Abstract

Oil and gas are energy sources that experience the fastest growth among other energy sources.The oil recovery process can be divided into three recovery stages, namely primary oil recovery, secondary recovery and tertiary recovery or commonly called Enhanced oil recovery (EOR).Enhanced oil recovery (EOR) is an oil recovery used to recover residual oil that cannot be recovered by using waterflooding.According to the US Department of Energy, the tertiary recovery method has a successful recovery factor of up to 75%.EOR also helps reduce CO 2 emissions.However, to get optimal results for CO 2 EOR, several parameters must be optimized, such as mass flow rate, injection pressure and temperature.To create a pressure drop model for CO 2 EOR, several equations are used, including the Begg's-brill equation for the injection well dan production well model, the Darcy equation for the reservoir model.Based on the optimization results using Genetic algorithm and Particle swarm optimization, it was found that the profit increased by 97.4782% and 97.478%, respectively, with an increase from 994.2268 USD/days to 39425.92USD/day for Genetic algorithm and 994.2268USD/days to 39422.95USD/day for Particle Swarm Optimization (PSO).
