Topside ready for tow-out to Edvard Grieg

Edvard Grieg oil and gas field offshore Norway has moved toward a fourth-quarter production start with completion of the platform topside at the Kvaerner ASA yard in Stord (OGJ Online, Aug. 29, 2014).

The assembly will be towed to a steel jacket in 109 m of water on Block 16/1, PL338 in the North Sea 180 km west of Stavanger.

Kvaerner, engineering, procurement, and commissioning contractor for the 22,000-tonne topside, let engineering and construction subcontracts to Aker Solutions for the process module and to Apply Leirvik for living quarters.

Under a separate EPC contract from field operator Lundin Norway, Kvaerner last year delivered the 14,500-tonne steel jacket substructure built at Verdal.

The platform has 20 well slots, living quarters with 100 single beds, and capacity for 120 persons on board.

Lundin expects plateau production of 100,000 boe/d from the Edvard Grieg deposit, which lies at about 1,900 m and includes the Lunos and Tellus discoveries in alluvial, eolian, and shallow marine conglomerates and sandstones of Triassic to Lower Cretaceous age.

The platform will work as a field center, receiving and processing oil and gas from surrounding discoveries. A 42-km pipeline will connect Edvard Grieg to the Grane pipeline for delivery of oil to Sture, Norway. Gas will move from the Edvard Grieg platform via a 90-km pipeline to the SAGE system in UK waters.

Lundin has described a “base case” of 15 wells, 9 of them producers and 7 horizontal. Some drilling has occurred through a predrilling deck atop the jacket. The Rowan Viking jack up is on the field.

Lundin has a 50% interest in PL338. Partners are OMV, 20%, and Wintershall and Statoil, 15% each.
