Thesis Overview

The project titled "Enhanced Oil Recovery Techniques for Unconventional Reservoirs" aims to investigate and analyze the various methods and strategies employed in enhancing oil recovery from unconventional reservoirs. Unconventional reservoirs, such as tight oil and gas formations, shale plays, and heavy oil deposits, present unique challenges due to their low permeability and complex geological characteristics. Traditional reservoir engineering techniques are often not sufficient to extract the maximum amount of hydrocarbons from these challenging reservoirs. The research will begin with a comprehensive review of the existing literature on enhanced oil recovery (EOR) techniques specifically tailored for unconventional reservoirs. This literature review will cover a wide range of topics, including but not limited to, hydraulic fracturing, chemical flooding, gas injection, thermal methods, and emerging technologies in the field of EOR. By examining the successes and limitations of these techniques, the study aims to identify the most effective and sustainable methods for maximizing oil recovery from unconventional reservoirs. Following the literature review, the research methodology will be outlined, detailing the experimental approach, data collection methods, and analysis techniques to be employed in the study. This will include laboratory experiments, numerical simulations, and field case studies to provide a comprehensive understanding of the performance of different EOR techniques in unconventional reservoirs. The core of the research will be the discussion of findings, where the results of the experiments and analyses will be presented and interpreted. The effectiveness of various EOR techniques in enhancing oil recovery from unconventional reservoirs will be evaluated, considering factors such as reservoir characteristics, fluid properties, and economic feasibility. The discussion will also highlight any challenges or limitations encountered during the study and propose recommendations for further research and industry application. In conclusion, the project will provide a detailed summary of the key findings and insights gained from the research on enhanced oil recovery techniques for unconventional reservoirs. The significance of the study lies in its potential to contribute to the advancement of EOR methods specifically tailored for challenging reservoirs, ultimately leading to increased oil production and improved energy sustainability. By addressing the critical need for innovative solutions in the oil and gas industry, this research aims to provide valuable knowledge and practical recommendations for optimizing oil recovery from unconventional reservoirs."
