Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing hydrocarbon production from mature oilfields. This thesis focuses on the optimization of EOR techniques in mature oilfields to enhance oil recovery efficiency and extend the economic life of oil reservoirs. The study begins with an introduction to the importance of EOR in the oil and gas industry and highlights the challenges faced in mature oilfields. A comprehensive review of existing literature on EOR techniques, reservoir characteristics, and field applications is presented to provide a theoretical framework for the research. The research methodology section outlines the approach taken to optimize EOR techniques in mature oilfields. This includes data collection, analysis, simulation studies, and field experiments to evaluate the performance of different EOR methods. The study investigates various EOR techniques such as water flooding, gas injection, chemical flooding, thermal methods, and hybrid processes to determine the most effective approach for specific reservoir conditions. The findings from the research reveal the impact of reservoir heterogeneity, fluid properties, well spacing, and operating parameters on the efficiency of EOR techniques. Simulation studies demonstrate the potential for increased oil recovery through the optimization of injection strategies, fluid properties, and well configurations. Field experiments validate the simulation results and provide practical insights into the implementation of optimized EOR techniques in mature oilfields. The discussion section delves into the implications of the findings for the oil and gas industry, highlighting the economic benefits of optimized EOR techniques. The study emphasizes the importance of reservoir characterization, monitoring, and control strategies in maximizing oil recovery and minimizing operational costs. Recommendations are provided for future research directions and practical guidelines for the application of optimized EOR techniques in mature oilfields. In conclusion, the optimization of EOR techniques in mature oilfields presents a significant opportunity to enhance oil recovery efficiency, increase hydrocarbon reserves, and extend the economic life of oil reservoirs. By integrating advanced reservoir engineering principles with field applications, this research contributes to the development of sustainable EOR practices in the oil and gas industry. The findings offer valuable insights for oilfield operators, reservoir engineers, and researchers seeking to maximize the potential of mature oilfields through optimized EOR techniques.
