In 2010, the Group persisted in its drive for scale, efficiency and scientific exploration and placed emphasis on key basins and target areas, as well as strengthening pre-exploration, venture exploration and meticulous exploration. The Group made strategic discoveries in major exploration areas, such as the Erdos Basin, the Qaidam Basin, the Bohai Bay Basin, the Tarim Basin and the Sichuan Basin, thereby building up a solid foundation for the continuation of the17“Peak Growth in Oil and Gas Reserves” Program.
