29/07/2022 Wintershall Dea Norge AS, operator of production licence 055, has concluded the drilling of wildcat well 31/4-A-13 C.

The well was drilled about 7 kilometres south of the Brage field and 125 kilometres west of Bergen.

The primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks in the Brent Group.

The secondary exploration target for the well was to prove petroleum in Upper Triassic to Middle Jurassic reservoir rocks in the Statfjord Group and the Cook Formation.

The well encountered about 100 metres of the Brent Group, of which 11 metres were sandstone rocks with very good reservoir quality in the Ness Formation, and 25 metres of sandstone rocks with very good reservoir quality in the upper part of the Oseberg Formation.

The well also encountered around 40 metres of the Cook Formation, of which 3 metres were sandstone rocks with poor reservoir quality, and about 40 metres of the Statfjord Group, of which 32 metres were sandstone rocks with good to very good reservoir quality.

The well is dry, without traces of petroleum.

Data acquisition has been carried out.

This is the 14th exploration well in production licence 055. The licence was awarded in 1979 in the 4th licensing round.

Well 31/4-A-13 C was drilled to respective vertical and measured depths of 2661 and 7736 metres below sea level, and was terminated in the Statfjord Group.

Water depth at the site is 137 metres. The well will now be permanently plugged and abandoned.

Well 31/4-A-13 C was drilled from the Brage platform.
