Synergistic Theory and Technology of CO₂ Enhanced Oil and Gas Recovery and Storage

This book reviews the industrial development and future trends of CCUS-EOR at different technological stages based on the development history and current status of CCUS-EOR globally. This book also analyzes the synergetic mechanisms in oil/gas reservoirs and the synergy and contradictions between CO2-EOR and CO2 storage. The development of CCUS-EOR is categorized into Conventional CCUS-EOR, which focuses solely on oil recovery; Coordinated CCUS-EOR, which emphasizes both oil recovery rates and storage; and Storage-Driven CCUS-EOR, which concentrates on CO2 storage. The coupled mechanisms for CO2 EOR and storage are analyzed in the context of Coordinated CCUS-EOR, considering the consistency and contradictions influenced by different factors. It ultimately provides recommendations for the sustainable development of the CCUS-EOR industry. This book is aimed at petroleum engineers working on enhanced oil and gas recovery (EOR) through the rational use of carbon dioxide to enhance oil recovery while simultaneously achieving different forms of carbon sequestration. The book has certain reference value for the future enhanced oil recovery and carbon storage in the oil industry.
