Abstract
Microbial Enhanced Oil Recovery (MEOR) involves injecting nutrients into oil reservoirs to enhance the oil recovery. This technology has the capacity to increase the amount of oil that can be extracted. Microbes in the reservoir oil can be activated by nutrients that they come into contact with, leading to a response. The interaction between nutrients and microbes in the reservoir oil can optimize oil recovery efficiency by catalyzing the decomposition of hydrocarbon chains. This research is written based on the information provided. The objective of this study is to evaluate the efficacy of nutrition injection by analyzing data obtained from scientific journals. The aim of this study is to investigate the impact of different injection-production well designs and the most effective nutrient injection rate on enhancing oil recovery and the recovery factor value in the DHP Field using MEOR injection. The methodology employed in this study comprises a comprehensive review of existing literature and the utilization of reservoir simulation techniques. This data is subsequently utilized to conduct reservoir simulation for nutrient injection using a simulator. The problem lies in the fact that the scenarios generated only incorporate sensitivity analysis of the injection-production well layouts and injection rates, without taking into account the economic factors. The study^s findings indicate that employing suitable nutrient injection well layouts and optimizing the nutrient injection rate can enhance oil recovery in the MEOR process through nutrient injection. The simulation findings for the base case, Scenario 1, 2, 3, and 4 yielded oil recovery factors of 12.17%, 13.20%, 17.13%, 14.23%, and 16.36% respectively. Hence, the most optimal approach for enhancing oil recovery in the DHP Field by MEOR nutrition injection is Scenario 2, which involves a five-spot injection design and an injection rate of 700 bbl/day.
