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

Thesis Abstract

Abstract
Enhanced Oil Recovery (EOR) techniques play a crucial role in maximizing oil production from mature oil fields. This thesis presents a comprehensive comparative analysis of various EOR techniques to determine their effectiveness in enhancing oil recovery from mature oil fields. The research focuses on investigating the key factors that influence the selection and success of EOR methods in mature oil fields, considering aspects such as reservoir characteristics, fluid properties, and economic feasibility. The study begins with an introduction to the challenges associated with mature oil fields and the importance of implementing EOR techniques to optimize oil recovery. A detailed review of the background literature provides insights into the existing EOR methods used in mature oil fields and their respective limitations and advantages. The problem statement highlights the gaps in current research and emphasizes the need for a comparative analysis to identify the most suitable EOR techniques for mature oil fields. The objective of the study is to compare and evaluate the performance of different EOR techniques, including thermal methods (such as steam injection), chemical methods (such as polymer flooding), and gas injection methods (such as CO2 injection), in mature oil fields. The limitations and scope of the study are outlined to provide clarity on the research boundaries and constraints. The significance of the study lies in its potential to contribute to the development of more efficient EOR strategies for maximizing oil recovery from mature oil fields. The methodology chapter presents the research approach, data collection methods, and analytical techniques employed to compare and assess the effectiveness of various EOR techniques. The discussion of findings chapter provides a detailed analysis of the results obtained from the comparative study, including a quantitative evaluation of oil recovery rates, production costs, and environmental impacts associated with different EOR methods. In conclusion, this thesis offers valuable insights into the selection and application of EOR techniques for mature oil fields based on a comparative analysis of their performance. The findings of this study can inform decision-making processes for oil field operators and engineers seeking to optimize oil recovery and extend the productive life of mature oil fields. Overall, the research contributes to advancing knowledge in the field of petroleum engineering and provides practical recommendations for enhancing oil recovery from mature oil fields.
