Start-up of Aasta Hansteen
Friday 31 August 2018
The Norwegian Petroleum Directorate has granted consent for start-up of the Aasta Hansteen facility in the Norwegian Sea. Operator Equinor plans to start production during the course of autumn 2018.
Consent for start-up of Aasta Hansteen is granted to the licensees in production licences 218 and 218 B.
Aasta Hansteen is located approx. 320 kilometres west of Bodø. Water depth in the area is 1270 metres. The field is developed with a SPAR platform (a floating installation with a vertical cylindrical hull anchored to the seabed).
The Aasta Hansteen field is setting many records. Never before has equipment been installed on the Norwegian Shelf at a depth of nearly 1300 metres. The SPAR platform is the first of its kind in Norway, and the largest in the world with its 70,000 tonnes. The facility is also the first in the world with a condensate storage tank.
Two subsea templates, each with four slots, and two subsea templates with one slot each (satellites) are placed on the seabed. The drilling of wells on the field is progressing well, and a total of eight production wells will be drilled.
Investment costs for development of the field are expected to amount to around NOK 37.5 billion, which is within the range of uncertainty indicated in the plan for development and operation (PDO).
The Snefrid Nord discovery, made in 2015 in production licence 218, has been included in the Aasta Hansteen development, subsequent to the PDO. The expected investment cost is just under NOK 1 billion.
Equinor estimates the expected recoverable reserves for Aasta Hansteen, including Snefrid Nord, at 55.6 billion standard cubic metres (Sm3) gas and 0.6 million Sm3 condensate. Gas from Aasta Hansteen will be transported in the Polarled pipeline to the Nyhamna terminal in Møre og Romsdal for further export to the United Kingdom. Produced condensate will be loaded onto tankers and shipped to the market.
