CNOOC begins production from two more Beibu Gulf fields

CNOOC Ltd. has started oil production from the Weizhou 12-2 joint development project and Weizhou 11-4 North Phase II project in the Beibu Gulf basin of the South China Sea.

The Weizhou 12-2 project, which lies in 36 m of water, includes three oil fields: Weizhou 12-2, Weizhou 12-1 West, and north part of Weizhou 11-2.

Its main production facilities comprise three wellhead platforms and 18 wells that have all begun production, flowing 16,000 b/d of oil at peak output.

The Weizhou 11-4 North project, which lies in 40 m of water, shares existing facilities and comprises two wellhead platforms and 15 production wells.

One well is currently on production, flowing 500 bo/d. Weizhou 11-4 is expected to reach peak production of 8,000 b/d within the year.
