Enhanced Oil Recovery Techniques for Sustainable Production in Mature Oil Fields

Thesis Abstract

Abstract
Enhanced oil recovery (EOR) techniques play a crucial role in maximizing hydrocarbon production from mature oil fields, thereby ensuring sustainable energy supply. This thesis explores various EOR methods and technologies that can be employed to enhance oil recovery in mature oil fields. The research focuses on the application of innovative approaches to improve production efficiency, reduce environmental impact, and extend the economic viability of oil reservoirs nearing the end of their productive life. The introduction provides an overview of the importance of EOR in the oil and gas industry, highlighting the challenges faced in mature oil fields and the significance of implementing sustainable production practices. The background of the study delves into the historical development of EOR techniques, emphasizing the evolution of methods such as thermal, chemical, and gas injection processes. The problem statement identifies the key issues associated with declining production rates in mature oil fields and the need for advanced EOR solutions to optimize recovery. The objectives of the study aim to evaluate the effectiveness of different EOR techniques, assess their environmental impact, and propose recommendations for sustainable production practices. The literature review presents a comprehensive analysis of existing research on EOR technologies, covering topics such as reservoir characterization, fluid properties, rock-fluid interactions, and field implementation strategies. The review highlights recent advancements in EOR methods and identifies gaps in current knowledge that warrant further investigation. The research methodology outlines the approach taken to collect and analyze data, including field studies, laboratory experiments, simulation modeling, and economic assessments. The methodology also describes the criteria for selecting case studies and evaluating the performance of EOR techniques in mature oil fields. The discussion of findings presents the results of the research, including the comparative analysis of different EOR methods, their technical feasibility, economic viability, and environmental considerations. The findings provide insights into the challenges and opportunities of implementing EOR technologies in mature oil fields to achieve sustainable production targets. Finally, the conclusion summarizes the key findings of the study and offers recommendations for future research and industry practices. The thesis contributes to the advancement of EOR knowledge and provides valuable insights for oil and gas professionals, researchers, and policymakers seeking to enhance oil recovery and promote sustainability in mature oil fields. In conclusion, this thesis underscores the importance of employing advanced EOR techniques for sustainable production in mature oil fields, emphasizing the need for innovation, collaboration, and strategic planning to address the challenges of declining reservoir performance and ensure long-term energy security. Overall, this research contributes to the ongoing efforts to optimize oil recovery, extend the productive life of mature oil fields, and support the transition towards a more sustainable energy future.
