China's First Ultra-Deepwater and Ultra-Shallow Gas Field Discovered by CNOOC

TapTechNews August 7th news, CNOOC announced the discovery of China's first ultra-deepwater and ultra-shallow gas field, Lingshui 36-1, in the southeast sea area of Hainan Island. The tested unobstructed natural gas flow rate of the exploration well exceeds 10 million cubic meters per day..

At present, the newly added proven reserves of the Lingshui 36-1 gas field have successfully passed the review and filing of relevant national departments, and the proven geological reserves of natural gas exceed 100 billion cubic meters, which is the world's first large ultra-deepwater and ultra-shallow gas field , marking a major breakthrough in China's exploration in the ultra-deepwater and ultra-shallow gas layer field. CNOOC has cumulatively proven geological reserves of natural gas exceeding 1 trillion cubic meters in the Yinggehai, Qiongdongnan, and Pearl River Mouth basins in the northern South China Sea.

TapTechNews learned from publicly available information that the average water depth of the Lingshui 36-1 gas field is about 1500 meters (about 4921 feet), and the average gas layer burial depth is 210 meters (about 689 feet). The main gas-bearing strata is the Quaternary Ledong Formation. It is another major breakthrough in CNOOC's deepwater exploration field after the oil and gas fields such as Liwan 3-1, Deep Sea No. 1 (Lingshui 17-2), Deep Sea No. 1 Phase II (Lingshui 25-1), Baodao 21-1, and Kaiping South.

The official pointed out that the successful test of this ultra-deepwater and ultra-shallow exploration well fully validates the advanced nature and reliability of the deepwater complex oil and gas resources exploration and development technology system independently established by China, and is expected to promote a further increase in domestic deepwater oil and gas production capacity.
