CHINA'S second largest oil field, Shengli Oilfield, aims to boost its crude oil output to 27.5 million tons in 2012, up 160,000 tons from the target this year.

As the flagship oil producing unit of China's state-owned petroleum giant Sinopec, Shengli Oilfield has met the 2011 plan of 27.34 million tons of output, trailing only behind PetroChina's Daqing Oilfield in output.

Located in the Yellow River delta bordering the Bohai Sea, the Shengli Oil field was discovered in 1961 and its development began in 1964, with daily production of about 650,000 barrels.

China's crude oil production rose 6.9 percent in 2010 to exceed 200 million tons, according to the National Statistics Bureau.
