PetroChina â Sichuan achieved a record high shale gas rate in Lu 203 in the Sichuan Basin. This horizontal shale gas appraisal well is located in Luxian County, south of Sichuan province, and has target to assess the Longmaxi shale in deep horizon (>4,000 m). The well completed with a 1,500 m horizontal section and tested 48.7 MMcf/d of gas after fracking under a well head shut-in pressure of 57.1 Mpa and bottom hole temperature of 140 dgr C.   PetroChina has completed two shale gas exploration wells in this area. Lu 201 and Lu 202. Lu 202 has been reported to test gas from the Longmaxi shale in 2018.Â  The company also achieved commercial gas flow from deep Longmaxi shale in Zu 202-H1 and Huang 202 in the south Sichuan province.   PetroChina currently has three shale gas field production blocks in the Sichuan Basin - Changning, Weiyuan and Zhaotong blocks with main shale gas production zone in the Silurian Longmaxi Formation, in addition to several exploration blocks in the basin. Overall the company has approved 11 Tcf of gas in place and has completed total 419 shale gas wells, of which 337 wells on stream by end 2019.   In 208 PetroChina produced 4.2 Bcm of shale gas from three fields in the Sichuan Basin. The company has target to produce 12 Bcm by 2020 and 24 Bcm by 2025 in the Sichuan Basin.
Lu 203 (PetroChina â Sichuan 100%) horizontal shale gas appraisal well is located in Luxian County. The well completed with a 1500 m horizontal section in Silurian Longmaxi shale in deep horizon (>4000 m) and tested 48,7 MMcf/d of gas after fracking under a well head shut-in pressure of 57.1 Mpa and bottom hole temperature of 140Â°C.
