Thesis Overview

The project titled "Enhanced Oil Recovery Techniques in Offshore Reservoirs: A Comparative Study" aims to investigate and compare various enhanced oil recovery (EOR) techniques specifically tailored for offshore reservoirs. Offshore oil fields present unique challenges due to their remote locations, complex geology, and harsh operating conditions. Therefore, identifying the most effective EOR methods for maximizing oil recovery in these reservoirs is crucial for the oil and gas industry. The research will begin with a comprehensive literature review to explore existing EOR techniques used in offshore reservoirs worldwide. This review will cover methods such as water flooding, gas injection (CO2 and natural gas), chemical injection (polymer, surfactant, alkaline), thermal methods (steam injection), and emerging technologies like microbial EOR. By analyzing the strengths and limitations of each technique, the study aims to provide a comparative analysis to determine the most suitable EOR method for offshore applications. The research methodology will involve collecting data from case studies, field experiments, and simulation models to evaluate the performance of different EOR techniques in offshore reservoirs. Factors such as reservoir characteristics, fluid properties, well configuration, and economic feasibility will be considered in the analysis. The study will also assess the environmental impact and sustainability of the EOR methods to ensure compliance with industry regulations and best practices. Through a detailed discussion of findings, the research will present insights into the efficiency, cost-effectiveness, and technical challenges associated with implementing EOR techniques in offshore reservoirs. The comparative analysis will highlight the potential benefits and risks of each method, providing valuable information for decision-makers in the oil and gas sector. In conclusion, this project aims to contribute to the advancement of EOR technologies in offshore reservoirs by identifying the most effective techniques for improving oil recovery rates. By comparing different methods and evaluating their performance under offshore conditions, the research seeks to guide industry practices towards sustainable and efficient oil production in challenging marine environments.
