PetroChina â Tuha achieved a successful appraisal drilling result in the Tuha Basin. Shen 11, located in the Shenquan field, tested 135 b/d of oil and 212 Mcf/d of gas in the Jurassic formation, and it indicated a field extension to the west of the field.   Shenquan field was discovered in 1993 when Shen 1 tested 345 bo/d and 558 Mscf/d from Sanjianfang reservoir.  The field development project of Jurassic reservoir was initiated in 1996 and continuous exploration led to the discovery of additional reservoirs in the Shenquan field including those of Paleogene, Cretaceous and Jurassic in other blocks.  The field was on full production in 1997 and reached a peak production of 4,000 b/d of oil. In 2016 Shenquan field produced at a rate 1,600 b/d of oil.   Background Information  PetroChina started commercial exploration and production in the Tuha Basin in the early 1990s, by end 2017 about 20 fields have been found with daily production of 40,000 b/d of oil, down from 60,000 b/d in 1998.
