Abstract: The United States has developed a mature technological system for shale oil development and established a largescale operational model in this area, providing China rich geological and engineering experience in shale oil exploration and development. However, the benchmark analysis of the US shale oil cost is insufficient and superficial in China. Based on the related investigation and analysis, the main influential factors of the US shale oil cost include the resource and geographical conditions, development stages and external economic conditions. Based on the structure of the cost item, shale oil cost can be classified into full-cycle cost, half-cycle cost and development cost, of which the full-cycle cost is comparable to China’s total cost to a certain extent. Generally speaking, the US shale oil cost is on the rise. Currently, the full-cycle cost is about $60 per barrel on average, lower than China’s total shale oil cost. To promote China’s large-scale shale oil development and help the nation make scientific decisions, it is necessary to benchmark the China-US shale oil costs in detail according to regions and development stages, establish the assessment and examination system for the total cost in relations with the oil prices, policies and development stages, and strengthen technological and managerial innovation for cost control and efficient development.
