The Asia–Pacific region refers to the Asian regions on the west coast of the Pacific Ocean, such as East Asia and Southeast Asia, Oceania, and the islands in the Pacific Ocean, including China and Japan in East Asia, Southeast Asia, as well as Australia and New Zealand. One hundred fourteen sedimentary basins have developed in the Asia–Pacific region, covering a total area of 3794 × 104 km2. The onshore sedimentary basins have a total area of 1499 × 104 km2, where the main types of basins are cratonic, foreland and rift basins. The offshore sedimentary basins have a total area of 2295 × 104 km2, where the main types of basins are back-arc basins and passive margin basins. 12% of the world’s oil and gas resources are concentrated in the Asia–Pacific region. The total recoverable oil and gas resources in the Asia–Pacific region amount to 2250.1 × 108 tons of oil equivalent.
