Thesis Abstract

Abstract
This thesis investigates Enhanced Oil Recovery (EOR) techniques for mature oil fields, focusing on a comparative study to identify the most effective methods for maximizing oil production. The declining production rates in mature oil fields necessitate the application of advanced EOR techniques to recover additional reserves. The research aims to evaluate and compare different EOR methods to determine their effectiveness in enhancing oil recovery from mature fields. The study begins with an introduction outlining the background of the research, highlighting the challenges faced by the oil industry in maintaining production levels in mature fields. The problem statement addresses the need for improved recovery techniques to extract remaining oil reserves efficiently. The objectives of the study are to analyze various EOR methods, compare their performance, and identify the most suitable techniques for mature oil fields. The research methodology section describes the approach taken to achieve the study objectives. It includes a detailed explanation of the data collection methods, analysis techniques, and criteria used for comparing EOR techniques. The methodology also considers the limitations and scope of the study, ensuring that the findings are reliable and relevant to the research topic. The literature review examines existing studies on EOR techniques, providing insights into the different methods employed in mature oil fields. The review covers ten key aspects of EOR, including chemical flooding, gas injection, thermal methods, and microbial EOR, among others. By synthesizing and analyzing the literature, this section establishes a foundation for comparing the effectiveness of various EOR methods. The discussion of findings presents the results of the comparative study, highlighting the performance of different EOR techniques in mature oil fields. The analysis considers factors such as oil recovery efficiency, cost-effectiveness, environmental impact, and operational feasibility. By evaluating these aspects, the study aims to identify the most suitable EOR methods for maximizing oil production in mature fields. In conclusion, the thesis summarizes the key findings of the research and offers insights into the implications for the oil industry. The study underscores the significance of implementing advanced EOR techniques to enhance recovery rates and prolong the productive life of mature oil fields. The findings provide valuable guidance for oil operators and decision-makers seeking to optimize production in mature fields through effective EOR strategies. Overall, this research contributes to the understanding of EOR techniques for mature oil fields and offers practical recommendations for improving oil recovery efficiency. By comparing and evaluating different methods, the study advances knowledge in the field of petroleum engineering and provides a basis for further research in optimizing production from mature oil fields.
