This production system produces oil from wells after drilling and well compressions. Over time, the production of a well may decrease due to several parameters of pressure drop and the presence of clay which makes the pipe diameter narrower. There are several methods used to increase the decrease in production including adding artificial lifts such as sucker rod pump, electric submersible pump and gas lift, reservoir stimulation and pipe cleaning if the pipe diameter is reduced due to clay. The well has been installed an artificial lift is a gas lift and this well need an optimization to increase its production. The EC-6 well optimization is planned by comparing the lift-up scenario of the gas lift by adjusting the rate of gas injection and deepening the orifice injection and also an installation of electrical submersible pump.

Therefore, the purpose of this study is to analyze the effect of CO2 injection on the value of recovery factor with one-dimensional simulation using CMG. To be able to make an accurate simulation model, it is necessary to do validation by comparing the results obtained with the CO2 injection test from experiments in the laboratory. Laboratory experimental data used in this study is from Vulin’s literature. The result of recovery factor for X-field is 98.80%. From the results of this study, it is known that the injection rate of CO2 has no effect on changes in recovery factor. However, the difference of CO2 injection pressure in these two samples influences the change in recovery factor. The higher injection pressure of CO2 in an immiscible condition is, the higher the value of the recovery factor is achieved. In addition, the difference in oil composition in these two samples affects the value of MMP, where the higher the intermediate component of a reservoir fluid is, the lower the MMP will be. X-field has a high intermediate component fraction, therefore the value of MMP obtained is lower than the MMP from Vulin’s literature.

The natural gas reserve is planned to be extracted by utilizing 18 subsea production wells connected to five subsea manifolds at a depth of 300 ‒ 1000 m at below sea level. Gas production will be done by using FPSO. Produced gas then will be pumped to onshore processing facilities on Yamdena island through undersea pipeline that used corrosion resistant alloy as long as up to 100 km in length. The natural gas processing would either be done by building an LNG facility scenario or building a GTL facility scenario on Yamdena island. The LNG scenario would produce the natural gas into LNG and gas condensate. While the GTL scenario would produce the natural gas as a synthetic liquid fuel such as LPG, naphtha, kerosene, and diesel.
