The Tarim oilfield branch of PetroChina, China's largest oil and gas producer, said the Luntan One well, the deepest oil well on land in Asia, has been confirmed to yield a daily output of more than 100 tons of crude oil and 50,000 cubic meters of natural gas. The Luntan One well, with a current depth of 8,882 meters, has smashed seven well drilling records around Asia since it went into operation in 2018.
