CNOOC says the Weizhou 12-2 oilfield joint development project (Weizhou 12-2) and Weizhou 11-4 North oilfield Phase II project (Weizhou 11-4 North) have recently started production.
The Weizhou 12-2 project is in the Beibu Gulf basin of the South China Sea with an average water depth of approximately 36m. This 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. The main production facilities include three wellhead platforms and 18 producing wells which have all commenced production, producing a total of approximately 16,000 b/d and reaching its ODP designed peak production.
Weizhou 11-4 North project, also in Beibu Gulf basin of the South China Sea, has an average water depth of approximately 40m. The project shares the existing adjacent facilities for the development and built two wellhead platforms and 15 producing wells. There is currently one well on production, producing a total of approximately 500 b/d. The project is expected to reach its ODP designed peak production of approximately 8000 b/d within the year.
The Weizhou 12-2 and Weizhou 11-4 North are both independent oilfields in which CNOOC holds 100% interest and acts as the operator.
