The Ordos Basin: Sedimentological Research for Hydrocarbons Exploration provides an overview of sedimentological approaches used in the lacustrine Ordos Basin (but also applicable in other marine and lacustrine basins) to make hydrocarbon exploration more efficient. Oil exploration is becoming increasingly focused on tight sandstone reservoirs and shales. The development of these reservoirs, particularly regarding the sedimentary processes and the resulting sediments, are still poorly understood. Exploration and exploitation of such reservoirs requires new insights into the lateral and vertical facies changes, and as already indicated above, the knowledge surrounding facies and how they change in deep-water environments is still relatively unclear.
