PetroChina â Sichuan achieved high gas flow rate from Moxi 022-X43 in the Moxi block of the Anyue field, Sichuan Basin, on 19 November 2019. The well tested an open flow rate of about 19,461 Mscf/d (551.2 Mcm/d) of gas, with H2S content of about 16.13 ppm, from the Upper Sinian Dengying 4 Member, between 5,119 and 6,300 m, after acidizing stimulation.  Moxi 022-X43 is a development well, located in the Moxi 13 well block of the Anyue field, it is one of the Anyue field Dengying Formation Phase II development production capacity building wells, with drilling purpose to develop the Dengying 4 gas reservoir in the Moxi block. The well was spudded on 18 March and completed to a TD of 6,300 m in the Dengying 4 Member on 10 August 2019. Wireline log indicated 825.5 m of reservoir in the Dengying 4 Member.   By the end of November 2019, 18 wells drilled for the Phase II project had all tested high flow rate, with an aggregated open flow rate of about 703.65 MMcf/d (19.93 MMcm/d). An average flow rate is about 23.66 MMcf/d (670 Mcm/d) per well.   The Anyue field produced 403 Bcf of gas in 2018 and has produced a cumulative of over 1,480 Bcf of gas by the end of 2018.  Anyue field, comprising of two blocks â Moxi and Gaoshiti, has main reservoir in the Lower Cambrian Longwangmiao Formation and secondary reservoir in the Upper Sinian Deng 2&4 members. PetroChina has developed Longwangmiao reservoir in the Moxi block and build 1.1 Bcf/d of gas capacity by the end of 2015. Meanwhile the company started to develop Upper Sinian reservoir in Gaoshiti block in 2016.   Â   Background Information  Anyue gas field is the first large-scale uncompartmentalized gas field that has ever been discovered in China, with proven reserves greater than 23 Tcf by the end of 2018. It is situated on the southwestern part of a gentle structural belt, the middle part of the slope of the Leshan â Longnvsi paleo-uplift, in the central Sichuan Basin, spanning Suining and Ziyang cities in Sichuan Province and Tongnan County in Chongqing Municipality.  The Anyue field was discovered as early as in 1962, when Tong 1 tested commercial gas and condensate with flow rate of 603.73 Mscf/d of gas and 16.79 b/d of condensate from the shallower Triassic Xujiahe 2 Member reservoir. In 2011, Gaoshi 1 discovered a significant reservoir pool in the field, testing 36 MMcf/d of gas from the Upper Sinian Dengying Formation. In September 2012, Moxi 8 was successful in finding another significant reservoir pool within the dolomitic horizon in the Lower Cambrian Longwangmiao Formation. This well tested 37.7MMcf/d of gas.   PetroChina announced it as a giant gas field discovery in February 2014 and reported the field has been approved to contain 15.5 Tcf of gas in-place with recoverable volumes of 10.8 Tcf in the Longwangmiao Formation.   PetroChina started development of the Longwangmiao reservoir in 2013 in three phases. First phase was completed in November 2013 with production capacity of 100 MMcf/d of gas. Second phase started in December 2013 and was onstream in September 2014 with additional gas output capacity of 400 MMcf/d of gas. The third phase started in December 2014 and completed in November 2015 with further 600 MMcf/d of gas production capacity. By the end of 2015, the field has been on full operation with a total production capacity of 1.1 Bcf/d, and has produced cumulative 318 Bcf of gas since December 2012.   PetroChina put the first Sinian Dengying reservoir development well, Gaoshi 001-X3, onstream on 5 May 2016. The well produced at a rate of 3.5 MMcf/d of gas. It was completed in February 2015 with a TD of 5,818 m and tested 9.5 MMcf/d of gas with H2S content of 16.83 ppm in the Sinian.
