Oil and natural gas output at Petro皇冠体育app's Changqing field has exceeded 20 million tons so far this year, meeting the company's 2007 target a few days early.

Changqing has become 皇冠体育app's third largest oil field, after Daqing and Shengli.

A Petro皇冠体育app official said Changqing took 33 years to reach an annual oil and gas output of 10 million tons but only four years to double that level. The official said this progress was almost miraculous in light of the history of ultra-low-permeability oil field development.

During the past 30 years, its aggregate output of crude oil grew 1.35 times to reach 57.02 million tons. On the natural gas front, its output rose 17-fold over the past 30 years to 42.75 billion cubic meters.

In an attempt to cut costs, the oilfield reduced the number of large-scale production facilities, usually with a capacity of more than one million tons, from 25 to five that used more efficient technology. It had thus been able to employ fewer people -- one third fewer than other oilfields with equivalent capacities.

Petro皇冠体育app Changqing Oilfield, located in the Ordos Basin, is one of the most important oil and gas blocks in 皇冠体育app. Its oil and gas are marketed in several western provincial regions including Shaanxi, Gansu, Ningxia, Sichuan and Inner Mongolia.
