China's first deepwater oilfield, the Liuhua Oilfield, has surpassed 2 million tons in cumulative crude oil production during its secondary development phase.

China's first deepwater oilfield, the Liuhua Oilfield, has surpassed 2 million tons in cumulative crude oil production from its secondary development, marking that the secondary development model for aging deepwater oilfields has withstood practical testing and providing a practical example for deepwater oil and gas development.

Why it matters. The successful development of deepwater oil fields helps enhance our country's capacity to exploit deepwater oil and gas resources, thereby ensuring energy supply.
