Thesis Abstract

Abstract
The efficient recovery of oil from mature oil fields is crucial for maximizing production and extending the economic viability of oil reservoirs. This study focuses on evaluating and comparing various enhanced oil recovery (EOR) techniques to determine their effectiveness in mature oil fields. The research aims to address the challenges associated with declining oil production rates in these fields and explore innovative strategies to enhance oil recovery. The introduction provides a comprehensive overview of the background of the study, highlighting the significance of EOR techniques in addressing the challenges faced by mature oil fields. The problem statement identifies the key issues related to declining oil recovery rates and the limitations of existing recovery methods. The research objectives outline the specific goals of the study, including evaluating different EOR techniques, comparing their performance, and identifying the most effective strategies for mature oil fields. The literature review chapter presents an in-depth analysis of existing studies and research findings related to EOR techniques. Ten key items are discussed, covering topics such as water flooding, gas injection, chemical flooding, thermal methods, and emerging technologies in the field of enhanced oil recovery. The chapter synthesizes relevant literature to provide a comprehensive understanding of the current state of EOR technologies and their applications in mature oil fields. The research methodology chapter outlines the approach taken to investigate and compare EOR techniques for mature oil fields. The methodology includes data collection methods, analysis techniques, and experimental procedures for evaluating the performance of different EOR methods. The chapter also discusses the selection criteria for oil fields, simulation models used, and the parameters considered in the comparative analysis. In the discussion of findings chapter, the results of the comparative study on EOR techniques are presented and analyzed. The chapter highlights the performance of each technique in terms of oil recovery efficiency, cost-effectiveness, environmental impact, and operational challenges. The findings provide valuable insights into the most suitable EOR methods for enhancing oil recovery in mature oil fields. The conclusion and summary chapter offer a comprehensive overview of the key findings, implications, and recommendations of the study. The conclusions drawn from the research findings are summarized, and practical recommendations are provided for the implementation of effective EOR strategies in mature oil fields. The chapter also discusses the significance of the study in advancing the field of enhanced oil recovery and addressing the challenges of declining oil production in mature reservoirs. In conclusion, this thesis contributes to the understanding of enhanced oil recovery techniques for mature oil fields through a comparative study of different EOR methods. The research findings provide valuable insights for oil industry professionals, researchers, and policymakers seeking to enhance oil recovery rates and extend the productive life of mature oil fields.
