The Lingshui 25-1 structure is located in the northeast of Ledong Sag in Qiongdongnan Basin of South China Sea, with an average water depth of about 980 meters. The discovery well Lingshui 25-1-1 was drilled and completed at a depth of about 4,000 meters and encountered the oil and gas pay zone with a total thickness of about 73 meters. The well was tested to produce about 35.6 million cubic feet of natural gas and 395 barrels of oil per day.

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.
