Shengli Oil Field

The Shengli Oil Field (simplified Chinese: 胜利油田; traditional Chinese: 勝利油田; pinyin: Shènglì Yóutián; lit. 'Victory Oil Field') is the second-largest oil field in China. Located in the delta of the Yellow River, it was discovered in 1961, and oil production began in earnest in 1964. Oil output quickly increased, peaking in 1991 at 33.55 million tons. While output has decreased since then, enhanced oil recovery techniques have maintained oil production at high levels, producing around 650,000 barrels (103,000 m³) per day.

The Shengli Oil Field Company is a subsidiary of Sinopec. The oil field also produces natural gas, and activities have recently expanded into shale oil, solar power, and wind power. The development of the oil fields was an important contributor to the economy of the local area, playing a role in the establishment of the city of Dongying in 1983. The activities of the oil industry have damaged the local wetland areas, and contributed to local pollution.
