Xinjiang Oil Province

Xinjiang Oil Province is located in the Junggar Basin in northern Xinjiang Uygur Autonomous Region, where Karamay Oilfield, China's first large oilfield was discovered. The total oil and gas resource in Junggar reaches 10.7 billion tons, including 8.68 billion tons of oil and 2.5 trillion cubic meters of gas. By the end of 2011, the basin had accumulative proven oil in place of 2.313 billion tons and gas in place of 213.58 billion cubic meters.

On October 29, 1955, an industrial oil flow was obtained from well Ke-1 in Heiyoushan area at the northwest edge of the Junggar Basin, marking the discovery of the Karamay Oilfield. This oilfield was put into development in 1958, and produced 1.66 million tons of crude in 1960, about 40% of China’s total crude production then. In 2002, Xinjiang oil province produced 10 million tons of crude oil, becoming the first ten-million-ton oilfield in western China.

Xinjiang oil province is China's second largest heavy oil production base. In Fengcheng oilfield, which owns the largest uncompartmentalized heavy oil reservoir ever discovered in China, effective stimulation measures such as steam injection, SAGD and in-situ combustion have been taken since 2005 to boost heavy and ultra heavy oil production.

As exploration going to the basin's hinterland, three one-million-ton uncompartmentalized desert oilfields of Cainan, Shixi and Luliang were successfully discovered and put into production.

In 2016, Xinjiang Oilfield focused on the optimization of resource structure and the development of light and shallow oil reservoirs, producing 11.13 million tons of crude.

Fengcheng Oilfield

Fengcheng Oilfield, located at the northwestern edge of the Junggar Basin, has the largest uncompartmentalized heavy oil reservoir in China.

SAGD and pilot fireflood have been conducted there since 2005, resulting in a number of innovative technologies such as electric ignition, air injection and fireflood yield monitoring, as well as some matching techniques. In 2012, Fengcheng Oilfield achieved capacity growth amounting to 1.63 million tons. In 2013, Phase I project of Fengcheng-2 combined heavy oil processing station became operational.
