Abstract
A coreflooding experiment was conducted in the enhanced oil recovery (EOR) laboratory, where the biosurfactant ^U-Champ^ was injected into the synthetic core. The experiment demonstrated that it yielded a higher oil recovery compared to waterflooding. Regrettably, the experiment employed a sole concentration of biosurfactant. In order to determine the most favorable conditions for the ^U-Champ^ biosurfactant, a simulation experiment was conducted using commercially available software. Three scenarios have been developed to forecast the effectiveness of u-champ biosurfactant injection. The initial simulation emphasizes concentration, whereas the subsequent scenarios prioritize soaking time. The study found that the optimal outcome yielded an oil recovery rate of 87.46% by utilizing a 6% concentration of u-champ biosurfactant and soaking the solution for 1 hour, 8 hours, and 10 hours. This experiment yielded superior results compared to a laboratory experiment including a 7.5% concentration of u-champ biosurfactant. The experiment involved soaking the mixture for 1 hour, 24 hours, and 48 hours, resulting in an oil recovery rate of 81.58%.
