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.

The Weizhou 12-2 and Weizhou 11-4 North are both independent oil fields where CNOOC holds 100% interest as operator.

Production from Weizhou 11-1 began in 2007 (OGJ Online, May 18, 2007); Weizhou 11-1 East in 2010 (OGJ Online, Mar. 29, 2010); Weizhou 11-2 and 6-9/610 in 2012 (OGJ Online, Oct. 19, 2012); Weizhou 6-12 in 2013 (OGJ Online, Mar. 27, 2013); and Weizhou 12-8 West also in 2013 (OGJ Online, Oct. 17, 2013).
