China has discovered a new 900-million-tonne oil and gas field in the Tarim Basin in the northwestern Xinjiang Uygur Autonomous Region after six years' intensive exploration, according to China National Petroleum Corporation (CNPC), the country's largest oil and gas producer, on Friday.

The Fuman Oilfield, where the super-deep well is situated, is the main block for crude oil production in the Tarim Oilfield. Its major oil producing zone is about 8,000 meters deep.
