Thesis Overview

The project on "Enhanced Oil Recovery Techniques for Mature Oilfields" focuses on exploring innovative methods to recover additional hydrocarbons from mature oilfields. Mature oilfields are characterized by declining production rates and high water cuts, making it challenging to extract the remaining oil reserves. Enhanced oil recovery (EOR) techniques offer the potential to increase oil recovery efficiency and extend the economic life of these fields. The research will begin with an introduction providing background information on the importance of mature oilfields in the global energy supply and the need for advanced recovery techniques. The problem statement will highlight the challenges faced in extracting oil from mature reservoirs, such as low oil saturation and reservoir heterogeneity. The objective of the study is to evaluate and compare various EOR methods to identify the most suitable techniques for mature oilfields. The literature review will delve into existing research on EOR techniques, including thermal methods (such as steam injection), chemical methods (such as polymer flooding), and gas injection methods (such as CO2 injection). The review will analyze the effectiveness of these methods in enhancing oil recovery from mature reservoirs and discuss the key factors influencing their success. The research methodology will outline the approach taken to evaluate EOR techniques, including reservoir simulation studies, laboratory experiments, and field trials. Key aspects such as reservoir characterization, fluid properties, and rock mechanics will be considered in the evaluation process. The study will also address the economic viability and environmental impact of implementing EOR techniques in mature oilfields. The discussion of findings will present the results of the research, including the performance of different EOR methods in terms of oil recovery efficiency, production rates, and cost-effectiveness. The analysis will identify the most promising techniques for application in mature oilfields and provide recommendations for optimizing their implementation. In conclusion, the research will summarize the key findings and implications for the oil and gas industry. The study aims to contribute valuable insights into the application of EOR techniques in mature oilfields, with the potential to enhance oil recovery rates and maximize the utilization of existing resources. Overall, the project seeks to address the pressing need for sustainable energy solutions by improving the efficiency of oil production in mature reservoirs.
