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 comprehensive comparative study of various EOR techniques applied to mature oil fields, aiming to enhance recovery rates and extend the economic life of these fields. The research investigates the effectiveness of different EOR methods, including chemical, thermal, and gas injection techniques, in improving oil recovery from mature reservoirs. The study evaluates the technical feasibility, economic viability, and environmental impact of each EOR method to provide insights into their applicability in real-world oil recovery operations. The introductory chapter sets the foundation for the study by outlining the background of EOR techniques in the petroleum industry and identifying the problem statement related to declining oil production in mature fields. The research objectives focus on assessing the performance of various EOR methods, identifying their limitations, and determining the scope and significance of the study. The chapter concludes with a detailed structure of the thesis and definitions of key terms used throughout the research. The literature review chapter provides a comprehensive analysis of existing studies and industry practices related to EOR techniques for mature oil fields. Ten key areas are explored, including the principles of EOR, types of EOR methods, field applications, challenges, and future trends in EOR technology. The chapter synthesizes relevant literature to provide a solid theoretical foundation for the research. The research methodology chapter outlines the approach and methods employed in conducting the comparative study. Eight key elements are discussed, including data collection methods, analytical tools, simulation techniques, and criteria for evaluating EOR performance. The chapter details the process of data analysis and interpretation to draw meaningful conclusions from the research findings. Chapter four presents an in-depth discussion of the research findings, comparing the performance of different EOR techniques in terms of oil recovery efficiency, cost-effectiveness, and environmental impact. The results of the study highlight the strengths and weaknesses of each EOR method and provide insights into their optimal application in mature oil fields. The chapter also discusses practical implications and recommendations for industry stakeholders seeking to enhance oil recovery from mature reservoirs. The conclusion and summary chapter synthesize the key findings of the research and highlight the implications for the petroleum industry. The study underscores the importance of adopting tailored EOR strategies for mature oil fields to maximize oil production and economic returns. Recommendations for future research directions and potential innovations in EOR technology are also discussed to guide further advancements in the field. In conclusion, this thesis contributes to the understanding of EOR techniques for mature oil fields through a comprehensive comparative study. The research findings offer valuable insights for oil and gas professionals, researchers, and policymakers seeking to optimize oil recovery from mature reservoirs and sustainably meet global energy demands.
