The annual crude oil output of China’s Bohai Sea oil field reached 30.132 million tons in 2021, accounting for one seventh of the nation’s overall annual crude oil output and becoming the country’s largest oil field, the Xinhua News Agency reported on Sunday.
The Bohai Sea oil field is operated by China National Offshore Oil Corporation (CNOOC), which started its construction in 1965. Over 4.4 billion tons of crude oil and nearly 500 billion cubic meters of natural gas had been discovered since the oil field became active, with over 493 million tons of oil and natural gas having been extracted from the oil field.
As the largest offshore oil and natural gas producer, CNOOC produced 48.640 million tons of crude oil from its domestic oil fields in 2021, a year-on-year increase of 3.23 million tons and accounting for about 80 percent of the growth in China’s total oil output, the report noted.
Wang Dongjin, chairman of CNOOC, vowed to continue oil exploration focusing on three aspects, increasing capacity and storage of oil and gas, adopting advanced technology and conducting environment protection projects, in order to maintain China’s energy security and decrease reliance on foreign energy sources.
