03/07/2014 OMV (Norge) AS, operator of production licence 537, is about to complete drilling of wildcat well 7324/7-2.
The well was drilled about seven kilometres northwest of the 7324/8-1 "Wisting Central" oil discovery and 315 kilometres north of Hammerfest.
The primary exploration target for the well was to prove petroleum in Middle Jurassic to Late Triassic reservoir rocks (Stø, Nordmela and Fruholmen formations). The secondary exploration target was to prove petroleum in Late to Middle Triassic reservoir rocks (Snadd formation).
The well encountered an oil column of about 20 metres in the Stø formation, with very good reservoir properties.
Mainly gas was encountered in sandstone layers in the Snadd formation with poor reservoir properties, and no gas gradient was established.
Preliminary calculations of the size of the discovery are between three and eight million standard cubic metres (Sm3) of recoverable oil.
A successful formation test was carried out in the Stø formation. The maximum production rate was 319 Sm3 oil and 9195 Sm3 associated gas per flow day through a 56/64-inch nozzle opening.
This is the third exploration well in production licence 537. The licence was awarded in the 20th licensing round in 2009.
The well was drilled to a vertical depth of 1679 metres below the sea surface and terminated in the Snadd formation from the Late to Middle Triassic Age. The water depth is 418 metres. The well will now be permanently plugged and abandoned.
Well 7324/7-2 was drilled by the Transocean Barents drilling facility, which will now proceed to a shipyard on Stord for five-year recertification.
