Field Development

Statoil has selected a spar platform concept to develop the Aasta Hansteen field. Considered a deepwater pioneer in the Norwegian Sea, the Aasta Hansteen field may be the first to have a spar platform on the NCS.

The spar platform will consist of a large-diameter, single vertical cylinder supporting a conventional deck with processing facility, accommodation quarters and other facilities. The installation will fix to the seabed. The development concept will include two subsea templates with four wells on each and one satellite template with one well. The platform will house accommodation quarters for a permanent crew, a storage unit for condensate, and a gas processing facility with a capacity of 812 MMcf/d.

Gas will be exported through a 300-mile-long (483-kilometer-long), 30-36 inch diameter pipeline from the Aasta Hansteen field to the onshore processing facility at Nyhamna.

Statoil Selects Spar Concept for Luva Development
Type: Development Activity

Jan. 2012 - Statoil has selected a spar platform to develop the Luva field. Considered a deepwater pioneer in the Norwegian Sea, the Luva field may be the first to have a spar platform on the NCS. "This development may represent the start of deepwater production in the Norwegian Sea, and it will enable the tie-in of other discoveries in the same area," said Ivar Aasheim, Statoil's senior vice president for NCS field development. The spar platform will consist of a large-diameter, single vertical cylinder supporting a conventional deck with processing facility, accommodation quarters and other facilities. The installation will fix to the seabed. The development concept will include two subsea templates with four wells on each and one satellite template with one well. The platform will house accommodation quarters for a permanent crew, a storage unit for condensate, and a gas processing facility with a capacity of 812 MMcf/d. Gas will be exported through a 300-mile-long (483-kilometer-long), 30-36 inch diameter pipeline from the Luva field to the onshore processing facility at Nyhamna. The pipeline will also connect to the Linnorm field and tied-in to the Zidane field.

StatoilHydro Mulls Deepwater Luva Solutions
Type: Status Update

Oct. 2009 - StatoilHydro is still considering how to best develop the Luva gas field, located on Blocks 6706/12, 6707/10, 186 miles (300 kilometers) from land in 4,265 feet (1,300 meters) of water in the Norwegian Sea. With the results of a feasibility study in hand, the licensees have decided to spend almost two years considering possible approaches to bringing the discovery on stream. Discovered in 1997, Luva, along with two other discoveries Hakland and Snefrid South, are estimated to contain recoverable gas reserves of 40 to 60 Bcm. Developing these finds is a challenge considering their distance from land, deep water depth and the rough weather conditions, states Stale Tungesvik, head of reserves and business development at StatoilHydro. Over the next several years, various development study contracts are scheduled to be placed.
