Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing hydrocarbon production from mature oil fields. As oil reserves become increasingly depleted, the need for innovative and efficient EOR methods becomes more pressing. This thesis focuses on exploring various EOR techniques that can be applied to mature oil fields to enhance oil recovery rates and prolong the economic life of these reservoirs. The introduction provides an overview of the importance of EOR in the oil and gas industry, particularly in the context of mature oil fields. The background of the study discusses the challenges faced in extracting oil from mature reservoirs, such as declining production rates and increasing water cut. The problem statement highlights the need for effective EOR techniques to mitigate these challenges and improve oil recovery efficiency. The objectives of the study are to evaluate different EOR methods, assess their applicability to mature oil fields, and analyze their effectiveness in enhancing oil recovery rates. The limitations of the study are outlined, including constraints on data availability and the complexity of reservoir conditions. The scope of the study defines the boundaries within which the research will be conducted, focusing on specific EOR techniques and their potential impact on mature oil fields. The significance of the study lies in its contribution to the field of petroleum engineering by providing insights into practical EOR applications for mature oil fields. The structure of the thesis outlines the organization of the research, including chapters on literature review, research methodology, discussion of findings, and conclusion. The literature review encompasses a comprehensive analysis of existing research on EOR techniques, with a focus on their implementation in mature oil fields. Key topics include thermal methods, chemical methods, and gas injection techniques, among others. The review identifies gaps in current knowledge and highlights areas for further investigation. The research methodology section outlines the approach taken to evaluate EOR techniques for mature oil fields, including data collection, analysis, and modeling. Specific methods such as reservoir simulation and laboratory experiments are employed to assess the feasibility and effectiveness of different EOR methods. In the discussion of findings chapter, the results of the research are presented and analyzed, with a focus on the performance of various EOR techniques in mature oil fields. Factors such as reservoir characteristics, fluid properties, and economic considerations are considered in evaluating the applicability of different methods. The conclusion and summary chapter provide a synthesis of the key findings and insights from the study, including recommendations for future research and practical implications for the oil and gas industry. Overall, this thesis contributes to the body of knowledge on EOR techniques for mature oil fields and offers valuable guidance for optimizing oil recovery in these challenging environments.
