well was drilled about 20 kilometres west of the Aasta Hansteen field in

rocks (the Nise formation).
well encountered a total gas column of about 70 metres in the Nise
formation, of which 40 metres in sandstone with very good reservoir
quality. Preliminary estimates place the size of the discovery between one
