Sinopec achieved exploration success in the Jiaoshiba shale gas field area in the Sichuan Basin, Shengye 2HF, a horizontal shale gas outpost located in the field second phase block in south of the field, tested 11.4 MMcf/d of gas. The well is drilled on Dongshen prospect belt and gas reservoir is under normal pressure regime.  In 2018 Sinopec tested commercial gas, 5.6 MMcf/d, in Jiaoye 10HF in this part of the field, the gas reservoir is also under normal pressure regime.Â    Main producing reservoir in the field has high pressure gradient of 1.5, no well has achieved commercial gas rate in the reservoir with normal pressure regime. The success demonstrates sweet spot for normal pressure reservoir in the field area.   In 2016 Sinopec drilled Shengye 1 without result reported.  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.   Jiaoshiba field was discovered in 2013 and started production in 2014. By 2017 the field has held a total 21.2 Tcf (600.8 Bcm) of gas in place within a total field area of 576 sq km.  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.
