Tanzhuang-Shenqiu Depression, with an area of 2 800 km², locates in central Zhoukou basin and is a secondary structural unit which underwent two stages of superposition of fault depression during Meso-Cenozoic.  The exploration confirms that huge-thick early Cretaceous strata were deposited in Mesozoic in the depression (about 2 000 km²), with the dark mudstone having an average thickness of 1 250 m. Oil/gas show different in grade, number of layers, and thickness can be seen in many wells and oil/gas flow is found in wells such as Zhoucan well No. 10, Zhou No. 11, Zhou No. 12, and Zhou No. 19, which indicates a favorable exploration prospect.
