Manshen 1 flow tested approximately 3,925 bo/d and 13.1 MMcfg/d through a 10mm choke from the Ordovician marine carbonate reservoir on 8 April 2020. The success of Manshen 1 confirmed the continuation of the marine carbonate reservoir between the Tabei Uplift and Tazhong Uplift of the Tarim Basin thus expanding the potential of the marine carbonate reservoir by 3,520 sq km. Manshen 1 was spudded on 6 August 2019 and was drilled to a TD of 7,665.6m MD (PTD 7,941m) on 15 March 2020. Manshen 1 was targeting the Ordovician Yijianfang Formation. Manshen 1 is likely located in the PetroChina operated Halahatang Block in the Tarim Basin. 
Manshen 1 nfw, is likely located in the PetroChina 100% Halahatang Block in frontier area between the Tabei + Tazhong uplifts, tested 4430 bo/d + 13 MMcfg/d on 10mm choke from ab. 8000m in Ordovician-Cambrian carbs, 54m total pay. The test results leads PetroChina to estimate that the Manshen structure has oil reserve potential of lent or 1,665 Bboe.
