CNOOC Limited has made a major oilfield discovery of Huizhou 19-6 in the deep and ultra-deep plays of the South China Sea, which adds over a hundred million tons of oil equivalent in-place.
Huizhou 19-6 oilfield is located in the eastern South China Sea, with an average water depth of approximately 100 meters. The main oil-bearing plays are Paleogene Enping Formation and Wenchang Formation, and the oil property is light crude. The discovery well HZ19-6-3 was drilled and completed at a depth of 5,415 meters, which encountered a total of 127 meters oil and gas pay zones. The well was tested to produce 413 barrels of crude oil and 2.41 million cubic feet of natural gas per day. Through continued exploration, the proved in-place volume of Huizhou 19-6 oilfield has exceeded a hundred million tons of oil equivalent.

Mr. Xu Changgui, the Chief Geologist of the Company, said, “In recent years, CNOOC Limited has strengthened the research on exploration theory and technology of the deep and ultra-deep plays in the South China Sea, and breakthroughs have been achieved. This discovery has confirmed the largest integrated clastic oilfield in the northern South China Sea in terms of original oil in place, breaking the traditional theoretical understanding, and demonstrating the enormous exploration potential of deep and ultra-deep plays in high-temperature and highly active basins offshore China.”
Mr. Zhou Xinhuai, CEO of the Company, said, “CNOOC Limited has made numerous breakthroughs in oil and gas exploration in the eastern South China Sea. Oilfields with hundred-million-ton oil in-place have been discovered in this area for two consecutive years, making it a new driver of the offshore oil and gas production growth. The Company will continue to strengthen its efforts in oil and gas exploration and development, to consolidate the resource base for increasing reserves and production, so as to bolster the high-quality development of the Company.”
