Shale Oil Development And Utilization And Its Role In Energy Industry, Xusheng Guo, Maowen Li, Mengyun Zhao

Bulletin of Chinese Academy of Sciences (Chinese Version)

Shale oil boom in the United States has catapulted it from an importer of crude oil to a net exporter. Field applications show that both the shift in exploration paradigm from finding traps to targeting resource-rich petroleum source kitchens (i.e., "sweet spots") and the technological innovation represented by horizontal well multi-stage fracturing are among the key factors for the large-scale development of shale oil in the United States. Compared with marine shale oils in North America, China's lacustrine shale oil resources have great potential, but the endowment conditions are not optimal. Early exploration and development experience shows that the adaptive …
