Statoil Petroleum AS, operator of production licence 614, has concluded drilling of wildcat well 7324/9-1, which proved gas.
The well was drilled approx. 20 kilometres southeast of the 7324/8-1(Wisting) discovery in the Barents Sea and 300 kilometres north of Hammerfest.
The well’s primary exploration target was to prove petroleum in reservoir rocks from the Middle Jurassic to Late Triassic Age (Realgrunn sub-group). The secondary exploration target was to prove petroleum in reservoir rocks from the Late Triassic Age (the Snadd formation).
Well 7324/9-1 encountered about ten metres of gas-filled reservoir rocks in the Stø formation in the Realgrunn sub-group with good reservoir quality. About 50 metres of net reservoir rocks were encountered in the Snadd formation; they were generally of poor reservoir quality, with a few zones with good reservoir quality.
Preliminary calculations of the size of the discovery are between 1 and 2 billion standard cubic metres (Sm3) of recoverable gas. Data collection and sampling have been carried out.
The well was drilled to a vertical depth of 1060 metres below the sea surface, and was terminated in the Snadd formation. Water depth is 414 metres. The well has now been permanently plugged and abandoned.
This is the first exploration well in production licence 614, which was awarded in the 21st licencing round in 2011.
Well 7324/9-1 was drilled by the Transocean Spitsbergen drilling facility, which will move on to drill wildcat well 7125/4-3 in production licence 393 B, which is also operated by Statoil Petroleum AS.
