China's biggest crude oil companies are state-owned energy conglomerates with sprawling international operations in oil and gas exploration and production; petroleum and chemical processing; storage and transportation; and many other functions along the oil and gas supply chain. This list includes the top five Chinese producers of crude oil by volume, ranked according to gross revenues reported in 2014 consolidated financial statements.

China Petroleum and Chemical Corp. (NYSE: SNP), known as Sinopec, is an oil, gas and chemical giant with more than $440 billion in consolidated revenue. The company produced nearly 361 million barrels of crude oil in 2014.
