Integrated Reservoir Characterization and Simulation for Enhanced Oil Recovery in Mature Oilfields

Thesis Abstract

Abstract
The oil and gas industry continues to face challenges in maximizing recovery from mature oilfields. Enhanced oil recovery (EOR) techniques have become increasingly important to improve production rates and extend the life of these fields. This thesis focuses on the application of integrated reservoir characterization and simulation to optimize EOR strategies in mature oilfields. The research aims to enhance understanding of the reservoir properties and fluid behavior through advanced characterization techniques, and to develop accurate reservoir models for simulating EOR processes. Chapter One provides an introduction to the research topic, highlighting the background of study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. The literature review in Chapter Two delves into ten key areas related to reservoir characterization, simulation techniques, EOR methods, and case studies of successful applications in mature oilfields. Chapter Three outlines the research methodology, including detailed descriptions of data collection methods, reservoir characterization techniques, simulation software used, model calibration procedures, sensitivity analysis, and uncertainty assessment. The chapter also discusses the integration of various data sources and modeling approaches to create a comprehensive reservoir model for EOR optimization. In Chapter Four, the findings of the study are presented and discussed in detail. The results of reservoir characterization and simulation studies are analyzed to identify key parameters influencing EOR performance in mature oilfields. The chapter also includes a comparison of different EOR methods and their feasibility for specific reservoir conditions, as well as recommendations for optimizing EOR strategies based on the simulation outcomes. Finally, Chapter Five concludes the thesis by summarizing the key findings, discussing the implications of the research, and highlighting potential areas for future work. The research contributes to the field of petroleum engineering by providing a systematic approach to integrating reservoir characterization and simulation for enhanced oil recovery in mature oilfields. The insights gained from this study have the potential to guide decision-making processes for maximizing oil production and extending the economic life of mature oilfields.
