PetroChina â Tarim made an important discovery in the Tarim Basin. Luntan 1 tested 934 b/d of oil and 1.7 MMcf/d of gas in the deep sub-salt Wusongger Formation of the Cambrian on 19 January 2020, as a play opener well in the basin.   PetroChina â Tarim spudded this ultra-deep NFW in the Tarim Basin on 28 June 2018. Luntan 1, located in Luntai area of the Tabei Uplift, has a PTD of 8,500 m with target in the Cambrian carbonate play.   Luntan 1 was completed reaching a TD of 8,882 m by 17 July 2019. It was said this well has set a record of ultra-deep wells onshore in Asia. Sinopec drilled another ultra-deep well Ying 1 with a depth of 8,588 m in Shunbei oil/gas field in February 2019.  There are limited wells drilled in this part of the basin, and only several small discoveries in the Tertiary formations have been made in the early 1990s.   PetroChina started commercial exploration activities 30 years ago in the Tarim Basin, by end 2017 the company has approved about 7 bn bbls of oil and 60 Tcf of gas in place. In 2019 PetroChina made a significant achievement oil and gas production and produced at 113 Mb/d of oil and 2.8 Bcf/d of gas, comparing 110 Mb/d and 26 Bcm in 2018. PetroChina has a plan to produce at 120 Mb/d of oil and 3 Bcf/d of gas by 2020 in the Tarim Basin.
Luntan 1 (PetroChina 100%) in Dongqiu-Luntai block o&g disc, considered a play opener, flow tested approximately 934 bo/d and 1,72 MMcfg/d from the sub-salt Cambrian Wusongger Fm. with the objective of exploring the hc potential of the dolomite reservoir of the Lunnan-Gucheng platform margin.
