China’s CNOOC made a new “mid-to-large sized” natural gas discovery Tuesday at the deepwater Lingshui 25-1 structure in offshore China.
The Lingshui 25-1 structure is located in the northeast of Ledong Sag in the Qiongdongnan Basin of South China Sea, with an average water depth of about 3,215 feet.
The Lingshui 25-1-1 discovery well was drilled and completed to a depth of about 13,123 feet and encountered an oil and gas pay zone with a total thickness of about 239 feet.
During testing the well produced about 35.6 million cubic feet of natural gas and 395 barrels of oil per day.
State owned CNOOC has not yet disclosed reserve estimates for the find.
The Lingshui 25-1 discovery follows of a similar gas discovery made by CNOOC’s at the Lingshui 17-2 in March 2014.
“The new discovery has not only opened up a new exploration chapter in deepwater area of northern South China Sea, but also further proven the good exploration prospects in deepwater area of Qiongdongnan Basin,” CNOOC said.
