Dinan 15 flow tested approximately 635 bo/d and 2,597 bo/d from two intervals in the Second Member of the Permian Upper Urho Formation on 2 December 2019, after having achieved commercial oil flow of up to 635 bo/d from the Permian Wutonggou Formation in late October 2019. The oil exploration well was spudded on 4 July 2019 and was drilled to a TD of 3,980m MD on 15 September 2019, having encountered strong oil and gas shows in the Wutonggou and Upper Urho formations. The objective of Dinan 15 was to explore the oil and gas potential of the Wutonggou Formation in the eastern part of the Dinan 8 well, drilled by PetroChina in October 2013 and was the first well to flow test oil from the Wutonggou Formation in the Dongdaohaizi Sag, Junggar Basin. Dinan 15 is in the PetroChina operated Baijiahai Block in the Junggar Basin.
