Since September 2004, the Tarim Oilfield of China National Petroleum Corporation, the country's leading oil and gas producer, had supplied 350 billion cubic meters of natural gas to central and eastern parts of China via the country's West-to-East gas pipelines as of 8 a.m. Friday.

This volume of natural gas has helped reduce the use of standard coal by 466 million tonnes and cut carbon dioxide emissions by 757 million tonnes, according to the oilfield.

According to statistics, the natural gas supplied by the oilfield has benefited more than 120 cities in 15 provincial-level regions in China.

The Tarim Oilfield, located in Tarim Basin, is a major petroliferous basin in northwest China's Xinjiang Uygur Autonomous Region. ■
