CNOOC Limited said it has recently made a new mid-sized gas discovery Lingshui17-2, which indicated the first breakthrough on the independent deepwater exploration in Qiongdongnan Basin of South China Sea.
Lingshui17-2 is located in the east Lingshui Sag in the deepwater area of Qiongdongnan Basin, with the average water depth of about 1,450 meters. The discovery well Lingshui17-2-1 is drilled and completed at a depth of 3,510 meters and encountered the gas reservoir with a total thickness of about 55 meters.
The discovery has not only proven the exploration potential of structural and lithologic trap in central Canyon channel of Lingshui Sag, but also further confirmed the good exploration prospects in a deepwater area of Qiongdongnan Basin.
