State-owned China National Offshore Oil Company (CNOOC) has invited firms to bid for a contract to provide workover and completion services at the Missan oil field complex in the east of Iraq.

Oil field service firms have been asked to submit their proposals by 3 February to CNOOC’s offices in Dubai.

The tender was launched on 13 January, along with a second tender for the provision of completion and stimulation services at four wells at the field, by 28 January.

The scope of services for the deals cover workovers of the existing wells, new well completion and stimulation over a period of one year. The winning contractor will have to provide a truck-mounted workover rig and other equipment.

The Missan complex contains three oil fields: Buzurgan, Abu Ghraib and Faqa. Buzurgan and Abu Ghraib were both brought into production in 1976, but were shut down from the end of 1980 until the middle of 1998 due to the Iran-Iraq war and the first Gulf war. Abu Ghraib contains 15 producing wells, while Buzurgan has 20 producing wells. The Faqa field lies on the border with Iran and was brought onstream in 1979. It has 22 producer wells.

In October, CNOOC issued tenders for the construction of a new gas sweetening facility at the complex, which will process at least 17.5 million cubic feet a day (cf/d) of natural gas.
