China achieved a technological breakthrough at an ultra-deep well on the edge of the Taklamakan Desert in northwest China's Xinjiang Uygur Autonomous Region by setting a new daily drilling record of 2,006 meters. The announcement came as drilling work was completed at the "Ha 13-H9" well in the Tarim Oilfield, located in Shaya County of Aksu Prefecture, reaching a final depth of 7,341 meters. More than 120 cities in 15 provincial-level regions across China have benefited from the natural gas supplied by China National Petroleum Corporation's Tarim Oilfield.
