China News Service, Beijing, March 8 (Reporter Wang Enbo) China National Offshore Oil Corporation announced on the 8th that it had discovered China's first large deep-water oil field, Kaiping South Oil Field, in the Pearl River Mouth Basin of the South China Sea, with proven oil and gas geological reserves of 102 million tons of oil equivalent. .
This oil field is the largest commercial discovery in a core complex type depression in the world.
Kaiping South Oilfield is located in the Kaiping Depression in the eastern part of the South China Sea, about 300 kilometers away from Shenzhen City. The average water depth exceeds 500 meters, and the maximum well depth is 4,831 meters. The oil product is light crude oil.
The discovery well was drilled into an oil and gas layer of 100.6 meters, and the average daily oil and gas production in the test exceeded 1,000 tons of oil equivalent, setting a new record for China's deep-water oil and gas test production.
On March 8, CNOOC announced the discovery of China’s first deepwater 100-million-ton oil field.

The geological conditions of the Kaiping Depression are complex and faults are crisscrossed, making exploration extremely difficult.
Liu Jun, chief geologist of CNOOC Shenzhen Branch, said that on the basis of new seismic data, it has deepened its understanding of the distribution of source rocks and oil and gas accumulation patterns, clarified oil and gas enrichment areas, and re-evaluated the amount of resources. Since 2023, it has been operating in Kaiping Exploration wells were intensively deployed in the southern region, and 4 of them tested and obtained high-yield industrial oil flows, confirming the hydrocarbon source potential of the Kaiping Depression, and successfully discovered the Kaiping Nan 100-million-ton oil field.
Compared with the traditional exploration fields of shallow water and medium-shallow layers, the degree of exploration in China's deep water and deep fields is very low, and it is an important successor area for future oil and gas reserves and production growth.
In recent years, China has vigorously strengthened scientific research and gradually made large-scale oil and gas discoveries such as the Bozhong 2.6-6 billion ton deep oil field and the Baodao 21-1 deep water deep gas field.
The discovery of the 100-million-ton oil field in Kaiping has further revealed the huge exploration potential in China's deep water fields.
Zhou Xinhuai, CEO and President of CNOOC, said that in recent years, CNOOC’s oil and gas exploration discoveries in the eastern waters of the South China Sea have repeatedly reached new highs, creating a new growth pole for the continued increase in offshore oil and gas production.
