Daqing Oil Field

The Daqing Oil Field (), formerly romanized as "Taching", is the largest oil field in the People's Republic of China, located between the Songhua river and Nen River in Heilongjiang province. When the Chinese government began to use to pinyin for romanization, the field's name became known as Daqing.
Discovered in 1959 by Li Siguang, Wang Jinxi (who led No. 1205 drilling team) worked on this oilfield. This field has produced over of oil since production started in 1960. Daqing contained or 2.2 billion tons in the beginning; the remaining recoverable reserves are about or 500 million tons. Due to the rapid increases in production in its early days, Daqing was lauded by China's state media as a model industrial enterprise throughout the 1960s and 1970s. As of 2013 the field's production rate was about .
It is reputed that during the first two decades of the life of the field, as much as 90% of the oil was wasted.
Daqing Oilfield Company Limited, based in Daqing, is the operator of exploration and development of Daqing Oilfield. From 2004, the company plans to cut its crude oil output by an annual 7% for the next seven years to extend the life of Daqing.
Output of barrels of oil equivalent of the Daqing Field remained stable at over 40 million tons in 2012, while output at Changqing oil field was over 42 million tons, making it the most productive oil and gas field in China.
Crude output from the ageing Daqing oilfield is in decline even though the CNPC deployed some non-traditional drilling techniques. In 2019, output fell to 30.9 million tonnes from 32 million tonnes in 2018. At its peak in 2008, output stood at 40 million tonnes a year.
