CNOOC Ltd. declared Friday a technical breakthrough in oil and gasoline exploration with a discovery in an “ultra-shallow gasoline play in ultra-deep water” within the South China Sea.
The invention was made within the Lingshui 36-1 discipline, which has a median water depth of 1,500 meters (4,921.3 toes) within the western a part of the ocean, the oil and gasoline exploration and manufacturing firm mentioned.
“The primary gas-bearing play is the Ledong Formation of Quaternary, with a median burial depth of 210 meters [689 feet]”, mentioned a web-based assertion by CNOOC Ltd., majority held by state-owned China Nationwide Offshore Oil Corp. (CNOOC). “The sector has been examined to supply over 10 million cubic meters [353 million cubic feet] per day of open circulation pure gasoline”.
Xu Changgui, deputy chief exploration officer at CNOOC Ltd., commented, “The exploration in ultra-deep water ultra-shallow gasoline performs within the South China Sea is confronted with world-class engineering and technical challenges”.
“The profitable testing of Lingshui 36-1 is a breakthrough for the exploration in such performs”, Xu declared. “The corporate will proceed to deal with the challenges on the exploration and improvement of the assets in such performs, to expedite the utilization of pure gasoline in deep waters”.
Zhou Xinhuai, chief govt and president of CNOOC Ltd., mentioned, “South China Sea has been a significant area for the corporate to spice up pure gasoline reserves and manufacturing”.
“The profitable testing of Lingshui 36-1 additional expands the useful resource base for the event of a trillion-cubic-meters [35.3 trillion cubic feet] gasoline area in South China Sea”, Zhou added.
That is the second discovery within the South China Sea introduced by CNOOC Ltd. this yr, and the third in China.
Final March it declared a “main” discovery within the Kaiping South oilfield, which sits within the deepwater jap South China Sea in a deep play. The sector has a median water depth of about 500 meters (1,640.4 toes) in response to the corporate.
Drilled to a complete depth of three,462 meters (11,358.3 toes), the KP18-1-1d effectively discovery encountered 100.6 meters (330.1 toes) of oil and gasoline payzones. The invention added over 100 million tons of oil equal confirmed in-place assets, the primary deepwater deep-play oilfield within the East Asian nation to breach 100 million tons of in-place quantity, in response to CNOOC Ltd.
“The primary oil-bearing performs are Zhuhai Formation, Enping Formation and Wenchang Formation of Paleogene, and the oil property is gentle crude”, CNOOC Ltd. mentioned in a press launch March 8.
“The effectively was examined to supply a median of roughly 7,680 barrels of crude oil and 0.52 million cubic toes of pure gasoline per day”, it added. “By way of continued exploration, the proved in-place quantity of Kaiping South Oilfield has reached 102 million tons of oil equal”.
Xu mentioned then, “The invention totally demonstrates the broad prospects for exploration in deep-water South China Sea and additional expands the useful resource base for the corporate’s high-quality improvement”.
The opposite discovery by CNOOC Ltd. at residence this yr was made within the Bohai Sea, in northern China, by the Qinhuangdao 27-3 oilfield. The sector sits within the north-central waters of the ocean with a median water depth of round 25 meters (82 toes).
The invention effectively, QHD27-3-3, confirmed 48.9 meters (160.4 toes) of oil payzones after being drilled to 1,570 meters (5,150.9 toes). “The primary oil-bearing play is the Minghuazhen Formation of Neogene, and the oil property is medium-heavy crude”, CNOOC Ltd. mentioned in a information launch March 18.
“The sector has been examined to supply roughly 742 barrels of crude oil per day from a single effectively”, it added. “By way of continued exploration, the proved in-place quantity of Qinhuangdao 27-3 Oilfield has reached 104 million tons of oil equal”.
