Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing hydrocarbon production from mature oil fields. This thesis focuses on evaluating and comparing various EOR methods to identify the most effective strategies for enhancing oil recovery in mature oil fields. The study begins with a comprehensive review of the background and significance of EOR techniques in the petroleum industry. The problem statement highlights the challenges faced in extracting remaining oil reserves from mature fields and emphasizes the need for innovative EOR solutions. The objectives of the study include analyzing different EOR methods, assessing their applicability to mature oil fields, and determining their economic feasibility. The literature review in this thesis covers ten key areas related to EOR techniques, including water flooding, chemical flooding, gas injection, thermal methods, and microbial EOR. Each method is examined in terms of its principles, advantages, limitations, and field applications. The research methodology chapter outlines the approach taken to collect and analyze data, incorporating laboratory experiments, field case studies, economic modeling, and simulation studies. Key components of the research methodology include data collection, experimental design, reservoir simulation, economic analysis, and sensitivity analysis. The findings chapter presents a detailed discussion of the results obtained from the analysis of different EOR techniques. This section evaluates the effectiveness of each method in enhancing oil recovery, considering factors such as oil displacement efficiency, production rates, and economic viability. The discussion also addresses the challenges and limitations associated with implementing EOR techniques in mature oil fields, such as reservoir heterogeneity, fluid compatibility, and operational costs. In conclusion, this thesis summarizes the key findings and implications of the study, highlighting the most promising EOR techniques for maximizing oil recovery from mature fields. The research underscores the importance of continuous innovation and technology development in the oil and gas industry to sustain production levels and extend the life of mature oil fields. Overall, the study contributes valuable insights to the field of petroleum engineering by providing a comprehensive analysis of EOR techniques and their applications in mature oil reservoirs.
