CNOOC has midsized oil find in Bohai’s Liaodong

CNOOC Ltd. said it has discovered heavy oil at a midsized oil and gas structure in the Liaodong Bay area of Bohai Gulf and made another oil discovery elsewhere in the southern part of Bohai offshore China.

The Luda 5-2N-2 and LD 5-2N-4 discovery wells in 31 m of water were both drilled and completed at a depth of around 1,140 m and encountered oil pay zones with total thickness of 120 m and 85 m, respectively. The company tested Luda 5-2N-2 at 1,040 b/d.

CNOOC said the Luda 5-2 North discovery “demonstrates the company’s successful experience in the thermal recovery technology of heavy oil, and creates a new methodology to commercialize heavy oil reserves.”

Kenli 9-5/9-6 is on the Laixi structure in 9 m of water. The company drilled the Kenli 9-5-2D and Kenli 9-6-2 wells and completed them at 2,200 m and 1,250 m, respectively, in pay zones 70 m and 120 m thick, respectively.

The company said it tested Kenli 9-6-2 at 200 b/d and that Kenli 9-5/9-6 “has further expanded the scale of the reserve in the area.”
