Thesis Abstract

Abstract
The aim of this study is to investigate and compare various enhanced oil recovery (EOR) techniques for mature oil fields, with the objective of enhancing the extraction efficiency and prolonging the productive lifespan of such fields. The significance of this research lies in addressing the challenges faced by the petroleum industry in maximizing oil recovery from mature fields, which are characterized by declining production rates and a significant amount of remaining oil reserves. By analyzing and comparing different EOR methods, this study seeks to provide valuable insights into the most effective techniques for enhancing oil recovery in mature fields. The introduction provides an overview of the research focus, highlighting the importance of EOR techniques in the context of mature oil fields. The background of the study delves into the current state of mature oil fields globally and the challenges associated with conventional oil recovery methods. The problem statement identifies the gap in knowledge regarding the optimal EOR techniques for mature fields and underscores the need for further research in this area. The objectives of the study are outlined to guide the research process, which includes comparing the efficiency and feasibility of various EOR methods such as chemical flooding, thermal methods, and gas injection. The limitations of the study are acknowledged to provide a transparent view of the research scope and potential constraints. The scope of the study defines the boundaries within which the research will be conducted, focusing on mature oil fields and specific EOR techniques. The significance of the study lies in its potential to contribute to the optimization of oil recovery processes in mature fields, thereby increasing the overall productivity and economic viability of these assets. The structure of the thesis provides an overview of the organization of the research, outlining the chapters and their respective contents.
