PRODUCTION from two of the China National Offshore Oil Company’s wholly-owned fields in the Beibu Gulf, in the South China Sea, has commenced.

The Weizhou 12-2 and Weizhou 11-4 North are both independent oilfields in which CNOOC holds a 100 per cent interest and acts as the operator.

Located in water depths of about 36 metres, the Weizhou 12-2 project has three oilfields in total including the Weizhou 12-2 oilfield, the Weizhou 12-1 west oilfield and the north part of Weizhou 11-2 oilfield.

Overall development plan (ODP) designed peak production of about 16,000 barrels of crude oil per day has been reached, with the main production facilities of 18 producing wells and three wellhead platforms operating at full capacity.

Weizhou 11-4 North Phase II is located in water depths of about 40 metres, with two wellhead platforms and 15 producer wells currently linked to existing adjacent facilities.

Currently one well is on production, producing around 500 barrels of crude per day, with CNOOC expecting output to build to the designed peak production of around 8,000 barrels per day within the year.

Production from the first Weizhou well began in 2007.
