As of late February 2018, Sinopec successfully flow tested commercial amount of shale gas from Dingye 5 after having commenced testing operations in late 2017. Dingye 5 was drilled to a TD of 5,685m MD and was suspended for fracture stimulation and testing in September 2017. The vertical section of Dingye 5 was drilled to a 3,848m in April 2017 after having been spudded on 20 December 2016. Convention cores were collected from 3,740-3,821.6m with one core measuring 16.32m. The shale gas exploration well had a PTVD of 3,700m and a 1,500m horizontal section to a PTD of 5,396m, targeting the Longmaxi Formation with the objective of collecting shale gas data in the Dingshan area. The success of Dingye 5 followed that the previous successful shale gas wells, Dingye 1, Dingye 2, Dingye 3 and Dingye 4, on the Dingshan Structure, allowing Sinopec to further explore and build the shale gas potential of the Dingshan shale gas discovery. Dingye 5 is in the Sinopec operated Qijiang Block in the Sichuan Basin and geographically located in Guizhou Province, Xishui County, Zhaiba Town.  <P /><P />
