PetroChina â Xinjiang has achieved several exploration successes in 2018 in the Junggar Basin. Da 18, drilled in the east of Mahu field, tested oil in the Lower Wurhe Formation, confirming a third reservoir in the Mahu field after Triassic Baikouquan and Upper Wurhe formation.   Chepai 18, located in the Hongche fault belt in the northwest section of the basin, tested oil in the Permian Jiamuhe and demonstrated a new exploration prospective in mid-shallow horizon in this area.  Fu 32, drilled in the Fudong slope, tested 625 b/d of oil and 318 Mcf/d of gas from the Jurassic channel sands in the Toutunhe formation, indicated exploration prospective in this play in the area.   Kemei 002, drilled in the south of Kelameili gas field, tested 3.9 MMcf/d of gas in the Carboniferous reservoir. The well is to test upside reserve potential in the lower part of the structure and during drilling the well penetrated two sets of gas pay with overall 100 m thick.   Background Information  PetroChina has been operating in the Junggar Basin for more than 60 years. The company has found more than 30 fields with a total of 2.6 bn tons of oil in place in the basin and produced cumulative of 360 million tons of oil by 2017.Â  Peak oil output used to be 244,000 b/d n 2008. For the last five years PetroChina maintained oil production at a rate of over 220,000 b/d. In 2017 PetroChina produced at 226,000 b/d of oil in 2017, it plans to produce 229,000 b/d of oil in 2018.The company has a target to increase production up to 260,000 b/d by 2020
