The research methodology section outlines the approach taken to investigate the application of CCS technology in mature oilfields. This includes data collection methods, experimental procedures, and analytical techniques used to evaluate the impact of CCS on oil recovery rates and environmental sustainability. The findings of the study are presented in detail in the discussion chapter, highlighting the key results and insights gained from the research. The discussion covers the effectiveness of CCS technology in enhancing oil recovery, the economic feasibility of implementing CCS in mature oilfields, and the environmental benefits of reducing greenhouse gas emissions. The conclusion chapter summarizes the main findings of the study and discusses their implications for the petroleum industry. Recommendations for future research and potential applications of CCS technology in mature oilfields are also provided. Overall, this research contributes to the growing body of knowledge on enhanced oil recovery techniques and carbon capture and storage technologies. The findings of this study have the potential to inform industry practices and policy decisions aimed at improving oil recovery rates, reducing environmental impact, and ensuring the long-term sustainability of oil production in mature oilfields.

Thesis Overview

The project "Enhanced Oil Recovery Techniques for Mature Oilfields using Carbon Capture and Storage Technology" aims to address the challenges faced in mature oilfields by exploring innovative methods to enhance oil recovery while simultaneously reducing carbon emissions through the application of carbon capture and storage (CCS) technology. Mature oilfields represent a significant portion of global oil reserves, but their production levels have declined over time as primary recovery methods become less effective. Enhanced oil recovery (EOR) techniques offer the potential to revitalize these fields by increasing the amount of oil that can be extracted. However, traditional EOR methods are often energy-intensive and can result in increased greenhouse gas emissions, contributing to climate change. By integrating CCS technology into EOR operations, this project seeks to mitigate the environmental impact of oil production while maximizing the recovery of oil reserves. CCS involves capturing carbon dioxide (CO2) emissions from industrial processes, such as power plants or oil refineries, and injecting the CO2 underground for long-term storage in geological formations. In the context of EOR, the captured CO2 can be utilized as a secondary or tertiary recovery method to displace oil trapped in reservoirs, thereby increasing overall oil production. The research will involve a comprehensive review of existing EOR techniques and CCS technologies to identify synergies and potential challenges in integrating the two processes. This will include evaluating the technical feasibility, economic viability, and environmental benefits of implementing CCS-enhanced EOR in mature oilfields. The project will also assess the regulatory framework and policy implications surrounding CCS deployment in the oil and gas industry. Key objectives of the study include: 1. Investigating the current state of mature oilfields and the need for enhanced oil recovery methods. 2. Reviewing various EOR techniques and assessing their applicability to mature oilfields. 3. Analyzing the potential benefits and challenges of integrating CCS technology into EOR operations. 4. Evaluating the environmental impact and carbon footprint reduction potential of CCS-enhanced EOR. 5. Proposing a framework for implementing CCS-enhanced EOR in mature oilfields and outlining potential pathways for industry adoption. Overall, this project aims to contribute to the advancement of sustainable oil production practices by demonstrating the feasibility and benefits of utilizing CCS technology in conjunction with EOR techniques. By optimizing oil recovery rates and reducing carbon emissions, the research seeks to promote environmentally responsible practices within the oil and gas sector while maximizing the economic potential of mature oilfields.
