Enhanced Oil Recovery Techniques for Mature Oil Fields

Thesis Abstract

Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing oil production from mature oil fields. As oil reservoirs age, conventional production methods become less effective in extracting the remaining oil reserves. This thesis focuses on investigating and evaluating various EOR techniques that can be applied to mature oil fields to enhance oil recovery rates and extend the economic life of these reservoirs. The research begins with a comprehensive review of the background of the study, highlighting the challenges associated with mature oil fields and the increasing importance of implementing EOR techniques. The problem statement identifies the declining oil production rates in mature oil fields and the need for innovative solutions to optimize oil recovery. The objectives of the study are outlined to provide a clear direction for the research, focusing on evaluating the effectiveness of different EOR methods in mature oil fields. The study addresses the limitations and constraints that may impact the research outcomes, including technical, financial, and operational challenges. The scope of the study defines the boundaries within which the research will be conducted, outlining the specific types of EOR techniques and mature oil fields that will be examined. The significance of the study emphasizes the potential impact of implementing EOR techniques in mature oil fields, both in terms of economic benefits and environmental sustainability. The structure of the thesis is presented to guide the reader through the organization of the research, including the chapters and sub-sections that will be covered. Definitions of key terms are provided to ensure clarity and understanding of the terminology used throughout the thesis. Chapter two consists of a detailed literature review that explores existing research and case studies on EOR techniques in mature oil fields. The review covers a wide range of topics, including chemical, thermal, and gas injection methods, as well as recent advancements in EOR technology. Chapter three outlines the research methodology, detailing the research design, data collection methods, and analysis techniques that will be employed. The chapter also includes information on the selection criteria for case studies and the process for evaluating the results. Chapter four presents a comprehensive discussion of the research findings, highlighting the effectiveness of different EOR techniques in enhancing oil recovery rates in mature oil fields. The chapter includes a detailed analysis of the case studies and provides insights into the practical applications of EOR methods. Finally, chapter five offers a conclusion and summary of the thesis, summarizing the key findings, discussing the implications of the research, and offering recommendations for future studies and industry applications. Overall, this thesis aims to contribute to the knowledge and understanding of EOR techniques for mature oil fields and provide valuable insights for industry professionals and researchers in the field of petroleum engineering.
