Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Mature Oil Fields" focuses on the utilization of advanced techniques to enhance oil recovery from mature oil fields. As oil fields mature, the natural pressure within the reservoir decreases, leading to lower oil production rates. This necessitates the implementation of enhanced oil recovery (EOR) techniques to maximize oil extraction and prolong the productive life of the reservoir. The research will begin with a comprehensive introduction that outlines the background of the study, the problem statement, research objectives, limitations, scope, significance of the study, structure of the thesis, and definition of key terms. This chapter will set the stage for the subsequent sections by providing a clear understanding of the research context and objectives. Chapter two will involve an in-depth literature review that examines existing studies, theories, and practices related to enhanced oil recovery techniques for mature oil fields. This chapter will explore various EOR methods, such as water flooding, gas injection, chemical flooding, thermal methods, and microbial EOR, to identify their effectiveness in enhancing oil recovery from mature reservoirs. Chapter three will focus on the research methodology, detailing the research design, data collection methods, data analysis techniques, and the criteria for selecting case studies or field trials.
