Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study

Thesis Abstract

Abstract
Enhanced oil recovery (EOR) techniques play a crucial role in maximizing oil production from mature oil fields. This thesis presents a comparative study of various EOR techniques applied in mature oil fields to assess their effectiveness and feasibility. The research focuses on analyzing the performance of different EOR methods, including chemical, thermal, and gas injection techniques, in enhancing oil recovery rates in mature fields. The study evaluates the potential benefits, limitations, and challenges associated with each EOR technique to provide valuable insights for the oil and gas industry. The introduction chapter provides a comprehensive overview of the research topic, highlighting the importance of EOR in the context of mature oil fields. The background of the study discusses the current state of mature oil fields and the need for advanced recovery methods to optimize oil production. The problem statement identifies the gaps in existing research and the research questions that guide this study. The objectives of the study outline the specific goals and aims of the research, while the limitations and scope of the study define the boundaries and constraints of the research work. The literature review chapter presents a detailed analysis of existing studies and research findings on EOR techniques for mature oil fields. The review covers ten key areas, including the principles of EOR, types of EOR methods, case studies of successful EOR applications, and challenges in implementing EOR in mature fields. This comprehensive review sets the foundation for the research methodology chapter, which outlines the research design, data collection methods, and analytical techniques used in the study. The chapter also discusses the selection criteria for case studies and data analysis procedures. The research methodology chapter further elaborates on the sampling technique, data collection tools, and statistical methods employed to analyze the effectiveness of different EOR techniques in mature oil fields. The discussion of findings chapter presents the results of the comparative study, highlighting the performance metrics, cost-effectiveness, and environmental impact of various EOR methods. The chapter also discusses the implications of the findings for the oil and gas industry and provides recommendations for future research and field applications. In conclusion, this thesis summarizes the key findings and insights gained from the comparative study of EOR techniques for mature oil fields. The research highlights the importance of selecting the most suitable EOR method based on reservoir characteristics, economic viability, and environmental considerations. The study contributes to the existing knowledge on EOR applications and offers valuable recommendations for improving oil recovery rates in mature fields.
