Jiatan 1 flow tested approximately 11.48 MMcfg/d through an 8mm choke after fracture stimulation between 4,360-4,396m from the Middle Member 3 of Shahejie Formation volcanic basalt on 7 May 2020. The success of Jiatan 1 has boosted the volcanic reservoir hydrocarbon potential in the Eastern Sag of the Liaohe Sub-basin. Jiatan 1 was drilled in the 2H of 2019 to a TD of 4,428m MD (PTD of 4,800m). The objective of Jiatan 1 was to explore the oil and gas potential of the volcanic reservoir of the Middle Member 3 of Shahejie Formation within the Taoyuan Structure, Liaohe Sub-basin. Jiantan 1 is in the PetroChina operated Liaohe Basin Eastern Block in the onshore Bohai Gulf Basin and is geographically located within Liaoning Province, Panjin City, Dawa District Xiongjiabao Village. 
China (Bohai Gulf B.) Jiatan (Bo) 1 op. by PETROCHINA (100%) in Eastern Liaohe Sag block, TD = 4428 m, flow tested approximately 11.48 MMcfg/d through an 8mm choke after fracture stimulation between 4,360-4,396m from the Middle Member 3 of Shahejie Formation volcanic basalt
