Statoil Petroleum AS, operator of production licence 718, has completed the drilling of wildcat well 7317/9-1. The well is dry. The well was drilled about 100 kilometres northwest of the 7220/8-1 (Johan Castberg) discovery in the Barents Sea.

The primary exploration target for the well was to prove petroleum in Middle Jurassic to Late Triassic reservoir rocks (the Realgrunn sub-group). The secondary exploration target was to prove petroleum in Late to Middle Triassic reservoir rocks (Tub?en and Snadd formation), depending on the well result in the primary target.

Well 7317/9-1 encountered multiple sandstone layers in both exploration targets, totaling about 60 metres in the Realgrunn sub-group and about 50 metres that are preliminarily correlated to the Snadd formation. All sandstone layers have poor to no reservoir quality. The well is dry. Extensive data acquisition and sampling have been carried out.

This is the first exploration well in production licence 718. The licence was awarded in the 22nd licensing round in 2013. The well was drilled to a vertical depth of 1468 metres below the sea surface, and was terminated in presumed Middle to Late Triassic reservoir rocks (Snadd or Kobbe formation).

Water depth at the site is 460 metres. The well will be permanently plugged and abandoned. Well 7317/9-1 was drilled by Songa Enabler, which will now proceed to drill wildcat well 35/9-13 in production licence 682 in the North Sea, where Bayerngas Norge AS is the operator.
