Sinopec tested 22 MMcf/d of gas, through a 14 mm choke under well head pressure of 35.87 Mpa, in a horizontal shale gas development well in the Sichuan Basin on 11 April 2019. Jiaoye 189-8H, located in Pingqiao area of Jiaoshiba field second phase block, has a TD of 4,597 m with a horizontal section of 1,708 m. The well achieved a record high flow rate in the field so far after a 16-stage fracking. It is said that an advanced fracking technology is applied on the fracking operation and the success indicated a way to mitigate the risk of complex geology in the field.   Currently, Sinopec has 33 wells on stream in Pingqiao area with production rate of 74 MMcf/d of gas.   Background Information  In 2018, Sinopec produced 6 Bcm of shale gas from the Jiaoshibas field in the Sichuan Basin, same as in 2017. The company plans to produce 6.3 Bcm in 2019.   In 2018 Sinopec put additional 81 wells on stream in the field and added 5.4 Bcm of gas reserves. Jiaoshiba field has produced cumulative of 21.5 Bcm of shale gas by 2018 since it produced gas in 2012.   Sinopec completed Jiaoshiba field first phase development by end 2015, building a production capacity of 5 Bcm per year. The company started Jiaoshiba field 2nd phase development program in early 2016, focusing on drilling program in Jiangdong, Pingqiao, Baitao and Baima blocks.Â    Apart from the Jiaoshiba field, Sinopec also has achieved several successes in shale gas exploration drilling in other blocks in the Sichuan Basin, such as Yongchuan, Weiyuan-Rongxian and Dingshan area, in particularly Weiyuan-Rongxian block has been approved 4.4 Tcf of gas in place in 2018.   China has approved cumulative of over 37.6 Tcf of shale gas in place reserves by end 2018. Currently all shale gas fields are found in the Sichuan Basin, such as Jiaoshiba, Weiyuan, Changning, Zhaotong and Weirong.Â    China produced over 10 Bcm of shale gas in 2018.
