Thesis Overview

The project titled "Optimization of Enhanced Oil Recovery Techniques for Mature Oil Fields" aims to address the challenges faced in extracting oil from mature oil fields by exploring and optimizing enhanced oil recovery (EOR) techniques. Mature oil fields are characterized by declining production rates and the presence of trapped oil that is difficult to extract using conventional methods. Therefore, the need to enhance oil recovery from these fields is crucial to maximize production and extend the economic life of the reservoirs. The research will focus on analyzing and optimizing various EOR techniques such as thermal methods (steam injection, in-situ combustion), chemical methods (polymer flooding, surfactant flooding), and gas injection methods (CO2 injection, gas cycling). By studying the effectiveness of these techniques in mature oil fields, the research aims to identify the most suitable EOR method or combination of methods for optimal oil recovery. The project will involve a comprehensive literature review to understand the current state-of-the-art in EOR techniques, including their advantages, limitations, and field applications. This review will provide a solid foundation for evaluating and comparing different EOR methods in the context of mature oil fields. Furthermore, the research methodology will include simulation studies using reservoir modeling software to assess the performance of various EOR techniques under different reservoir conditions. Sensitivity analysis will be conducted to evaluate the impact of key parameters such as oil viscosity, permeability, and reservoir heterogeneity on the effectiveness of EOR methods. The findings of the study will be presented in a detailed discussion, highlighting the key factors influencing the selection and optimization of EOR techniques for mature oil fields. The analysis will consider technical, economic, and environmental aspects to provide a holistic perspective on the feasibility and sustainability of implementing EOR methods in mature oil reservoirs. In conclusion, the research on the optimization of enhanced oil recovery techniques for mature oil fields aims to contribute valuable insights and recommendations for the oil and gas industry to enhance oil production from mature reservoirs. By identifying the most effective EOR strategies and optimizing their application, this project seeks to unlock the untapped potential of mature oil fields and ensure sustainable energy production in the future.
