09/01/2012 Statoil Petroleum AS, operator of production licence 532, is in the process of completing the drilling of wildcat well 7220/7-1.
The well was drilled about 7 kilometres southwest of the 7220/8-1 ("Skrugard") discovery and 100 kilometres north of the Snøhvit field.
The objective of the well was to prove petroleum in reservoir rock from the Middle and Lower Jurassic (the Stø and Nordmela formations). The well encountered a 48-metre gas column in the Stø formation and a 128-metre oil column in the Stø and Nordmela formations. The reservoir rocks and the reservoir quality were as expected.
Preliminary calculations of the size of the discovery range between 30 and 50 million standard cubic metres (Sm3) of recoverable oil equivalents (o.e.), of which approx. 4-6 billion Sm3 is associated and free gas.
The well was not formation-tested, but extensive data collection and sampling have been carried out. The discovery will be developed along with discovery 7220/8-1.
This is the second exploration well in production licence 532. The production licence was awarded in the 20th licensing round.
The well was drilled to a vertical depth of 2200 metres below the sea surface and terminated in the Fruholmen formation in the Upper Triassic. Water depth at the site is 365 metres. The well will be permanently plugged and abandoned.
Well 7220/7-1 was drilled by the drilling facility Aker Barents, which will proceed to drill appraisal well 7220/5-1 on discovery 7220/8-1 in the same production licence.
