Sinopec completed a mini fracture stimulation programme and test operations over the Permian Longtan Formation Shale at Dawan 4 in mid-April 2020. The testing operation was carried out between 5,840-5,886.1m and resulted in gas flame of 0.3m in height. The objectives of the testing operations were to test the commerciality of the shale gas in the deeper Permian Longtan Formation and refine techniques for further development of production testing in the deep shale gas intervals. Dawan 4 was drilled to a TD of 6,241m MD (TVD 5,997m) in the Silurian Hanjiadian Formation on 24 July 2019 and was suspended for testing in early August 2019. Wireline logging data confirmed that Dawan 4 encountered gas reservoirs in the Feixianguan, Changxing, Longtan and Maokou formations. Gas exploration well, Dawan 4, was spudded on 10 November 2018 to drill to a PTD of 6,218m (PTVD 6,040m) and was targeting the Changxing and Feixianguan formations with the objective of exploring the gas potential of the Dawan Structure to expand the Puguang gas field. Dawan 4 is in the Sinopec operated Daxian-Xuanhan Block in the Sichuan Basin and is geographically located within Sichuan Province, Xuanhan County, Maoba Town Luwang Village.<P /><P />
