, and also some recommendations will be presented in case the CO2-EOR plan does not perform as expected.

Introduction Indonesia approximately has 998 million BOE (Barrel Oil Equivalent) of national energy demand, relying on crude oil as the main energy source (MEMRRI 2017). Furthermore, 90% of national oil production comes from depleted oil fields. If we persist in this situation without doing any exploration and discoveries, 3.6 billion of proven Indonesia’s oil reserve will completely drained within the next 11 years (SKK Migas 2016).

Pertamina as an Indonesia’s national oil and gas company has about 110 Tscf of natural gas sources, associated with large amount of CO2 content (Suarsana 2010). CO2 could reduce heating value and contribute to global warming this situation can lead to detrimental issues in economic and environmental aspect, but from another perspective we can turn these issues into new opportunity to enhance oil production by employing C O2-EOR
