Qigu 8 was suspended in late July 2018 as a future gas and condensate producer, having achieved flow rate of approximately 5.75 MMcfg/d (no H2S) plus 291 bc/d through a 12" choke following acidization from the Ordovician Fengfeng Formation. Qigu 8 was spudded in early 2018 and was drilled to a TD of 4,060.41m MD in mid-2018. The success of Qigu 8 confirmed the hydrocarbons potential of the Ordovician reservoirs of buried hill structures in the Bohai Gulf Basin. Qigu 8 is the PetroChina operated Tangshi Block in the onshore Bohai Gulf Basin.
