China National Offshore Oil Corp has finished the installation of 7 offshore platforms at the biggest block of the Kenli 6-1 oil field, the first 100-million-metric-ton oil platform in the northern section of Laizhou Bay in the Bohai Oilfield, further boosting oil and gas production in the region.

Located in the country's largest crude oil production base, the Kenli 6-1 oil field is capable of supplying one million cars to run for more than 20 years after being put into operation, the company said.

Bohai Oilfield produced more than 30 million tons of crude oil in 2021, contributing to half the national increase in output last year. The field's annual crude output is expected to increase by 2 million tons in the next three years and output in 2025 is set to surpass 40 million tons, helping to ensure continuity in oil and gas supply, CNOOC said.

Bohai Oilfield started its development in 1965. Over 4.4 billion tons of crude oil and nearly 500 billion cubic meters of natural gas have been located since its exploration began, and more than 493 million tons of fuel have been extracted.
