Norsk Hydro has awarded Technip-Coflexip, through its Norwegian affiliate Technip Offshore Norge AS, the EPCI (engineering, procurement, construction, installation) contract for the Oseberg South - J Structure flowlines and umbilical.

The contract, valued at 23 million euros, includes two seven kilmetres long, 8" rigid flowlines (production and water injection) and one umbilical running from the new Oseberg J template to the Oseberg South platform.

The engineering work starts immediately and the steel flowlines will be welded at Technip-Coflexip's spoolbase in Orkanger, Norway. Installation is scheduled to take place March 2004.

Increased Oseberg production

The development of the Oseberg Sør J structure will lead to increased oil production from the Oseberg area, in addition to improving the capacity of the Oseberg platform and the existing structure.

Oseberg Sør J will be developed with a subsea template with two production and two water injection wells linked to the platform. The template and pipelines will be installed in the summer of 2004, and drilling is planned to start in August 2004.

On stream October 2004

Production start is planned for October 2004, and the field will have a peak production of 21,000 barrels oil per day. The forecast recoverable reserves are calculated at 3.8 million Sm3 oil and 0.49 billion Sm3 gas.

The development has a cost frame of around NOK 1.4 billion.
