About this Research Topic
Petroleum, as a fossil energy that is still irreplaceable in the world, and its resource exploration and development affect worldwide economic development and people's lives. In the context of carbon neutrality and carbon peaking, conventional oil and gas development methods are gradually being limited. Injecting CO2 into the reservoir for development has the unique advantage of oil displacement, and it can also effectively store CO2 in the reservoir. At present, the safe injection, effective migration and permanent storage of CO2 in the reservoir are facing many challenges. Therefore, innovations in theory and technology are urgently needed to obtain more oil and gas production and CO2 storage capacity more efficiently and safely.
Although the injection of CO2 into oil and gas reservoirs for enhanced recovery and storage has great application prospects, it also faces many challenges. For example, the corrosion of CO2 to the wellbore, the gravity separation of CO2 leads to low sweep efficiency, the phase behavior between CO2 and crude oil, etc. However, with the development of theories and technologies such as computers, materials, chemistry and mechanics, the above-mentioned problems are being continuously solved. For example, CO2 anti-corrosion technology based on big data analysis, new CO2 channeling materials and plugging technology, and chemical methods for CO2 to reduce miscible pressure, etc.
The scope of this research topic focuses on new advances in CO2 enhanced recovery and storage. Topics include but are not limited to:
• CO2 fracturing-flooding integrated technology,
• CO2 immiscible and miscible flooding technology,
• CO2 conformance improvement technology,
• CO2 leakage remediation technology,
• CO2 -crude oil miscible pressure reduction technology,
• water (e.g., nanofluid, low salinity water, etc.) alternating CO2 injection technology,
• tight oil and gas reservoir CO2 injection development and storage technology,
• shale oil and gas reservoir CO2 injection development and storage technology,
• related numerical simulation technology,
• big data analysis technology and artificial intelligence technology, etc.
Manuscripts include but are not limited to research papers, reviews, prospectives, etc.
