Abstract <br /> <br /> <br /> CO2 is the one of the abundant method to enhance oil recovery or people called it EOR, with the purpose to reduce oil viscosity and interfacial tension, so oil will be flowed easily. Advantage of CO2 injection are it can expand oil, miscible with oil because of extraction, vaporization, chromatographic displacement, act as solution gas-drive, could form miscible front, CO2 is also soluble in water, will be miscible with oil, and harmless yet not easy to explode. This study using huff and puff technique or only use one well to act as injection and production well. Huff and puff technique also known as cyclic method, and this study will be simulated single and two cycle, which one is the best case to produce oil that will generate optimum oil production. <br /> <br /> <br /> This technique has been used in Meruap Field with injection composition of CO2 is 99.9% or assumed as pure CO2 injection. This study also will discuss more about CO2 injection design mixing the CO2 itself with another organic compound, and the mixture will be used is the one which allow miscible CO2 injection. The mixture is the one that has MMP (Minimum Miscibility Pressure) lower than 1300. In addition, there is also sensitivity to the percent amount of additive used, the duration of the injection, as well as the duration of the soaking, with the consideration of fixed injection rate of 2 MMSCFD. The longer the injection time means the greater the volume of the injected then will result in greater oil recovery, but this is in contrast to the length of the soaking period.
