23/09/2013 Statoil Petroleum AS, operator of production licence 608, is about to complete the drilling of wildcat well 7219/8-2. The well proved gas.
The well was drilled about 30 kilometres southwest of 7220/8-1 Johan Castberg in the Barents Sea and about 240 kilometres north of Hammerfest.
The objective of the well was to prove petroleum in Middle and Early Jurassic reservoir rocks (Stø, Nordmela and Tubåen formations).
The well encountered a gross gas column of about 200 metres in the Stø and Nordmela formations, with poorer reservoir quality than expected in both formations at the well position.
Preliminary calculations of the size of the discovery are between one and four billion standard cubic metres (Sm3) of recoverable gas. Further delineation of the discovery will be considered.
The well was not formation tested, but extensive data acquisition and sampling have been carried out.
This is the first exploration well in production licence 608.
The licence was awarded in the 21st licensing round in 2011.
The well was drilled to a vertical depth of 3382 metres below the sea surface, and was terminated in the Fruholmen formation in the Late Triassic. Water depth is 344 metres. The well will now be permanently plugged and abandoned.
Well 7219/8-2 was drilled by the West Hercules drilling facility which will now proceed to production licence 532 in the Barents Sea to drill wildcat well 7220/7-2 S, where Statoil Petroleum AS is the operator.
