RWE Dea eyes subsea development for Zidane

RWE Dea Norge AS and partners have decided to use subsea wells tied back to the platform on Heidrun oil and gas field to develop their Zidane natural gas discovery on the Halten Bank offshore Norway (OGJ Online, Dec. 8, 2010).

The company expects to apply for government approval to install a four-slot subsea template and drill four production wells. The wellstream would flow through a 15-km, thermal-insulated flowline to the Heidrun platform, which lies to the southeast. A gas treatment and export module would be installed on the platform. Existing Heidrun facilities would stabilize condensate and treat water.

RWE Dea estimates reserves at 14-22 billion cu m of gas in the Middle Jurassic Fangst group.

Zidane lies on 344 m of water on Production License 435.

Interests are RWE Dea (operator), 40%, and Edison International Norway Branch, Maersk Oil Norway AS, and OMV (Norge) AS, 20% each.
