The rapid advancement in new energy development has resulted in declining security redundancy in power systems and conflicts on both sea and land usage. High-energy consuming and high-carbon emitting enterprises, such as those in oil and gas, refining, and chemical sectors, have begun to actively participate in new energy development, aiming for a clean and low-carbon transition. Consequently, the integrated development of oil, gas, and new energy has gradually emerged as a critical factor in achieving national carbon peak and carbon neutrality goals, ensuring national energy security, establishing new scenarios and modes, and stimulating the transformation of the oil and gas industry. At present, policy steer is intensifying, and social consensus is progressively forming. This study explores the feasibility of integrated development from multiple perspectives including geospatial overlap, low-carbon and security constraints, equipment and technology transformation, and mutual industry development promotion. Drawing on the experiences of oil and gas companies, this study summarizes six potential scenarios and modes, and analyzes associated challenges. Through research, the basic principles and overall approach for integrated development of oil, gas and new energy were clarified, the implementation pathway was identified, and development suggestions were put forward in terms of policies, market, technology, and international cooperation.
