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

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques have become a crucial aspect of the petroleum industry, particularly in mature oil fields where conventional extraction methods have reached their limits. This thesis presents a comprehensive comparative study of various EOR techniques employed in mature oil fields to enhance production rates and maximize recovery. The research aims to evaluate the effectiveness, feasibility, and economic viability of different EOR methods, including chemical, thermal, and miscible gas injection techniques. The introduction provides a background to the study, highlighting the increasing global demand for oil and the challenges faced by the industry in extracting oil from mature fields. The problem statement emphasizes the need for innovative EOR techniques to sustain production levels in aging reservoirs. The objectives of the study are to analyze and compare different EOR methods to determine their applicability in mature oil fields, identify the limitations and challenges associated with each method, and assess the economic and environmental implications of implementing EOR techniques. The literature review explores existing research on EOR techniques, focusing on studies that have investigated the application of various methods in mature oil fields. The review covers key aspects such as the mechanisms of different EOR processes, reservoir characteristics that influence EOR success, and case studies of successful EOR projects in mature fields. The methodology section outlines the research approach, data collection methods, and analytical tools used to compare and evaluate the different EOR techniques. Findings from the comparative study are discussed in detail in chapter four, highlighting the advantages, limitations, and potential risks associated with each EOR method. The analysis considers factors such as reservoir heterogeneity, fluid properties, and operational challenges that influence the selection and implementation of EOR techniques. The conclusion summarizes the key findings of the study and offers recommendations for future research and practical applications in the petroleum industry. Overall, this thesis contributes to the existing body of knowledge on EOR techniques for mature oil fields by providing a comprehensive comparative analysis of different methods. The research findings can inform decision-making processes for oil companies and reservoir engineers seeking to optimize production and maximize oil recovery in aging reservoirs.
