North China has the most productive oil and gas producing basins in the country, including Songliao, Bohai and Ordos. The principal reservoirs in these basins are Mesozoic and Cenozoic clastics, although recent exploration for gas has been successful in carbonates, such as from Ordovician targets in Ordos and Bohai. The complex tectonic evolution of many of the basins in North China, however, is not fully understood, and models to assess variations in subsurface carbonate reservoirs are not well established. This region is designated to form the hub for China’s subsurface carbon dioxide storage programme.
Map of Region
CASP has a long history of research in the basins of North China, beginning with a series of Chinese literature-based reviews in the early 1990s. More detailed analytical work followed based on excellent subsurface analogues in eastern Ordos and southern Bohai, along with subsurface petrographic studies of Ordovician and Cenozoic carbonate reservoir samples from the Dagang and Shengli oilfields, Bohai. All work was carried out in collaboration with Chinese researchers from the Academia Sinica and the Academy of Geological Sciences. Thirteen reports are available covering a number of aspects of the geology in these basins.
