One of the applications of biotechnology is the use of strains in the petroleum industry, which has been considered due to the vastness of the petroleum industry. The basis of microbial growth is based on the biological production of the strains and the IR effects on the properties of the oil, water, or the rock itself. This operation is performed by specific strains that can grow in reservoir conditions and also have the ability to increase oil production through their metabolism. By far the most common strains involved in the oil harvesting process were bacteria. These bacteria, with a variety of products, cause the process of harvesting. Therefore, this study aimed to optimize the factors affecting the performance of the microbial harvesting process. Experiments used in this study included the evaluation of oil recovery in fluid injection mode. Macroscopic observations contain double selective strain biopolymers 59TMU and 57TMU in the oil microbial harvesting process. Optimal values of each effective parameter are obtained through an experimental analysis using Design-Expert software and a complete factorial method. According to the results, biopolymer concentration, sodium chloride salt concentration, and strain type are considered as the most important parameters in the present study. The final oil recovery improvement with 59TMU and 57TMU strains was 47% and 53%, respectively. [ABSTRACT FROM AUTHOR] |
