Integrated Reservoir Management for Enhanced Oil Recovery in Mature Fields

Thesis Abstract

Abstract
The oil and gas industry plays a critical role in meeting global energy demands, with mature fields being a significant source of hydrocarbon production. However, as these fields age, their reservoirs exhibit declining production rates, necessitating the implementation of enhanced oil recovery (EOR) techniques to maximize hydrocarbon extraction. This thesis focuses on the application of integrated reservoir management strategies to improve oil recovery in mature fields. The study aims to investigate the challenges associated with mature field development, analyze the effectiveness of various EOR methods, and propose an integrated approach for reservoir management to optimize production. The research methodology involves a comprehensive literature review to examine existing practices and technologies in reservoir management and EOR. The study utilizes a mix of qualitative and quantitative analyses to evaluate the performance of different EOR techniques, considering factors such as reservoir characteristics, fluid properties, and economic feasibility. Field case studies and simulation models are used to demonstrate the application of integrated reservoir management in enhancing oil recovery from mature fields. Chapter 1 provides an introduction to the study, presenting the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter 2 presents a detailed literature review on EOR methods, reservoir management practices, and challenges in mature field development. The chapter examines ten key aspects related to EOR and reservoir management, highlighting current trends and advancements in the industry. Chapter 3 outlines the research methodology, detailing the approach taken to analyze reservoir data, evaluate EOR techniques, and develop an integrated reservoir management strategy. The chapter includes discussions on data collection, analysis tools, simulation techniques, and validation methods used in the study. Eight key components of the research methodology are presented to provide a comprehensive understanding of the investigative process. Chapter 4 delves into the discussion of findings, presenting the results of the case studies and simulation models conducted to assess the effectiveness of integrated reservoir management in enhancing oil recovery from mature fields. The chapter evaluates the performance of different EOR methods and their impact on reservoir production, providing insights into the benefits and challenges of implementing integrated strategies. Chapter 5 serves as the conclusion and summary of the thesis, summarizing the key findings, discussing the implications of the research, and offering recommendations for future studies. The chapter highlights the significance of integrated reservoir management in optimizing oil recovery from mature fields and emphasizes the importance of sustainable practices in the oil and gas industry. In conclusion, this thesis underscores the importance of integrated reservoir management for enhancing oil recovery in mature fields. By combining reservoir engineering principles, EOR techniques, and advanced technologies, operators can maximize hydrocarbon extraction, prolong field life, and improve overall reservoir performance. The study contributes to the existing body of knowledge in reservoir management and EOR, offering insights that can benefit the oil and gas industry in addressing the challenges of mature field development and sustaining global energy supply.
