Project Overview

The project titled "Assessment of Enhanced Oil Recovery Techniques in Mature Oilfields" aims to investigate and evaluate the effectiveness of different enhanced oil recovery (EOR) techniques in mature oilfields. Mature oilfields are characterized by declining production rates and the need for advanced methods to recover additional hydrocarbons. The study will focus on assessing various EOR methods such as thermal, chemical, and gas injection techniques to enhance oil recovery efficiency in these mature fields. The background of the study highlights the importance of maximizing oil recovery from mature fields to meet energy demands and extend the economic lifespan of oil reservoirs. As conventional oil production declines, EOR techniques offer a promising solution to unlock remaining reserves and increase overall oil production. The problem statement addresses the challenges faced in implementing EOR techniques in mature oilfields, including technical complexities, high costs, and environmental considerations. By evaluating the performance of different EOR methods, the research aims to identify the most suitable techniques for application in mature fields. The objectives of the study include assessing the potential of EOR techniques to improve oil recovery rates, analyzing the economic viability of implementing these methods, and evaluating the environmental impact of EOR operations in mature oilfields. By achieving these objectives, the research seeks to provide valuable insights for oil companies and policymakers to make informed decisions regarding EOR projects. The limitations of the study acknowledge potential constraints such as data availability, time constraints, and budget limitations that may impact the scope and depth of the research findings. Despite these limitations, the study aims to provide a comprehensive analysis of EOR techniques in mature oilfields. The scope of the study encompasses a review of literature on EOR methods, case studies of successful EOR projects in mature fields, economic analysis of EOR implementation, and environmental considerations associated with EOR operations. The research will focus on both theoretical frameworks and practical applications of EOR techniques in real-world scenarios. The significance of the study lies in its potential to contribute valuable insights to the field of petroleum engineering by identifying best practices for EOR implementation in mature oilfields. The findings of the research are expected to help industry professionals optimize oil recovery strategies, improve production efficiency, and extend the lifespan of mature oil reservoirs. The structure of the research includes a detailed overview of the research methodology, which involves data collection, analysis techniques, modeling approaches, and simulation studies to evaluate the performance of EOR techniques. The research will be organized into distinct chapters, each focusing on specific aspects of EOR assessment in mature oilfields. In conclusion, the project on the "Assessment of Enhanced Oil Recovery Techniques in Mature Oilfields" aims to advance the understanding of EOR methods and their applicability in mature oilfield settings. By investigating the effectiveness, economics, and environmental impact of EOR techniques, the research seeks to provide valuable insights for the oil and gas industry to optimize oil recovery strategies and maximize production efficiency in mature fields.
