CNOOC Ltd. has made what it describes as a “mid-sized” natural gas discovery in the Bozhong 22-1 structure in the south-central region of Bohai Bay.
The discovery well, drilled in 25 m of water, was completed at a depth of 4,611 m, encountering a gas reservoir with a total thickness of 92 m. Gas production of the well tested at 14.2 MMcfd.
CNOOC said the Bozhong 22-1 discovery “demonstrates the good prospects of buried hills for future gas exploration of south slope in Bozhong Sag.”
The company in 2013 discovered oil and gas with the Bozhong 8-4 well and oil with the Kenli 10-4 discovery wells in Bohai Bay (OGJ Online, July 30, 2013).
Last week, CNOOC made a gas discovery in the east Lingshui Sag of the deepwater area in the South China Sea’s Qiongdongnan basin (OGJ Online, Mar. 19, 2014).
