Enhanced Oil Recovery Techniques for Mature Oil Fields: A Comparative Study

Thesis Abstract

Abstract
This thesis presents a comprehensive investigation into the application of Enhanced Oil Recovery (EOR) techniques in mature oil fields, aiming to compare and analyze their effectiveness in increasing oil production. The study focuses on addressing the challenges faced by the oil industry in maximizing oil recovery from existing mature fields. The research methodology involved a thorough review of existing literature on EOR techniques, followed by a comparative analysis of their performance in mature oil fields. Data collection and analysis were conducted to evaluate the impact of various EOR methods on oil recovery rates and overall field productivity. The introduction provides an overview of the significance of EOR techniques in the oil industry, particularly in mature oil fields where primary and secondary recovery methods have reached their limits. The background of the study highlights the evolution of EOR technologies and their importance in sustaining oil production from mature fields. The problem statement identifies the need for improved recovery methods to optimize oil production in aging fields, while the objectives of the study outline the specific goals and outcomes sought through this research. The literature review chapter critically examines existing studies and research findings on a range of EOR techniques, including chemical, thermal, and gas injection methods. The review identifies key factors influencing the selection and implementation of EOR techniques in mature oil fields, providing a foundation for the comparative analysis conducted in this study. The research methodology chapter details the approach taken in collecting and analyzing data to compare the performance of different EOR methods. The methodology includes data collection from case studies, field trials, and simulation models, as well as statistical analysis to evaluate the effectiveness of each technique in enhancing oil recovery rates. The discussion of findings chapter presents a detailed analysis of the results obtained from the comparative study of EOR techniques in mature oil fields. The findings highlight the strengths and limitations of each method, as well as their impact on oil recovery efficiency and field productivity. The chapter also discusses the implications of the results for the oil industry and provides recommendations for future research and field applications. In conclusion, this thesis summarizes the key findings and insights gained from the comparative study of EOR techniques in mature oil fields. The research contributes to the understanding of the challenges and opportunities in optimizing oil recovery from aging fields and provides valuable recommendations for industry practitioners and researchers. The study underscores the importance of continuous innovation and technological advancements in enhancing oil production sustainability in mature oil fields.
