Enhanced Oil Recovery Techniques for Mature Oilfields: A Comparative Study

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing oil production from mature oilfields. This thesis presents a comprehensive comparative study of various EOR techniques employed in mature oilfields to enhance oil recovery efficiency and extend the economic life of these reservoirs. The study focuses on analyzing the effectiveness, applicability, and limitations of different EOR methods, including thermal methods, chemical injection, and gas injection techniques. The introduction provides an overview of the importance of EOR in the oil and gas industry, particularly for mature oilfields facing declining production rates. The background of the study establishes the context for the research by highlighting the challenges associated with extracting oil from mature reservoirs and the need for advanced recovery methods. The problem statement identifies the gaps in existing literature regarding the comparative analysis of EOR techniques for mature oilfields and sets the research objectives to address these gaps. The literature review critically examines previous studies and industry practices related to EOR techniques, identifying key factors influencing the selection and implementation of these methods in mature oilfields. The research methodology outlines the approach taken to collect and analyze data, including case studies, simulations, and field experiments. The findings chapter presents a detailed discussion of the results obtained from the comparative analysis, highlighting the advantages, limitations, and success factors of each EOR technique. Through this comparative study, the thesis aims to provide valuable insights for oil and gas operators, engineers, and researchers involved in the development and optimization of EOR projects for mature oilfields. The conclusion summarizes the key findings of the research and offers recommendations for future studies and practical applications in the field of EOR. Overall, this thesis contributes to the advancement of knowledge in EOR technology and its application in maximizing oil recovery from mature oilfields, ultimately helping to sustainably meet global energy demands.
